Precision unit conversion
These three engineering units are grouped together because they're the ones DIYers, mechanics and electronics hobbyists tend to need side by side — torque wrench settings, motor specs and clock speeds.
| Convert | Result |
|---|---|
| 1 newton (N) | 0.224809 lbf |
| 1 pound-force (lbf) | 4.44822 N |
| 1 kilogram-force (kgf) | 9.80665 N |
Torque wrench settings for wheel nuts, engine bolts and household fittings are frequently given in either newton-metres or pound-feet depending on where the manual, car or tool was made — a common source of over- or under-tightening if you use the wrong scale.

Multiply Nm by 0.737562. So a spec of 100 Nm is about 73.76 lb-ft — always double-check which unit your torque wrench and the manufacturer's spec sheet are using before tightening anything structural.
One revolution per minute is 1/60 Hz, or about 0.01667 Hz — a motor spinning at 3,000 RPM is running at 50 Hz.
Multiply newtons by 0.224809. So 500 N is about 112.4 lbf.
