TORQUE FORMULAS


A6E201400004E15

• When using a torque wrench-SST or equivalent combination, the written torque must be recalculated due to the extra length that the SST or equivalent adds to the torque wrench. Recalculate the torque using the following formulas. Choose the formula that applies to you.

Torque Unit

Formula

N·m

N·m × [L/(L+A)]

kgf·m

kgf·m × [L/(L+A)]

kgf·cm

kgf·cm × [L/(L+A)]

ft·lbf

ft·lbf × [L/(L+A)]

in·lbf

in·lbf × [L/(L+A)]

A :
The length of the SST past the torque wrench drive
L :
The length of the torque wrench
