How to Convert Watts to Milliwatts Using an Easy Conversion Formula

Convert watts to milliwatts with this simple formula:

milliwatts = watts × 1,000

Converting a watt power measurement to a milliwatt measurement involves multiplying your power by the conversion ratio to find the result. A watt is equal to 1,000 milliwatts, so to convert simply multiply by 1,000.

For example:
5 W = (5 × 1,000) = 5,000 mW

Watts and milliwatts are both units used to measure power. Learn more about power and find more power measurement conversion calculators. A watt is a power measurement and can be abbreviated as W, for example 1 W. A milliwatt is a power measurement and can be abbreviated as mW, for example 1 mW.

A watt is equal to the rate of energy of one joule per second and is a standard unit of power measurement under the International System of Units (SI). You might also find our watts to amps calculator or our watts to kilowatt-hours calculator useful.
