Dear convert-me.com forum visitors,

Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.

All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page

Thank you for being with us and sorry for any inconveniences this could caused.

You can't actually "convert" kg to Nm. The former is a unit of mass, the latter a unit of force.

If what you wanted to do is to find the "weight" of a 600kg mass - that is, the amount of the force of gravity on a 600 kg mass - then you would need to know the strength of the gravitational field that is acting on the mass. If you're reasonably near sea level on the earth (i.e., not in orbit), that's about 9.8 Nm/kg.

So, the force of gravity acting on a 600 kg mass is F = 600 kg * 9.8 Nm/kg = 5880 N = 5.88kN That's the weight of a 600 kg mass on the surface of the earth.

Move to the Moon, where the gravitational field is only one-sixth that of the Earth, and the weight of a 600 kg mass becomes 1/6 of 5880 N = 980 N,

Question. Do ftlbs=lbs? Reason for question. Can I truly calibrate a force gage with a weight?
