How it works
Calculate torque magnitude using the angle between position vector and force. At 90 degrees the lever arm is fully effective.
τ = rF sin(θ)

Questions and answers
Why are some results rounded?
Results display up to 8 decimal places. Calculations use the unrounded values; very small values use scientific notation. JavaScript floating-point arithmetic can introduce tiny rounding differences.
Are my inputs sent to a server?
The calculator processes inputs in your browser. Its code does not send your values to a server.
