The Torque Converter instantly converts between newton-meters, pound-feet, pound-inches, and kilogram-force meters. Whether you're reading an engine spec or setting a torque wrench to a bolt's tightening value, it gives you the exact figure in one click — and accuracy here is a safety matter.
What Torque Is
Torque is rotational force — the strength of a twist around an axis. It's what an engine produces to turn its crankshaft and what your wrench applies to tighten a bolt. Because it's force acting at a distance from a pivot, its units pair a force with a length: newton-meters, pound-feet, and so on. Different industries and regions favor different pairs, which is where conversion comes in.

Common Torque Conversions
| From | To | Equivalent |
|---|---|---|
| 1 pound-foot | newton-meters | ≈ 1.356 Nm |
| 1 newton-meter | pound-feet | ≈ 0.738 lb-ft |
| 1 kgf-m | newton-meters | ≈ 9.807 Nm |
| 1 pound-foot | pound-inches | 12 lb-in |
Why Getting Bolt Torque Right Matters
This is the practical heart of torque conversion. Fasteners are engineered to a specific tightening value. Under-torque and the joint can work loose — dangerous on a wheel or engine component. Over-torque and you can stretch the bolt, snap it, or strip the thread. When the manual gives a spec in Nm but your wrench reads in lb-ft, converting precisely is what keeps the joint safe and intact.
Torque Is Not Power
A common mix-up: torque and power are different things. Torque is the twisting force; power is how fast work is done. An engine's spec sheet lists both because they describe separate qualities — torque is the shove, power is the sustained output. This tool converts torque units; for power, use a power converter.

Frequently Asked Questions
How do I convert newton-meters to pound-feet?
Divide newton-meters by about 1.356 to get pound-feet, since one pound-foot equals roughly 1.356 Nm. For example, 100 Nm is about 73.8 lb-ft. The converter applies the exact factor instantly.
What is torque?
Torque is a rotational, or twisting, force — how strongly something is turned around an axis. It's what tightens a bolt or turns an engine's crankshaft, and it's measured as force times distance from the pivot, such as newton-meters.
Why does torque conversion matter for cars?
Engine specs and bolt tightening values appear in newton-meters or pound-feet depending on the manufacturer and region. Converting correctly ensures you tighten fasteners to spec, which is critical for safety and to avoid stripping threads or under-torquing.
What units does the converter support?
It handles newton-meters (Nm), pound-feet (lb-ft), pound-inches (lb-in), and kilogram-force meters (kgf-m), covering automotive, mechanical, and engineering needs.
Is torque the same as power?
No. Torque is twisting force, while power is the rate of doing work — they're related but distinct. An engine's torque and horsepower describe different things, which is why specs list both. This tool converts torque units only.
Why is correct bolt torque important?
Fasteners are engineered to be tightened to a specific torque. Too little and a joint can loosen; too much and you can stretch or snap the bolt or strip the thread. Converting the spec to the unit on your wrench prevents both failures.
Is the conversion accurate?
Yes. It uses precise factors at full precision, which matters for safety-critical tightening specifications.
Is this tool free?
Yes — free, instant, and unlimited, with no signup.
