    You forgot one thing. All the unites are linked. For example a cube with a side length of 1 deci meter (10cm) has the volume of one liter and one liter of water is exactly 1 kg

    The video is quite good, but there are two things I have to say. The SI Unit of mass, is actually not the gram but the kilo gram, so it is the odd one in the metric system, so you can say there is the kg the normal unit and the gram is kind of a milli kilo gram. That sounds at the first moment a bit nitpicking, but is actually very important when you calculate with this units. For example 1 m*kg/s^2 = 1 N (unit for force). And to get a reference for the unit 1kg are a bit more than 2 pounds. Also the Abbreviation for Liters is actually a small l. Even if the liter is common in normal day life, the SI Unit is the cubic meter. While 1 m^3 = 1000 l. Even when it doesn't seem so, it is important to know what the basic unit is, especially for science class. Then you can get all Prefixes together (multiply and divide) then you look at your units and may change them for the sorter versions (example above), and that's it. You don't have to deal the odd factors between units anymore.

    The liter is not a unit in SI system(only an accepted unit) but it is a part of the metric system. Both L and l is used as abbreviation for liter. And yes 1 kilogram is a base unit in the SI system but kilo is still a prefix, therefore: gram is a unit in SI.

    Close but not quite. Water is about 1 kg at 4 Celsius and 1 atmosphere ... but still not quite. It also depends on the isotopic ratio. Kg is not even based on water but is a rather imprecise and artificial unit not based on natural constants. It is actually based on a physical standard weight.

    The SI comprises a coherent system of units of measurement starting with seven base units, which are the second (symbol s, the unit of time), metre (m, length), kilogram (kg, mass), ampere (A, electric current), kelvin (K, thermodynamic temperature), mole (mol, amount of substance), and candela (cd, luminous intensity). The system can accommodate coherent units for an unlimited number of additional quantities. These are called coherent derived units, which can always be represented as products of powers of the base units.[p] Twenty-two coherent derived units have been provided with special names and symbols.[q]

Please correct or delete this if I'm wrong. 1 miles is a hair over 1.6 kilometers. 1 kilometer is 0.62 miles plus a few hairs. ok, I got that for a base. 1 kilometer is 1,000 (kilo) meters. 1 meter is 100 (centi) centimeters 1 meter is 1,000 (milli) millimeters (mm) It's base 10 just like counting. We just need a visual of how large a meter is. It a yard stick plus 4 inches. ok, about.

    The abbreviation of liter is the small letter l, not the capital one. In fact in scientific use, there is no need for the liter. The volume is measured in m³, because a cube is a 3 dimensional object, each dimension measured in meters. (m). The explanation for the prefix system was quite good.

    They're not abbreviations but symbols. Abbreviations have a dot after them (like Wall St.), while symbols act as single and independent words, which means you have to add a space between them and the number (5 cm, not 5cm). Also, the main unit for volume is m^3, which equals to 1000 L; 1 L = 1 dm^3. And mass is usually measured in kg, not g: we don't say "I weight 80 000 grams"; in fact, kg is the main unit for mass, as te other units relate to mass via the kilogram: 1 N = 1 kg · m/s, for example. I guess that's because the mass of 1 L of water is 1 kg by definition. Hope I helped.

    The original definition of a meter was the length of a pendulum that swings with the period of 1 second, but time measurement at the time of actually implementing the system wasn't good enough, so they tried for another definition any country could undertake, but the definition based on the circumference of the earth was also abandoned. In the end, they had to settle for the length of a prototype. Even then, it was a great improvement because it was a single universal prototype kept carefully instead of the many local prototypes there was before. The meter could only be finally defined in a way any country could measure it with sufficient precision in 1960.

    I prove you that US using metric system in few minutes. Back in 19 century UK had this crazy monetary system Lsd- wich contained Pounds, shillings and pence. Basically 1 pound was 20 shillings, and 1 shilling was (not 5) 12 pence. One quartal of pence was called farthing(yes, farthing) and farthing also was going four ways. There was a twopence, threepence, groats(four pence) and sixpence(half shilling). Then shillings, there was a florin(2 shillings), half crown(2.5 shillings, 1/8 of a pound) and crown(5 shilling) and there was half a pound, which called "half a sovereing". Then there was a pound and paper printed big banknotes. But just to kill a little bit more, there was a guinea(little gold coin) which was worth of 1.05 pounds or 21 shillings. Simples? On the other hand US used dollars and pences, same as metric system.

    As mentioned elsewhere, it’s called the imperial system, not English. But I need to also mention that the metric system is basically French, and it’s because of this that a “metric” meter, is actually spelled Metre, NOT Meter. A Meter is a generic term for something that actually does the measuring of something, like a decibel meter etc. Metre is a proper a proper noun and it’s also the formal and legal name for this system, and therefore it doesn’t matter what Language it’s derived from, it is what it is, I don’t see anyone trying to spell Volkswagen in a English way i.e. Volkswagon, do you.

  • @andvil01

    But we have to explain why it is called the metric system. Meter is the unit for lenght. But the units for volume and weight is derived from the meter. A decimeter dm is 10 cm or 0.1 m. A cubic decimeter (dm^3) is one liter. If you have 1 liter of water at it's highest density (4 degrees Celcius) it is 1 kilogram. To lift 1 kg it takes (approx.) 10 Newton N, and if you do that for 1 m you do the work of one Newtonmeter Nm equals one Joule J of energy. It is all linked together and you can go up and down in units by the tenth. Except for area and volume in square meter and cubic meter. Then it is 100 and 1000 between the prefixed units. In 1 m^2 there is 100 dm^2 and 10000 cm^2. In 1 m^3 there is 1000 dm^3 (liters) and 1000000 cm^3. So 1 m^3 of water is 1000 kg or 1 ton and 1 cm^3 of water is 1 gram. And talking of water, thats the base for the Celcius scale. It freezes at 0 and boils at 100 degrees C (in normal atm presure).

    We still use a lot of Imperial sizes, especially in building and wood... a 2x4 = 2x4 inches unplaned wood. But in the shop it's forbidden by law to use these units in trade advertisement. In the shop it will be advertised as 38mm x 89mm. The "pond" is still used in normal speaking, but it means 500g or half a kilo, as Marco S wrote. Also the "ons" (ounce) is still used speaking, but it means 100g. So in a butchershop its quite usual if somebody asks "May I have 2 "ons" of sausage?" 200g of sausage will be cut off by the butcher.

Also today only the US and two other countrys, that are in the process of switching to metric, use it mainly and there is no connection to england in my opinion. You also forgot about Area = Squared and Volume = Cubed One tip: The converting stuff is verry important and I like it, if you write it like that: Normal: mm ×10 = cm ×10 = dcm ×10 = m ×1000 = km The normal converting number is 10 and and if you take it by the power of 2 you will get the new converting number 10 × 10 = 10² = 100 Squared: mm² ×100 = cm² ×100 = dcm² ×100 = m² ×100 = a ×100 = h ×100 = km² The same as for squared you take the 10 by the power of 3 and than we have the new number to convert with 10 × 10 × 10 = 10³ = 1000 mm³ ×1000 = cm³ ×1000 = dcm³ ×1000 = ³m ×1000 = a ×1000 = h ×1000 = km³ If you want to convert m² in km² you need to take the 3 (×100) and calculate the converting number = 100 × 100 × 100 = 100 1.000.000 and if you want convert the km in m than you need to divide the km by 1.000.000

    People shit on the imperial system, but for its day it was perfect. It was designed to standardise units of trade, for example I'll buy 1 ton of grain, instead of saying I'll buy 100 bags of grain or whatever. Metric is better because it is far more precise, and was designed to allow quick and simple conversion between standardised units.

And by the way.. mass is not equal to weight. They are completely different entities.

Also lower case "l" not a capital "L" Gram is 1/4 of a Teaspoon? Oh yeah, 1g of feathers, 1g of Hydrogen, 1g of Lead and 1g of water are all totally exactly 1/4 of a teaspoon! Also you call a lbs "large" and kg "small"? 1kg = 2.2lbs "kg is metric system version of lbs" - your imperial system is defined by metric system, meaning that pound is your version of a kilogram not vice versa "cm is metric version of in" - same as last time, inch is defined as 0.0254m or 2.54cm not the other way around. It's imperial version of the metric centimeter Centigram is not a measurement that is used. Below gram next one is a milligram which is 0.001g (0.1cg) Typical 'murican ignorance

    what a strange manner to explain ratios... Does english peoples don't know what's 1/100, 1/1000 ? is there no words for that ?

    the total bullshit: "the only difference between the metric and the english system is the name of the units and the letters we use to represent them - there is no difference in concept" - NO, LADY

    It sounds like you’re advanced enough to move beyond an intro to the metric system video where deeper explanations are forgone in order to teach beginners basic concepts.

    Kris Baeyens no, it is not. It is AS she says in the video, 1 gram.

    Gerd is right, but in fact, no one uses centigram at all. kg is the base unit of mass. g and mg are sufficient.
