How it works
For the displayed direction, 1 lbf equals 0.45359237 kgf. The engine converts through the shared force base quantity. Gravity-derived factors use standard gravity 9.80665 m/s². Ton-force means US short ton-force. The multiplier is derived from the two centralized unit factors. Keep full precision until the final result; displayed answers use up to 12 significant digits.
Worked example
10 lbf converts to 4.5359237 kgf. For the reverse direction, swap the units and enter 4.5359237 kgf; the result is approximately 10 lbf.
