Torque is measured in units such as N·m, ft·lb, in·lb, kgf·m. Pick a source and target unit above, enter a value, and the result appears instantly — free and entirely in your browser. Below you'll find the most common individual conversions as dedicated pages.
Which torque units are there?
- Newton-metre (N·m) — The newton-metre (N·m) is the SI unit of torque: one newton of force applied one metre from the pivot. It is the standard for tightening specifications in Europe.
- Pound-foot (ft·lb) — The pound-foot (ft·lb, or lb·ft) is the imperial torque unit: one pound of force at one foot. It is standard in the US and equals about 1.356 N·m.
- Pound-inch (in·lb) — The pound-inch (in·lb) is one pound of force at one inch — a twelfth of a pound-foot. It is used for small fasteners and electronics, about 0.113 N·m.
- Kilogram-force metre (kgf·m) — The kilogram-force metre (kgf·m) is an older metric torque unit equal to exactly 9.80665 N·m. It still appears in some motorcycle and machinery specifications.
Key facts about torque
Torque is rotational force. Europe uses newton-metres (N·m), the US uses pound-feet (ft·lb) and pound-inches (in·lb), and older specs use kilogram-force metres (kgf·m). Mechanics convert between them constantly.
One newton-metre equals about 0.7376 pound-feet (ft·lb); conversely 1 ft·lb = 1.3558 N·m. Car wheel bolts are typically torqued to roughly 110 N·m (about 81 ft·lb).
