The force converter needs more work; being able to convert inch and foot pounds to Newton Meters would be convenient. As it is the force converter is filled with mysterious units that are not familiar to most mechanics.
as in: foot pound to inch pound to newton meters.

This is good for all those petrolheads that want to convert n*m to kgf*m.
I know this may not be as used as we may believe , however if there is a automotive or an industrial equipment troubleshooting/refurbishment professional, you will find that there is a need for a converter that enables you to use the tool you have available even if this is not the units of measurement you are used to work with.
Like they have it here: http://www.statman.info/conversions/torque.html
I use in-lbs and Nm mostly.
