PS (Metric Horsepower) to mW (Milliwatt) Conversion
PS (metric horsepower) to mW (milliwatt) conversion is an important unit conversion for small power device applications. Milliwatt (mW), as a thousandth of a watt power unit, is mainly used in precision instruments, electronic components, sensors, micro devices and other small power scenarios. This tool provides precise PS to mW conversion functionality, supporting power unit conversion needs in electronics engineering, precision instrumentation, micro devices and other fields.
Conversion Formula
Basic Conversion Relationship
PS to mW Conversion:
- 1 PS = 735,500 mW
- mW = PS × 735,500
mW to PS Conversion:
- 1 mW = 0.00000136 PS
- PS = mW × 0.00000136
Detailed Calculation Process
Physical Definition:
- 1 PS = 75 kg·m/s = 735.5 W = 735,500 mW
- 1 mW = 0.001 W = 0.001 ÷ 735.5 PS = 0.00000136 PS
Conversion Steps:
- PS → W: PS value × 735.5
- W → mW: W value × 1000
- Direct conversion: PS value × 735,500 = mW value
