Torque Calculator

Calculate torque from force and distance, or determine required force for specific torque

About this calculator

The Torque Calculator helps you determine the rotational force (torque) applied to an object by calculating the relationship between applied force and distance from the pivot point. This essential physics tool is invaluable for engineers, mechanics, students, and anyone working with rotating machinery, bolts, or lever systems. Whether you're designing mechanical systems, solving physics problems, or determining proper wrench specifications, this calculator provides instant, accurate torque measurements using the fundamental equation: Torque = Force × Distance.

How to use

Enter the force value in Newtons (or your preferred unit) and the perpendicular distance from the pivot point in meters. Click calculate to get the resulting torque in Newton-meters. Alternatively, input the desired torque and distance to find the required force, or enter torque and force to determine the necessary distance.

Frequently asked questions

What units does the torque calculator use?

The calculator supports multiple units including Newton-meters (Nm), foot-pounds (ft-lb), and inch-pounds (in-lb) for torque, with corresponding force and distance units.

How is torque different from force?

Force is a linear push or pull, while torque is rotational force that causes objects to rotate around an axis or pivot point.

What's the difference between clockwise and counterclockwise torque?

Clockwise torque rotates objects in the same direction as clock hands, while counterclockwise torque rotates in the opposite direction. Both have equal magnitude but opposite rotational effects.
