@PhyZeik ???? Your dumb

I feel like there’s something missing from the explanation of what’s replacing the unit of measure. No one actually explained what plancks constant is, how it’s used as a unit of measure. It would have been helpful to better understand why it’s a more appropriate replacement by explaining how it’s a constant measure. I searched Wikipedia & found this gave me some more context. To understand what it all means: Value The Planck constant has dimensions of physical action; i.e., energy multiplied by time, or momentum multiplied by distance, or angular momentum. In SI units, the Planck constant is expressed in joule-seconds (J⋅s or N⋅m⋅s or kg⋅m2⋅s−1). Implicit in the dimensions of the Planck constant is the fact that the SI unit of frequency, the Hertz, represents one complete cycle, 360 degrees or 2π radians, per second. An angular frequency in radians per second is often more natural in mathematics and physics and many formulas use a reduced Planck constant (or Dirac constant[citation needed]) (pronounced h-bar)

For those who are a bit confused maybe I can offer some help. Planks constant (h) is a fundamental constant in physics. When I say fundamental, I mean that it is absolutely vital to nearly every measurement and aspect of quantum physics. It is also a value found in nature, similarly to how the atomic radius of hydrogen is a set length, so is planks constant. It was originally written as E=hf to describe light (photons), where E is the photons energy and f is its frequency. You can think of planks constant like pi. Pi relates the radius of a circle to its circumference, and planks constant relates energy to frequency. The second thing that is important to understand is that the kg defines the plank constant. Without the kg, planks constant is undefined. The previous block of metal that we used to define the kg has an uncertainty in its value. Particles can evaporate off the surface, it can heat up, etc. Lab measurements are becoming so precise that they can measure planks constant so accurately, that the uncertainty in the kg block places a limit on how well they can know planks constant. So what is the solution? Instead of letting the kg define planks constant, let planks constant define the kg. And since planks constant is fundamental to nature and found everywhere, every scientist in the world can have access to the definition of planks constant, instead of going to Paris and find a block to measure it. Now as scientists perform more experiments and can more accurately write down all the digits of planks constant, the definition of the kg gets better and better too.

The same as before. Nothing actually changed at all we just rewrote a part that was quite inconvenient to be based on a natural constant. For an easier to understand example just take a look at the meter. At first it was 1/40000000 of the earths circumference. Then we measured the speed of light and got 299792458 m/s using our meter. Then we figured out that the circumference of theearth, while not really changing much, is not natural constant and it would be nicer to deefine the meter using something that always stays the same and can be found anywhere in nature. Luckily we already measured the speed of light and now the meter is 1/299792458 of the distance light travels in a second. The same with the kilogram. we measured the planck constant using the kilogram as a unit and now we can in return define the kilogram using that constant. Measurement is usually done using a kibble balance but that is a little bit too much to explain here.

The old kg is based on an object locked away in a vault. The new kg is based on a natural constant (Planck's constant) using a well defined measuring device called a Kibble balance. So now you can derive Planck's constant from first principles, take the definition of the Kibble balance and definition of the kg and reproduce the kg anywhere to 10 decimal places. And the new definition will never change over time whereas the object has already lost a few nanograms since it was created.

TLDR: The new kilogram remains equal to the old. So what changed? The definition. Huh? EARLIER: It was a single piece of metal. So, the reference was a physical object. NOW: It is a calculation. Based on a universal constant number. What number? The Planck's Constant. How does the number give me the value of Kilogram? Not explained in this video. Don't blame yourself.

G R. Because the reporter and producer did not understand it. The original math in the 1770s was flawed. The Earth circumference is not divisible evenly by metres. Therefore every other measure is based on a conceptual flaw of pre industrial amateur naturalists. SI works but the base standard is still different ways to get to the intended base, which itself was flawed. The metre became a US atomic energy commission measured wavelength after WWII. Thus the kg is now similarly based on natural physics mathematics of Plank's constant.. In reality that was an original intent, just the science was off due to miscalculating the circumference of the world. So, in reality, no measurement system today is any more or less accurate than the other. Been that way for a couple of centuries. The purpose of subdivision is the only difference.

@GH-oi2jf

G R - There are other places where the new method is explained. Not everything has to be a science lesson. This is just a news item.

If you didn't understand WTF is this all about here is a short explanation: - A kilogram is a standard metric unit for measuring weight. 1 KG is about 2.2 pounds. - Kilogram was internationally accepted as the weight of this metal ball, locked away and is forbidden to touch. (This metal ball is equal to 1 litre of water which is the amount of water you can store in a 1m x 1m x 1m cube. Point is it is not random.) - Now they have built a new way to define kilogram, using Plancks constant. The benefit is that it is artefact free, which means even if we lose the ball, or everything for that matter, we can still define how much is a kilogram and can tell if an object is a kilogram. Which means we can measure the weight without needing a ball as a reference. How do they use Planck's constant to define weight? I have no clue. Let me know if I got something wrong in the comments and I will make the edit. Like it so others can see.

As a Canadian who spent 4 months in the US, I once had a deep discussion with someone who didn't see the point of the metric system, she was a massage therapist. Without being condescending, I told her, she wouldn't. It would have little affect on her life, other than the units she used to measure but it had enormous impact on engineers, physicist, biologists, manufacturers, even pilots (#Gimliglider). Now that I work in construction in Canada VERY close to the US border, I tend to work in both units. I'll often be given a drawing in ft/in but have to order concrete in m3. It's interesting. I learned metric in school, but physical, to my eye, understand feet/inches faster, but metric is WAY easier to work with. I once asked a US engineer what is better, and they said, nothing else really makes a difference other than the feet/inches.... which I agree with, because it SUCKS to work with 2 units, to do the same thing. Computers have made it easier. But metric gives you an answer in mm, where my tolerance is greater than a mm. Feet/inches, means there is a possibility of a mistakes to be made with two systems in use. Multiply/dividing feet/inches... there is always an easier possibility of a mistake compared to mm.

You first have to explain how we measure time from an atomic phenomenon. Then you have to explain units of energy similarly to get the actual number. Of course an alien would understand that the units are arbitrary and would see that the method depanded on the relationship between mass and energy, which is the fundamental principle.

Plank's constant is the ratio between the energy of a photon and it's frequency.

I just converted my scale and it said I weigh 72kg. Almost 160 lbs. I'm 55 and just found out that 1liter of water weights 1kg.

That's by design. If the effect of the redefinition on actual measurements were non-negligible, it would mean they had done something horribly wrong. As a mechanical engineer, I think it is *wonderful* that we have officially decoupled our system of units from being dependent on any single (alterable/damageable/losable) physical object. This is the right way to define a system of units, and that's important to engineering and science as a field. Just as it is important for any individual engineer to realize that the vast majority of the time, the sane, pragmatic way to make an actual measurement is against a calibrated standard rather than the fundamental definition. Making appropriate approximations to simplify the problem (like measuring against a calibrated object rather than a universal constant) is a vital part of engineering, but so is recognizing that they *are* approximations so that you recognize circumstances where the approximation may fail (like the ways that a physical object might change and thus change your measurement of an important unit).

The pound is just a multiplier of the Kilogram, so the pound was also defined based on the International Prototype and is now defined by the new constant.

Yes. Seriously, though, does it really matter?

"Muricans: Kilogram who??

so how fast is my race car now?

1. This happened yesterday. Or rather, the decision came in effect yesterday, the vote was last year. Vice's video is late on KZread, as usual... or rather, it seems it's a repost; 2. None of the examples given really calibrated their scales with the International Prototype. The change only really potentially affects labs and manufacturers of extremely precise scales and whatnot. It's still significant, to be clear, a decision that had to happen for the betterment of science - but the video is overselling it a bit; 3. The standard for measurement of the Kilogram has changed, but the value for the kilogram itself did not. And I'm not sure if this came out clear enough. Planck's constant was used in such a way to coincide with what we consider the Kg today. So it's not like something that weighted 1Kg last week weights something different today - it's the same thing, the only thing that changed is how exactly we define that. The general problem of having a physical object defining what is supposed to be a constant is that even if you use extremely inert materials and keep it at ideal conditions, it's still gonna change overtime - which makes it NOT a constant. So, the Kg has deviated over the years... an imperceptible ammount, but it did. Micrograms. Which is impressive in itself given it's history. People talking about it not mattering because in the US you guys use pounds. Well, a pound is defined as a fractional value of a Kg, officially. So it still matters. About the meter, it's another example of unit of measurement that was changed to fit a true constant - the speed of light. A meter is nowadays defined as the length light travels for an extremely small ammount of time... it's a teeny tiny fraction of a second. But the change happened back in 1983. Back to the Planck constant... that goes waaay over my head. It's quantum mechanics. I've seen it described as the smallest action and electron can take, if that helps. But more importantly, it estabilishes a relationship between the kilogram, meters and seconds. Since the last two are already true constants, that makes the kilogram also a constant that can be calculated using a mathematical formula. Hope this helps.

Hey NASA remember when you forgot to convert the metric measurements and ended up costing $125 millions? Good going doofus.

It is being defined so that Planks constant equals one particular number. It is like defining distance with the speed of light. So instead of saying 1 metre is as long as this special stick that I keep in my garage. You say: 1 metre is the distance that light travels in 1/299 792 458th of a second.

I do not understand: Does 1kg still equal to 1000gr? Does the planck constant change the gram amount?

Which heavier *a kilogram of stell or a kilogram feathers*

If the values are staying the same. How did they get they get the first kilo to be the same as planks constant?

You could accuse absolutely every news source or even social media of clickbait if your argument is that they never went in to enough detail for you. Political news doesn't tell you every single line of a bill, your pregnant friend doesn't explain the conception etc. If you want to know how they actually use the formula, you are more than equipped to go find out.

Honestly, it sounds like you just hate Vice and are looking for any reason, be it politics or not being a science channel, to lambast them, which is pretty pathetic if it is the case.

James Creevey - You probably cannot afford the equipment to do that yourself. The standards institutes that have the equipment arrange to have physical secondary standards made. Those physical standards will go to companies that manufacture sets of reference masses. You can buy one of those sets just as you have always been able to do.
