How to Convert Milliwatt to Foot-pound per Second
- 1 mW = 0.0007375621493 ft·lbf/s
- 1 ft·lbf/s = 1355.817948 mW
- Example: convert 15 mW to ft·lbf/s: 15 mW = 15 × 0.0007375621493 ft·lbf/s = 0.01106343224 ft·lbf/s
Formula
ft·lbf/s = mW × 0.0007375621492773
or ft·lbf/s = mW ÷ 1355.817948331
Derivation from SI units:
- 1 mW = 10⁻³ W
- 1 ft·lbf/s = 1.3558179483314 W
- 1 mW = 0.001 W ÷ 1.355817948331 W per ft·lbf/s = 0.0007375621492773 ft·lbf/s
Both units are defined exactly, so the factor is exact. Milliwatt definition: milliwatt; Foot-pound per Second definition: foot-pound per second.
Worked examples
- A reading of 10 mW converts to 0.007375621493 ft·lbf/s.
10 mW × 0.0007375621493 = 0.007375621493 ft·lbf/s - A value of 200 mW is 0.1475124299 ft·lbf/s.
200 mW × 0.0007375621493 = 0.1475124299 ft·lbf/s

Frequently asked questions
How many foot-pounds per second are in 1 milliwatt?
1 mW = 0.0007375621493 ft·lbf/s.
How do I convert milliwatts to foot-pounds per second?
Multiply the value in mW by 0.0007375621493, or divide it by 1355.817948. For example, 15 mW × 0.0007375621493 = 0.01106343224 ft·lbf/s.
Is the mW to ft·lbf/s conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
