Conversion method
Torque and moment of force share one converter. Torque has the same dimensions as energy but a different physical meaning; do not substitute joules for torque labels.
lbf·ft = x × 0.7375621492772654

Precision of torque / moment of force conversions
All 19 torque / moment of force units convert through Newton meter (N·m). 19 have an exact defined relationship to the base unit and 0 are conventional or measured values. Results and the tables on this page come from the same engine, so a table value can be checked against the converter directly.
Standard display shows up to six decimal places, switching to scientific notation for very large or small values. Calculation uses JavaScript binary floating point independently of display rounding, so extra digits are not a claim about measurement accuracy. Each unit lists its own source; a citation records where the definition comes from, not an independent review. See Conversion methodology for the review and correction process.
