Horsepower (hp) to Milliwatt (mW) Conversion
The conversion from horsepower (hp) to milliwatt (mW) involves a transformation from traditional mechanical power units to micro-power electronic device units. This conversion spans an enormous range from large machinery and engines to ultra-low power electronic components and sensors. Horsepower is commonly used to describe the power of engines, motors, and large mechanical equipment, while milliwatts are used for micro-electronic devices, sensors, and low-power circuits.
This tool provides professional hp to mW conversion functionality, supporting high-precision calculations and real-time conversion, suitable for engineers working across different scales of power systems, from automotive and industrial applications to IoT and electronic device design.
Conversion Formula
The conversion between horsepower (hp) and milliwatt (mW) involves a large scale difference:
Basic Formula:
