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.

Examples

Translate a known 40 N·m workshop spec into ft-lb before setting a torque wrench.

Converted torque
29.502486 ft-lb
N·m conversion trail
40 N·m -> 40 N·m -> 29.502486 ft-lb; factors: 1 N·m = 1 N·m, 1 ft-lb = 1.355817948331 N·m

The result is smaller because the target torque unit is larger. One target unit contains about 1.36 source units.

Torque units only — this page does not know the correct torque for any vehicle, bike, appliance, or fastener, and it does not certify wrench calibration or safety.

How It Works

Formula

r=v×ffromftor = v \times \dfrac{f_{\text{from}}}{f_{\text{to}}}

Variables

vv

Input torque value

rr

Converted torque

ffromf_{\text{from}}

N·m factor of the source unit(N·m)

ftof_{\text{to}}

N·m factor of the target unit(N·m)

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

01How 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.
02Where 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.
03Why 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.
04Is 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.
05Can 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.
