This converter turns pound-inches into newton-meters instantly, using the exact factor 1 pound-inch = 0.112984829 newton-meters. Type any number and the result updates as you go — nothing is sent to a server, so the arithmetic happens entirely in your browser.
Used for small fasteners and electronics assembly. The SI unit of torque.
Because the relationship is a simple proportion, one multiplication does the whole job. The table further down gives pre-computed values for the amounts people look up most often, and the result panel also reports the reverse conversion so you can check the figure both ways.
The formula
pound-inches- The amount you are converting, measured in pound-inches
0.112984829- The exact number of newton-meters in one pound-inch
newton-meters- The converted result
How it works, step by step
- Enter the number of pound-inches you want to convert.
- The value is multiplied by 0.112984829, the exact conversion factor.
- The result is displayed in newton-meters, rounded for readability.
- The unrounded value and the reverse conversion appear underneath so you can verify it.
Worked examples
Converting 5 pound-inches
Multiply 5 by 0.11298483. That gives 0.564924 newton-meters. A quick sanity check: one pound-inch is smaller than one newton-meter, so the number should get smaller — and it does.
Converting 72 pound-inches
72 × 0.11298483 = 8.1349 newton-meters. Working backwards, 8.1349 ÷ 0.11298483 returns 72 pound-inches, which confirms the factor is applied the right way round.
How to read your score
Frequently asked questions
How many newton-meters are in one pound-inch?
Exactly 0.112984829. Every conversion on this page is that single number multiplied by your input, so the result carries no rounding error beyond what is shown.
What is the formula to convert pound-inches to newton-meters?
Newton-Meters = pound-inches × 0.112984829. To reverse it, divide instead: pound-inches = newton-meters ÷ 0.112984829, which is the same as multiplying by 8.850745791.
Is the pound-inch bigger than the newton-meter?
No. One pound-inch is only 0.112985 of a newton-meter, so the newton-meter is the larger unit.
Why does my answer differ slightly from other pound-inches to newton-meters converters?
Most differences come from rounding the factor too early. This tool keeps full double precision through the calculation and only rounds at the final display step, and it also shows the unrounded value so you can see exactly where any difference appears.
