A real-time conversion tool for torque (rotational force) units, supporting Newton-meter (N·m), kilogram-force meter (kgf·m), pound-force foot (lb·ft), and pound-force inch (lb·in). Includes common mechanical references such as spark plugs and wheel lug nut torque standards.
How to use
- Enter a value into any of the torque unit input fields.
- The values will immediately sync and update across all other units.
- Refer to the common presets at the bottom to quickly load typical values.
FAQ
- How many Newton-meters are in one kgf·m?
- One kilogram-force meter (kgf·m) is equal to approximately 9.80665 Newton-meters (N·m) under standard Earth gravity.
- Why is correct wheel lug nut torque important?
- Under-tightened lug nuts can come loose while driving, while over-tightening can stretch and damage the wheel studs or crack the alloy wheel. Always follow your car's specified manual torque (typically 100-120 N·m for passenger cars).
