What Physical Quantity has SI Unit $kg \cdot m$,?

Question

What is the physical quantity that has SI (System International) unit of $kg \cdot m$ (kilogram meters)?

Sometimes torque is specified in kilogram-meter meaning the weight of 1 kilogram mass at one meter lever. Assumes standard gravity of $g=9.80665 \rm m/s^2$ — John Alexiou, Apr 25 '13 at 13:16

A simple googling (takes barely 30 secs max.) can tell you the answer. Moment is something that has the "distance" along with it. Hence, moment of mass is $\mathrm{m\times kg}$. If you require another moment, $\mathrm{m^2\times kg}$. Probably, these first & second moments are engineering parameters.

Whatever, it's simply the first moment of mass..!
