Torque Calculator
Calculate torque, moment, and rotational force
Understanding Torque
Torque, also known as moment of force, is the rotational equivalent of linear force. It measures the tendency of a force to rotate an object around an axis or pivot point. The magnitude of torque depends on both the force applied and the perpendicular distance from the axis to the line of action of the force.
How to Use the Calculator
- Enter the force magnitude in Newtons (N) or pounds-force (lbf)
- Input the radius (lever arm length) in meters or feet
- Specify the angle between force and lever arm (default 90°)
- Select your preferred unit system
- Click "Calculate" to see results
