🛠️ Newton Meter Calculator
Compute torque from applied force and lever length, with metric and imperial outputs.
Provide the applied force and the perpendicular distance from the pivot to the line of action to calculate torque. The tool reports newton-meters, foot-pounds, and inch-pounds for easy cross-referencing.
Enter the magnitude of the applied force.
Distance between pivot and applied force, measured in meters.

How to Use This Calculator
Input the applied force
Enter the force magnitude and choose its unit (N, lbf, or kgf).
Specify the lever arm distance
Measure the perpendicular distance from the pivot to where the force is applied, in meters.
Review the torque outputs
Use the calculated torque in N·m, lb·ft, and lb·in for tooling, actuator sizing, or analysis.
Formula
Torque (N·m) = Force (N) × Distance (m)
Force inputs in lbf or kgf are converted to newtons before multiplication. Torque is then expressed in multiple units for convenience.
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Torque describes rotational influence and is calculated as the cross product of force and lever arm distance. This calculator simplifies the process by accepting common force units and returning torque in the formats mechanics and engineers use daily.
Whether you are calibrating a torque wrench, sizing a motor, or checking hand-tool specifications, the calculator keeps all unit conversions precise and transparent.
Combine it with the Torque to HP Calculator when translating torque into rotational power, or with the Force Converter to convert input forces beforehand.
Frequently Asked Questions
Can I enter negative distances?
Distance must be non-negative. A negative result would imply reversing the direction, which is better represented by a negative force.
Does the calculator consider angle of application?
No. It assumes the force is applied perpendicular to the lever arm. For angled forces, multiply by the sine of the angle first.
Are kgf results exact?
Kilogram-force is converted using 1 kgf = 9.80665 N, matching the standard gravity definition for high precision.
What about dynamic or time-varying torque?
This tool calculates static torque. For dynamic systems, consider peak or RMS torque as dictated by your application.
