Torque Conversion
Convert torque between lb-ft and newton-meters.
About Torque Conversion
Newton-meters are the metric torque unit, and pound-feet the imperial one, related by the 1.3558 factor. Kilogram-force meters are the engineering-unit variant. Data sheets mix lb-ft, N-m and kgf-m, so converting is essential before comparing torque between cars or specs.
Formula
Torque Conversion
1 lb-ft = 1.3558 N-m; 1 kgf-m = 9.8067 N-m
- pound-feet
- Torque measured in pounds at one foot of lever arm

Assumptions and limits
- The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
How is Torque Conversion calculated?
1 lb-ft = 1.3558 N-m; 1 kgf-m = 9.8067 N-m Newton-meters are the metric torque unit, and pound-feet the imperial one, related by the 1.3558 factor. Kilogram-force meters are the engineering-unit variant.
Why does Torque Conversion matter?
Data sheets mix lb-ft, N-m and kgf-m, so converting is essential before comparing torque between cars or specs.
What values do I need to enter?
This calculator takes 2 inputs: Torque value, Input unit. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
