Frequently asked questions

How do I convert newton-meter to foot-pound?

1 newton-meter = 0.737562 foot-pound. Choose "Newton-meter (N·m)" as From and "Foot-pound (ft·lbf)" as To, type a value, and the result updates instantly.

What torque is 100 Nm in ft-lb?

100 N·m = 73.76 ft·lbf. Going the other way, 100 ft·lbf = 135.58 N·m. Lug nuts on most cars spec around 90–120 N·m (66–89 ft·lbf).

Are torque and energy the same unit?

Both reduce to N·m dimensionally, but torque is a rotational vector quantity and energy is scalar — a 10 N·m wrench setting is not 10 joules. This tool converts torque units only.

Is my data sent to a server?

No. Conversions run entirely in your browser using fixed factors — nothing is uploaded or logged.
