About Torque Conversion

Torque is a measure of the rotational force applied to an object. It's commonly used in automotive, engineering, and scientific applications to specify how tightly bolts should be tightened, how much power engines can produce, and how much force is needed to rotate objects.

The base unit in the International System of Units (SI) is the newton-meter (N⋅m), which represents the torque resulting from a force of one newton applied perpendicularly to a moment arm of one meter.

Our converter handles all major torque units with high precision, making it easy to convert between metric, imperial, engineering, and scientific torque measurements.
