How to Convert Pound-feet to kgf·m

To convert pound-feet to kgf·m, multiply the torque by the following conversion ratio: 0.138255 kgf·m/pound-foot.

Since one pound-foot is equal to 0.138255 kgf·m, you can use this simple formula to convert:

kgf·m = pound-feet × 0.138255

The torque in kgf·m is equal to the torque in pound-feet multiplied by 0.138255.

For example, here's how to convert 5 pound-feet to kgf·m using the formula above.

kgf·m = (5 lb·ft × 0.138255) = 0.6912748 kgf·m

How Many kgf·m Are in a Pound-foot?

There are 0.138255 kgf·m in a pound-foot, which is why we use this value in the formula above.

1 lb·ft = 0.138255 kgf·m|1 kgf·m = 7.2330139 lb·ft

Our pound-foot to kilogram-force meter calculator automatically converts your torque measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

Pound-feet and kgf·m are both units used to measure torque. Keep reading to learn more about each unit.

What Is a Pound-foot?

A pound-foot is a unit of torque equal to 1.3558179 newton-meters (N·m), the base unit for torque. Equal to 1.355818 N·m. [1]

The pound-foot is classified as a US customary and imperial unit of torque. Pound-feet can be abbreviated as lb·ft; for example, 1 pound-foot can be written as 1 lb·ft.

When working with pound-feet (lb·ft) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.

In practice, pound-feet (lb·ft) are widely used across standard torque applications within US customary and imperial workflows, engineering documentation, and technical data sheets.

What Is a Kilogram-force Meter?

A kilogram-force meter is a unit of torque equal to 9.80665 newton-meters (N·m), the base unit for torque. Equal to 9.80665 N·m. [2]

The kilogram-force meter is classified as a metric and SI-compatible unit of torque. kgf·m can be abbreviated as kgf·m; for example, 1 kilogram-force meter can be written as 1 kgf·m.

In the metric system, "kilo" is the standard SI prefix for thousands, or 10³. This makes the kilogram-force meter (kgf·m) a convenient decimal multiple of the newton-meter (N·m).

In practice, kgf·m (kgf·m) are widely used across standard torque applications within SI metric workflows, engineering documentation, and technical data sheets.

When converting torque between pound-feet (lb·ft) and kgf·m (kgf·m), keep full floating-point precision (1 lb·ft = 0.138255 kgf·m; 1 kgf·m = 7.2330139 lb·ft) during intermediate calculations and round only the final kilogram-force meter figure to match your instrument tolerance.
