Torque Formulas
- 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 |
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)] |
A : The length of the SST
past the torque wrench drive.
L : The length of the torque wrench. |
