Nm x 0.7376 = ft/lbs
An Nm is most probably "Newton- meter" a measure of force applied, like foot- pound.
BTU, calorie, erg, foot pound, electron volt, watt hour, newton meter
One pound per square foot equals 4.882kgf/m2
Units equivalent to Joule or energy are; Newton Meter (Nm), foot pound (f#) and electron volt (ev).
The formula would be as follows: meter * 3.2808 = feet
1 foot-pound is equivalent to: * 1.3558179483314004 newton meter (exactly) found at www.wikipedia.org
Any unit of energy is a unit of heat. Examples: -- joule -- calorie -- foot-pound -- newton-meter -- BTU -- kilowatt-hour
Foot-lbs x 1.356 = nM (approximate).
meters x 3.28 = feet
