About this conversion
This page converts milliwatts (mW) into watts (W), two units used to describe power, the rate at which energy is transferred or work is done.
A milliwatt is 0.001 watt units.
The watt is the SI unit of power, equal to one joule per second.
The formula is W = mW × 0.001, derived from each unit's fixed relationship to the watt, the SI unit of power.
Because both units are defined by exact numeric relationships to the watt, this conversion is exact rather than approximate.
