- Read the result. Select Convert to open a page for this value, or use the table below.
Definitions and assumptions
Torque factors are expressed relative to newton metres. Pound-force and kilogram-force terms use their conventional force definitions. Torque is a rotational moment, not a substitute label for energy.
Frequently asked questions
how many N·m is 1 ft·lb?
1 Foot-pound force ≈ 1.35581795 Newton metres. Auto mode preserves significant digits for small values; manual mode rounds to the selected decimal places. ≈ means approximate; < means below the display limit. Extreme values use × 10ⁿ. Calculations are rounded only for display.
how to convert ft·lb to N·m?
The calculator converts the input to the category's reference unit, then divides by the target unit's factor. 1 × 1.35581794833 ≈ 1.35581795 Newton metres. Use the source and target factors shown in the formula. The worked example uses the value on this page, and the table provides other common values.
Is a newton metre always the same as a joule?
They have the same dimensions, but describe different quantities. This tool converts torque units; interpreting mechanical work also requires the rotation angle.
Why is the displayed result rounded?
Auto mode preserves significant digits for small values; manual mode rounds to the selected decimal places. ≈ means approximate; < means below the display limit. Extreme values use × 10ⁿ. Calculations are rounded only for display.
What input range can I use?
This calculator accepts non-negative values up to 1 trillion, with up to 8 decimal places. It does not calculate signed vectors or calendar date intervals.
Why is a unit unavailable?
A conversion is unavailable when a verified unit definition or a current exchange-rate value has not been configured. The tool does not invent a coefficient.
