SUMMARY

The discussion centers on the conversion of torque units from kilogram-centimeters (Kgcm) to Newton-meters (Nm). It is established that 1.28 Kgcm is equivalent to 0.0128 kg-m when converted correctly, and further, that 1 kgf-cm equals 0.01 kgf-m. The confusion arises from the distinction between mass (kg) and force (N), with the conversion requiring an understanding of the gravitational constant (9.8 m/s²) to relate these units accurately. The provided references offer additional guidance on unit conversions.

PREREQUISITES
  • Understanding of torque and its units (Kgcm, Nm)
  • Knowledge of unit conversion principles (cm to m)
  • Familiarity with the relationship between mass and force (kg to N)
  • Basic grasp of gravitational acceleration (9.8 m/s²)
NEXT STEPS
  • Research the concept of torque and its applications in engineering
  • Learn about the gravitational constant and its role in unit conversions
  • Explore detailed unit conversion methods for mechanical engineering
  • Investigate the differences between mass and force in physics
USEFUL FOR

Engineers, physicists, and students involved in mechanical design or torque calculations will benefit from this discussion, particularly those needing clarity on unit conversions in torque measurements.

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 )
 
Physics news on Phys.org
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.
For units conversion, here is a nice reference -
http://www.projects.ex.ac.uk/trol/scol/ccforce.htm for force
In general - http://www.projects.ex.ac.uk/trol/scol/index.htm

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.
