Torque wrenches are only accurate in the middle of their range, and never use one to loosen a bolt. Read the setting on the tool, not on the chart.
How it works
Torque is a turning force: the same pull on a longer wrench turns a bolt harder, which is why breaker bars work. This page converts between the three torque units mechanics argue about, and turns a torque into the force at the end of a given lever arm.
The formula
Torque = force × lever arm. 1 lb-ft = 1.35582 Nm. 1 kgf-m = 9.80665 Nm. Force = torque ÷ radius.Torque and Force Converter: common questions
- What does the Torque and Force Converter work out?
- Newton-metres, pound-feet and kilogram-force, plus the force a wrench actually applies. It is one of the Unit Converters tools on Mondo Knows.
- How is the Torque and Force Converter calculated?
- Torque is a turning force: the same pull on a longer wrench turns a bolt harder, which is why breaker bars work. This page converts between the three torque units mechanics argue about, and turns a torque into the force at the end of a given lever arm. The maths is short enough to check by hand: Torque = force × lever arm. 1 lb-ft = 1.35582 Nm. 1 kgf-m = 9.80665 Nm. Force = torque ÷ radius.
- Do I need to sign up, and is my data stored?
- No sign-up, and nothing you type is sent anywhere. The calculation runs in your own browser, so the figures stay on your device and the page works offline once loaded.
