Grade calculations: calculate drop, given grade% and run (metric&ft-in)
Terms explained and calculation shown. To do this, you must be able to convert decimal inches and decimal feet to ft-in-fractions and back FAST and be able to do ratio and proportion calculations.
Error: at 6:05, 6:30 and 7:10 I say "mm" 3 times. My bad, correct is "cm". Numbers are good.

Please notice MISTAKE: in this situation it is 2.14 CM NOT 2.14 MM

Yeah, that threw me off for a min! I know it's been a while since I used metric, but I do know there is a cm in there before mm...hhehehe. Good catch Gennady :)-

Thank you. At the same time I was able to learn something even with the mistake in measurement. To anyone who uses this or understands it. The world needs you. Take care internet strangers.
What a great idea converting the number used to inchs....Deadly ;)
Your are a gentleman and scholar! Thank you for making it easy. You should make more videos.

jose rosas Thanks for sharing, will do!
good catch, thanks
Regards to this mode is it problem for one to get the slope through practical work on the site with the piping work .
Thanks for your help sir, helped me a lot! :D
Very useful video thank you👍🏽
I have a 150' of pipe which needs to drop 1/16" per foot. What is the end slope?
Good video. I thought it was cm :) Thanks a lot
What if u needed a % for a pipe laser inside the pipe.would it be the drop divided by the run times 100.ive asked 2 drainlayers.one said the drop divided by run x100.the other said run divided by drop x100

The percentage for pipe is usually always given on a plan
thank you
Aren't you the same guy who does the motorcycle gearing video showing the teeth on a sprocket?! XD

thanks bro...from india
What about taper per inch?
Or 2/100=0.02 0.02 x paip length(1.07) =0.0214 m
Hi sir cover level 5.403 and invert level 4.303 and manhole depth 1.100 and length 28 meters how mach slope in %?????
Sorry sir , check your conversion, it's supposed to be 21.4mm or 2.14cm, millimetres is x1000, centimetres is x100. Please I stand corrected

Exactly u made me think I was wrong wen I got 21.4mm...jeez thanks for these comments
👍🏻
the DROP is 2cm and 14mm or 21.4mm
Its not 2.14 mm. Its 21.4 mm or 2.14 cm. Please check again Mr. apprenticemath.
1.07m x0.02 = 2.14 cm
It should be 2.14 cm
The American portion starts at 7:20 ;)
2.14 mm is NOT 2% of 1.070 meters 21.4 is though
What are decimal feet? I'm intrigued, as it's a contradiction in term🤔😂

It's not confusing
Here slope is 21.4 mm not 2.14
Way over complicated this simple process. Convert percentage by moving decimal two place to the left and multiply by run.
actually it must be 2.14 Cm.
mm????? come on.. why dont u redo the video...
Bro your training mathematically adopted mind do the convertions faster stop the complication
that's 2.14cm
Should just take this down and re-do it imo
Too complicated for the metric! The run times the % 1.070mm run x 2% grade = 0.0214
Not 2.14mm should 21.4 mm
Why do it so complicated just 100/ 2 %=50 its mean 1:50 1/50 x paip length(1.07) =0.0214 m
I don’t believe 2% of 1.07M is 2.14mm, hahaa, Cm, not Mm🤣🤣🤣
Method of teaching is very poor
