Convert Kgcm to nm: Get 1280NM

[Lorens]

We got 1.28 Kgcm

we turn cm to meter 128kgm

Then we turn it into Newton then we get about 1280NM

Problem is that i get some indication that this is wrong... is it?



(how do i get ride of overlay in explorer )

What's NM? And Kg m (or more generally Mass.Length) is not dimensionally the same as a Newton(Mass.Length.Time^-2).

It looks like one is trying to develop a moment and force or torque?

If 1.28 Kgcm = 1.28 kg-cm, then multiply by 1 m / 100 cm to to get 0.0128 kg m.

As neutrino pointed out, kg is a unit of mass and Nt (or N) is a unit of force.

1 kg * 9.8 m/s² = 9.8 kg-m/s² = 9.8 Nt or

0.102 kgf = 1 Nt.

I am not intrsted in what to do, i am interested in what i am doing wrong, you say that 1kgcm is 0.01kgm, i don't get that. It is a torque for a motor.

This is a conversion of unit problem.

I was simply pointing out the to convert a length in cm to a length in meters, one multiplies by the a factor which relates the two.

for example 1 cm = 0.01 m, or 1 m = 100 cm. The conversion factor can be 0.01 m/cm or 100 cm/m.

If a torque is written in kgf-cm and one wishes to convert it to kgf-m, then one must multiply by 1 m/100 cm, and one will get

1 kgf-cm * 1 m/ 100 cm = 0.01 kgf-m.
