Press Calculate after the entries are in.

What this power conversion is for

Use this page when a measurement is written in kilowatts and the next step needs milliwatts. The number stays blank until you press Calculate, so a half-typed entry is never mistaken for the answer.

The factor

Multiply by the factor: 1 kilowatt = 1,000,000 milliwatts.

A worked example

10 kilowatts are 1e+07 milliwatts. Multiply the result by the reverse factor if you want the original number back.

How to check it

Write the factor down, do the multiply on paper, and compare it with the result card. If you change a sentence on this page, edit the HTML file and reload. The form and this note live in the same file.

The reverse conversion is milliwatts to kilowatts. A nearby pair in the same units is BTU per hour to milliwatts. When the converted number is the input to a job, continue with the wattage.
