Try google, I did find one a couple months ago.






Try Convert 4.1
Found at xxx.joshmadison.com/software freeware & very good, see photo 





It helps in figuring out how to do the conversion if you write the units correctly. Units written as kg/cm and oz/in imply that torque is force divided by distance, but it's not. Since torque is actually multiplied by distance (you get more leverage with a longer arm), the correct units are kgcm and ounceinches.
Since there are about 35.2734 ounces in a kilogram and 2.54 centimeters in an inch, the correct conversion factor is 35.2734 / 2.54 = 13.88 ounceinches/kgcm, as rmteo said.

you could also just look at the ratings of Hitec servos on their website... They list Inoz and kgcm.






Why is it not very metric?

Just type "2 kg/cm to oz/in" in the Google search box and you'll get the answer.






Right, Markus. If you use Ralph's method you'll get the answer "2 (kg / cm) = 179.191727 oz / in", which is technically correct but has nothing to do with torque. I'm not sure what sort of quantity is represented by force divided by distance, but Google doesn't seem to care.
The correct answer for torque, which Google gives for your expression, is "2 (kg cm) = 27.7747732 oz in" If you substitute Backwing's value of 1.5, you get "1.5 (kg cm) = 20.8310799 oz in"
