The working
The factor below is an exact definition rather than a measurement, so nothing is approximated in the arithmetic. The only rounding on this page happens where a number is displayed.
1 newton-metre = 0.737562 pound-feet 3 × 0.737562 = 2.21
How much precision do you need?
Each row is the same answer cut at a different number of decimals, with what that choice costs you. Pick the shortest row whose error is smaller than whatever you are measuring with.
| Rounded to | Answer (lb-ft) | Off by |
|---|---|---|
| Whole number | 2 | −0.21269 |
| 1 decimal | 2.2 | −0.01269 |
| 2 decimals | 2.21 | −0.00269 |
Round trip: take 2.21 lb-ft back the other way and you land on 2.9964 N·m — a drift of 0.0036 N·m. That gap is the rounding, not the conversion.
