TorqueFl torque ft lbf

Convert a measured force at a known arm into ft·lbf before setting a torque wrench target

TECHNICAL UTILITY · TORQUE_FT_LBF

Result

Enter values to begin.

torque_ft_lbf = force_lbf · arm_ft

How to use this estimate

Compute torque from force and lever arm length. How it works: torque_ft_lbf = force_lbf · arm_ft. Out of scope: bolt grade charts; prevailing torque; angle-controlled tightening. Informational calculation for the stated inputs only. Does not certify code compliance; confirm manufacturer data where it applies.
