About the units
- Kilogram-force centimeter
- A kilogram-force centimeter is exactly 0.0980665 newton meters, the usual unit on servo motor specs (kg·cm).
- Pound-inch
- The pound-inch (inch-pound, lbf·in) is one pound-force at a one inch arm, exactly 0.1129848290276167 newton meters.
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 pound-inches are in one kilogram-force centimeter?
1 kgf·cm = 0.867962 lbf·in exactly.
How do I convert kilogram-force centimeters to pound-inches?
Use lbf·in = kgf·cm × 0.8679616621. For example, 25 kgf·cm = 21.699 lbf·in.
How many kilogram-force centimeters are in one pound-inch?
1 lbf·in = 1.15212 kgf·cm.
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.
