Torque Calculator FAQ
What is torque?
Torque is the turning effect of a force acting at a distance from a pivot or axis. It is commonly calculated as torque = force × distance and is often expressed in N·m, lb·ft, or lb·in.
How do I calculate torque?
Enter the applied force and the lever arm distance, then leave torque selected as the calculated value. The calculator applies τ = r × F and converts the result into your selected torque unit.
How do I calculate force from torque?
Select force as the output, then enter torque and distance. The calculator rearranges the formula to F = τ / r, which is useful for wrench force, lever problems, and mechanical design checks.
How do I calculate distance or lever arm from torque?
Select distance as the output, then enter torque and force. The calculator uses r = τ / F to find the lever arm length required to produce the specified torque.
Which torque units are most common?N·m is the standard SI unit of torque. lb·ft is common in automotive and mechanical work in the US, while lb·in is frequently used for smaller fasteners, tools, and precision assemblies.
Can I use this torque calculator for torque wrench and automotive specs?
Yes. This calculator is useful for torque wrench settings, bolt tightening, engine and wheel fastener specs, workshop calculations, and general engineering or physics problems involving rotational force.
