Common Mistakes

    • The output is force in N, not torque in N·m. Calculating torque also needs a lever arm.

Frequently Asked Questions

Does this calculate newton-meters of torque?

No. The implemented conversion returns newtons. Torque would require a perpendicular lever-arm length as well as force.

When should I round a measurement?

Carry the measured values and conversion factors through the calculation first. Round the final result to a precision justified by the original measurements.
