Math & Numbers
Convert torque (moment of force) between N·m (SI base), lbf·ft (pound-foot), kgf·m (kilogram-force-metre), and lbf·in (pound-inch). Factors based on standard gravity g₀ = 9.80665 m/s² and 1 lbf = 4.4482216152605 N. Converts via N·m to the target unit and also lists the equivalent value in all four units for reference. Used for mechanical specs, automotive, and fastener tightening torque.
Call this tool from your code in three languages.
curl -X POST 'http://127.0.0.1:3003/en/api/tools/torque-unit-converter' \
-H 'Content-Type: application/json' \
-d '{"inputUnit":"N·m","value":100,"outputUnit":"lbf·ft","decimalPlaces":4}'Send a POST request with your inputs as JSON. File parameters require a separate upload first.
