About the Inch Pound to Foot Pound
The inch-pound to foot-pound converter uses the exact relationship 1 ft·lbf = 12 in·lbf. Torque wrenches are often marked in foot-pounds while small fastener specifications are given in inch-pounds; mixing them up gives a twelvefold error. The tool converts both ways and also shows the value in newton-metres.
