Torque Calculator

Calculate the torque from force or mass and radius, with different units. Another name for torque is moment or moment of force. Torque is a dimension for the rotational force at an object. The unit for torque is the newton meter, Nm, this is calculated as kilograms times square meters per square second, Nm=kg*m²/s². The common Anglo-American unit is pound-foot, ft·lb. One Newton is the mass in kilograms times the gravity acceleration.

Please enter a mass or a force, as well as the radius or the moment. This calculator works with the force. If the mass is specified, the force is calculated from the mass using the locally valid gravity acceleration. Force is equal to mass multiplied by the gravity acceleration. The torque is the force multiplied by the radius.

Example: if two kilograms, fixed to an object, revolve with thirty centimeters radius, then the force is 19.62 newtons and a torque of 5.9 newton meters occurs.
