Torque is the twisting force that turns a bolt, a shaft or a wheel, and it is one of the most frequently converted quantities in engineering and the workshop. The trouble is that the world has never settled on a single unit. A car manual might quote torque in newton-metres, a torque wrench might be marked in foot-pounds, an older spec sheet might list kilogram-force metres, and a small fastener might be rated in inch-pounds. This converter takes a value in any of these units and instantly shows the equivalent in all of the others, so you can tighten to the correct figure no matter which standard your tools or documents use. Enter a value, choose the unit you are converting from, choose the unit you want, and the result appears straight away alongside a full reference list. The method is simple and transparent. Every unit is defined by how many newton-metres it represents, which is the SI unit of torque. The calculator multiplies your input by the factor for the from unit to get a value in newton-metres, then divides by the factor for the to unit to get the answer. One foot-pound is 1.355817948 newton-metres, one inch-pound is exactly a twelfth of that, and one kilogram-force metre is 9.80665 newton-metres. Because torque and energy share the same base units, it is worth remembering that this tool converts torque, not work or energy, even though both are measured in newton-metres. It suits mechanics, engineers, students and anyone who needs a fast, dependable torque conversion.
Each unit is defined by how many newton-metres it equals. To convert, the calculator multiplies your value by the factor for the unit you are converting from, which gives a value in newton-metres, then divides by the factor for the unit you want.
value in N·m = value × factor[from]
result = value in N·m / factor[to]
| Unit | Newton-metres per unit |
|---|---|
| Newton-metres (N·m) | 1 |
| Kilonewton-metres (kN·m) | 1000 |
| Millinewton-metres (mN·m) | 0.001 |
| Foot-pounds (ft·lb) | 1.355817948 |
| Inch-pounds (in·lb) | 0.1129848291 |
| Kilogram-force metres (kgf·m) | 9.80665 |
This converter is for mechanics, engineers, technicians and students who need to switch a torque figure between metric and imperial units, whether for tightening fasteners, reading a spec sheet, or checking a torque wrench setting.
Divide the value in newton-metres by 1.355817948, or multiply by 0.737562. One newton-metre is about 0.7376 foot-pounds.
One foot-pound equals twelve inch-pounds, because a foot is twelve inches. Multiply foot-pounds by 12 to get inch-pounds.
It is a metric gravitational unit of torque. One kgf·m equals 9.80665 newton-metres.
No. They share the unit newton-metre, but torque is a turning effect about an axis while energy is work done along a line.
