Torque Calculator
Calculate torque from force and distance
About this calculator
This torque calculator helps you determine the rotational force (torque) applied to an object by multiplying the applied force by the perpendicular distance from the axis of rotation. Torque is essential in engineering, mechanics, and physics applications, from designing machinery and engines to calculating bolt tightening specifications. Whether you're working on automotive repairs, construction projects, or mechanical engineering problems, this calculator provides quick and accurate torque measurements in various units including Newton-meters, foot-pounds, and inch-pounds.
How to use
Enter the applied force value in your preferred unit (Newtons, pounds, etc.) and the perpendicular distance from the rotation axis (meters, feet, inches). The calculator will instantly compute the torque using the formula: Torque = Force × Distance. Select your desired output units to get results in Newton-meters, foot-pounds, or other common torque measurements.
Frequently asked questions
What is torque and how is it measured?
Torque is rotational force that causes an object to rotate around an axis. It's measured in units like Newton-meters, foot-pounds, or inch-pounds.
Why is the distance measurement important in torque calculations?
Distance from the rotation axis directly affects torque magnitude. Greater distance means more torque for the same applied force, following the lever principle.
What's the difference between torque and force?
Force is a straight-line push or pull, while torque is rotational force that causes spinning motion around a pivot point or axis.
