Torque Unit Converter
Convert a known torque value between N·m, ft-lb, in-lb, N·cm, N·mm, kgf·cm, and kgf·m. Built for workshop specs, torque-wrench displays, repair manuals, and parts sheets.
How It Works
Formula
Variables, symbols and units
- Input torque value
- Converted torque
- N·m factor of the source unit(N·m)
- N·m factor of the target unit(N·m)
Calculation method explained
The calculator uses N·m as the canonical base unit. Your input value is multiplied by the source-unit factor to get N·m, then divided by the target-unit factor. The result is a fixed unit conversion trail, not torque advice or a live product database lookup.
Reference factors used by the calculator (N·m per unit):
- 1 N·m = 1 N·m
- 1 ft-lb = 1.355817948331 N·m
- 1 in-lb = 0.112984829028 N·m
- 1 N·cm = 0.01 N·m
- 1 N·mm = 0.001 N·m
- 1 kgf·cm = 0.0980665 N·m
- 1 kgf·m = 9.80665 N·m
The secondary result row shows the exact source -> N·m -> target trail and the specific factors used for that conversion.
Frequently Asked Questions
How does this torque unit converter work?
Every supported unit is defined as a fixed number of newton-meters. The calculator multiplies your source value into N·m first, then divides by the target-unit factor. The result panel also shows the exact source -> N·m -> target trail so you can sanity-check the conversion.
Where do N·m, ft-lb, and in-lb usually show up?
N·m is common on modern repair manuals and many digital torque tools. ft-lb is common on imperial torque wrenches and automotive references. in-lb is common on smaller fasteners, clamps, bike parts, and lower-range tools.
Why are N·cm, N·mm, kgf·cm, and kgf·m included?
They cover the smaller-scale and legacy-style torque specs people still meet in workshop documents, bike service notes, and older tool charts. The calculator keeps them on the same N·m base so every supported unit uses one auditable model.
Is this about an automotive torque converter part?
No. This page converts torque measurement units only. It does not explain, diagnose, or compare drivetrain torque converter components.
Can this tell me the correct torque for a vehicle, bike, appliance, or fastener?
No. This tool converts one known torque value into another unit only. It does not recommend torque settings, confirm wrench calibration, choose fasteners, certify compliance, or decide whether a spec is safe.
