About the units
- Pound-foot
- The pound-foot (also written foot-pound, lbf·ft) is one pound-force at a one foot arm, exactly 1.3558179483314004 newton meters.
- Kilogram-force meter
- A kilogram-force meter is exactly 9.80665 newton meters and still appears in some Japanese and Asian car specifications.
Limits and caveats
- Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
- Both unit factors are exact by their official definitions.
Questions about this tool
How many kilogram-force meters are in one pound-foot?
1 lbf·ft = 0.138255 kgf·m exactly.
How do I convert pound-feet to kilogram-force meters?
Use kgf·m = lbf·ft × 0.1382549544. For example, 25 lbf·ft = 3.45637 kgf·m.
How many pound-feet are in one kilogram-force meter?
1 kgf·m = 7.23301 lbf·ft.
Is a pound-foot the same as a foot-pound?
For torque, yes: both mean one pound-force on a one foot arm, about 1.3558 newton meters. Engineers often write pound-foot (lbf·ft) for torque and foot-pound for energy to keep the two apart.
Why is torque not measured in joules if both are newton meters?
Torque is a force times a lever arm at right angles to it, while work is a force times a distance along it. The dimensions match, but by convention torque is always given in newton meters.
