My drone's motor mount screws are specced at 0.8 N·m, but my precision screwdriver only shows in·lb. What setting do I use?

0.8 N·m × 8.8507 ≈ 7.1 in·lb. Set the screwdriver to about 7 in·lb — overtightening small screws like these can strip the threads in plastic or aluminum housings.

A spec sheet lists 3 N·m for a sensor housing bolt. That seems too small to matter — does it really need a torque wrench?

3 N·m ≈ 26.6 in·lb. If the specification lists a torque, set a torque tool to that value.

Why does my engine manual list head bolts in N·m but spark plugs in a much smaller number that looks like it could be in·lb?

A spark plug value in in·lb would be larger than in N·m (20 N·m ≈ 177 in·lb). If a value looks wrong, check the unit label before tightening.

1 Newton-Meter = 8.8507 Inch-Pound

Key Formulas

Newton-Meter → Foot-Pound

ft·lb = N·m × 0.737562

Foot-Pound → Newton-Meter

N·m = ft·lb × 1.35582

Newton-Meter → Inch-Pound

in·lb = N·m × 8.85075

Inch-Pound → Newton-Meter

N·m = in·lb × 0.112985

Formula

in·lb = N·m × 8.8507457913

Inch-pounds (in·lb) give larger whole numbers than foot-pounds for small torques. When a metric spec sheet gives a value in N·m, this conversion gives the equivalent reading for an inch-pound torque wrench or screwdriver.
