Torque Formulas

WARNING: This page is about a different car, the 2005 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

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 by using the following formulas. Choose the formula that applies to you.

TORQUE FORMULAS

Torque Unit

⁽¹⁾ Formula

N.m

N.m x [L/(L+A)]

kgf.m

kgf.m x [L/(L+A)]

kgf.cm

kgf.cm x [L/(L+A)]

ft.lbf

ft.lbf x [L/(L+A)]

in.lbf

in.lbf x [L/(L+A)]

⁽¹⁾	A equals the length of the SST past the torque wrench drive. See Fig 1 . L equals the length of the torque wrench.
