📏 Some countries say ‘30 degrees’ and others say ‘86 degrees’ for the same weather! Some say ‘5 km’, others say ‘3 miles’. This tool swaps between them instantly so you always know what it means.
A torque converter lets you switch between units of torque — the rotational equivalent of linear force. The SI unit is the newton-metre (N·m), used in engineering and automotive specifications. Pound-foot (lbf·ft) is common in US automotive, while kilogram-force metre (kgf·m) appears in older European and Asian standards.

❓ Common questions
- What is the difference between N·m and lbf·ft?
- Newton-metre (N·m) is the SI unit of torque; pound-foot (lbf·ft) is the imperial unit. 1 lbf·ft = 1.35582 N·m. Car engine torque specs in the US use lbf·ft; European specs use N·m.
- Why is torque measured in N·m and energy also in joules (which equal N·m)?
- The units are dimensionally the same but conceptually different. Torque is a vector (force × perpendicular distance), while energy (joules) is a scalar. They should not be freely interchanged even though 1 J = 1 N·m.
- What is a dyne-centimetre?
- A dyne-centimetre (dyn·cm) is the CGS unit of torque, equal to 10⁻⁷ N·m. It appears in older physics literature and some precision instrument specifications.
- How do I convert kgf·m to N·m?
- Multiply kgf·m by 9.80665 to get N·m. For example, 10 kgf·m × 9.80665 = 98.07 N·m. This factor comes from standard gravity (9.80665 m/s²).
- What is a typical engine torque?
- A family sedan engine produces roughly 150–300 N·m (110–220 lbf·ft). High-performance sports cars reach 400–700 N·m, and heavy trucks can exceed 2000 N·m.
