Kilogram-force meters to newton meters

How to convert kilogram-force meters to newton meters

1. Take the value in kilogram-force meters.
2. Use the formula newton meters = kilogram-force meters × 9.80665.
3. For example, 1 kgf·m is 9.81 N·m.

About kilogram-force meters and newton meters

A kilogram-force meter is the torque of 1 kgf (9.80665 N) acting at the end of a 1 m lever, so 1 kgf·m is exactly 9.80665 N·m. Multiply kgf·m by 9.807 to get newton meters. For a quick estimate multiply by 10, which is about 2% high.

Older Japanese and European car brochures, service manuals and torque wrenches often give engine torque and bolt torques in kgf·m, written kgm or kg-m. Modern specs use N·m, so converting lets you compare an older figure with a current one or set a newton meter torque wrench.

Examples

• 1 kgf·m (one kilogram-force meter) is 9.81 N·m
• 2.5 kgf·m (a 2.5 kgf·m spark plug torque, an illustrative value) is 24.52 N·m
• 11 kgf·m (a typical car wheel nut torque, an illustrative value) is 107.87 N·m
• 30 kgf·m (a large engine’s peak torque, an illustrative value) is 294.2 N·m
