N to lbf Converter

How to convert newtons to pound-force

1 lbf = 4.4482216152605 N exactly. Divide newtons by 4.4482216152605 to get pound-force; multiply lbf by the same factor to get newtons.

A force of 100 N is approximately 22.480894 lbf. The newton is the SI unit of force; pound-force is a non-SI force unit. The exact relationship keeps reverse conversions consistent even when the displayed result is rounded.

Paste N, newton, newtons, lbf, pound-force or pound force after a value to select the direction automatically. A bare number uses the selected source unit, and Swap carries the unrounded result into the other direction.

Do not use lb, lbs, lbm or pounds here. Those commonly describe mass, while lbf describes force. This converter deliberately rejects mass-unit suffixes instead of silently treating them as pound-force.

Values use the same exact factor as the calculator and are displayed to six decimal places where needed.

Input and rounding

Use a decimal point, a fraction such as 1/2, or a mixed number such as 1 1/2. Properly grouped thousands commas are accepted. Negative measurements, unrecognized units and incomplete numbers need to be corrected before copying. Clearing the input also clears the previous answer.

Decimal places controls display rounding, not the accuracy of your original measurement. Swap uses the underlying result rather than the rounded text. Inputs and outputs must be finite, nonnegative and no larger than one trillion. Very small positive values use scientific notation instead of being displayed as zero.
