Units of moment of force

Ed, there were a couple of odd topics that were typed by you as units of moment of force (kilograms per cubic meter and pounds per square inch). I have de-typed them, but you may want to check if you had any properties using them as units. Please double-check them.

Ok. Why are they odd? I added them because torque is commonly measured in terms of pounds per square inch or kilograms per cubic meter. How should I enter torque data?

Torque is usually measured in force × distance: foot-pounds, Newton-meters (the SI unit). This can be decomposed to mass × area ÷ time-squared; I have never heard of torque measured in units of density (mass ÷ volume, kg/m³) or pressure (force ÷ area, psi). Where are you seeing torque measured in these units? It may be a field-specific jargonistic
use of the term, but it’s not one I’ve heard before. -
Oops. I meant to add inch-pounds and went with an existing topic I mistakenly thought was synonomous. Similarly, I mistakenly thought that kilograms per cubic meter was a metric equivalent. Inch-pounds does need to be included though.

You should be able to add inch-pounds. Add a new instance of Unit of Moment of Force and give it a name. You must also give it a “Dimension” (Torque) and a “Canonical Abbreviation” (in-lb?) in order to be able to use it with a property definition. An equivalence in Newton-meters is also encouraged (0.112984829, I believe).
