Torque is gram-cm, not kg-cm.

So many misunderstandings of S.I. in one glib statement!

Firstly you don't mix names and symbols, so g-cm or gram-centimetre, but never gram-cm.

Secondly the kg is a unit of mass, not force. The "kilogram-force" or kgf would be a suitable

force unit. In SI the kilogram is the base unit, not the gram (historical reasons).

Thirdly in S.I. the newton is always the prefered unit of force, and metre the prefered unit of

length, so newton-metre or N-m is the unit of torque. And never N-cm (you can say cN-m though

.

Now a newton is a joule/metre, so newton-metres are simply joules, but that's forgetting the

rotation, hence joules/radian is actually a more logical unit but for some reason N-m is used rather

than J/rad.

Anyway at least no-one's tried to use "kg/m" or "pounds/foot" or some such real howler
