Thanks. I needed this to confirm that my conversion was correct. For those asking for a better explanation: If you have X amount of lb-ft, you convert it to N-m by using conversion factors. (X lb-ft) x (1N  / .22481 lbs) x (1 m / 3.2808 ft). The ft and lb units will cancel out, which will leave you with Newton meters as the final unit in the calculation.

This isn't how to convert Newton Meters to Pound Force Feet...That's a unit conversion and this doesn't give a unit conversion it gives a known unit conversion ratio and then does some mathematical operations using this known ratio.

Converting is to do a conversion. No wonder this video has less than seven thousand views. It's titled like it's aimed at science and math students, but takes the route of the business student.

I don't know if I should dislike this video for the awful explanation of this or like the video because I am impressed with your ability to write everything backwards from your perspective.

Example on how to ACTUALLY convert NM to ft lb.. Example 1250 NM = 921.3 ft lb. First Convert Newtons to lb. 1lb = 4.45 N (Known conversion). 1250NM x 1lb/ 4.45N = 280.898876404494 M lb. Then Convert M to ft. 1M= 3.28ft. 280.898876404494 M lb x3.28 ft /1M = 921.3 ft lb. 921.3 / 1250 = 0.737 (the conversion ratio used in video).

Are u serious? the explanation people need is how did u get the 0.7 from N*m, I mean, there is a lot of unit conversion work to get the 0.7 which is great because many would understand what the units of pound force are and the gc and all that stuff.

muchas gracias por la explicacion voy a empezar a usar un torquimetro

[motel]

Great Vid. Love the math and the commentary. I wanted to ask if an o-ring or thread engagement would alter anything? Thx.

[itwasme]

How long did it take for you to write backwards amazing ability

Thank you for post, , Really helped out... " I See said the Blind Man"

What about PSI to Joules? Is that posible?

[jol]

I wish i was one of your students lol nice vid thanks

[friendme]

It’s the correct and a simple conversion will be used to convert 1Nm to lb.ft
1Nm =(+- )0.737 lb.ft. On any instrument

[jppatel]

I don't know what's the correct way to say Nm. Is it Newton Meter or Newton Meters? As per formulae it would be Newton Meter. I have seen lot of videos people keep saying Newton Meters. Please correct me if I'm wrong.

[johnbingham]

It seems a simple question, but I cannot find the ans.What is the weight of 1 newton in grams, and ounces?

[Tony-]

Am i correct in thinking a force of ten newtons pressing on a one meter radius would equal ten NM, torque measurement.?
Or if you had say a force of thirty newtons pressing on one meter you would have a torque measurement of thirty NM ?
What i mean is, is it the newtons that increase, not the Meters/ radius. 

I have seen diagrams where it shows the radius extended.  for example A weight of 10 lb force pressing on a radius of 2 or thee meters. 

[jerryleininger]

That was a waste of time. All that did was multiply times a conversion factor. It did not explain the factor. It should have been titlled "How to multiply times a decimal"!

[andykreusel]

isn't a newton *meter the definition of a joule? A measure of energy?

[waynebulls]

google conversion calculator says that 1N is equal to aprox.0.224809lbs. I'm impressed that she can write mirrored, but if I hadn't checked I would've fucked up my homework! Plus it's not really explaining how to do the conversion.

[JosephMelia]

I get that if you divide a meter into a kilo, which is approximately 3 foot into 2.2 lbs roughly, that you will get .73 or whatever..
But it is very counter intuitive.
What I mean is this
Imagine two levers...
One for Nm
One for ft.lb
the one for Nm is a meter long, it is suspended on an axle on the far right, and on the far left, rests a one kilogram
the one for ft.lb is a foot long, it also is suspended on an axle on the far right.. and on the left rests a 1 lb weight...
ignoring the weights of the levers themselves or any frictional forces, surely, due to increased leverage by a factor of 3, and increased weight by a factor of 2.2, the Nm lever would exert around 6.6 times the force of the foot pound lever...
And yet foot pounds of torque are over 1.37 times that of newton metres...
But..I guess they mean that if you divide the length into the weight,
could you explain more about this aspect?
You have a lovely face.
lol.

Is it just me or is she actually writing backwards so it's legible from the front?
