Kilowatt [kW] to Milliwatt [mW] Converter

Quick Reference

1 Kilowatt (kW) = 1000000 Milliwatt (mW)

1 Milliwatt (mW) = 1.0000e-6 Kilowatt (kW)

How to Convert Kilowatt to Milliwatt

1 kW = 1000000 mW
1 mW = 1.0000e-6 kW

To convert Kilowatt to Milliwatt, multiply the value by 1000000. To convert Milliwatt back to Kilowatt, divide by 1000000.

Example: convert 10 kW to mW:
10 kW = 10 x 1000000 = 10000000 mW

↔ Convert Milliwatt to Kilowatt

Kilowatt

Definition: A kilowatt (kW) is a unit of power equal to one thousand (10³) watts. It is a multiple of the base unit, the watt, in the International System of Units (SI).

History/origin: The watt is named in honor of Scottish inventor James Watt. The kilowatt, as a decimal multiple of the watt, was derived as a larger unit for measuring significant amounts of power.

Current use: Kilowatts are used to measure the power consumption of appliances, electric motors, and industrial equipment. It is also used to measure the power output of generators and engines.

Milliwatt

Definition: A milliwatt (mW) is a unit of power equal to one thousandth (10⁻³) of a watt. It is a subunit of the base unit, the watt, in the International System of Units (SI).

History/origin: The watt is named in honor of Scottish inventor James Watt. The milliwatt, as a decimal multiple of the watt, was naturally derived as a smaller, more convenient unit for measuring smaller powers.

Current use: Milliwatts are used to measure small power levels in electronic circuits, audio equipment, and wireless communication devices. It's used where power consumption is low.

Kilowatt [kW] to Milliwatt [mW] Converter

What is 1 kW in mW?
1 Kilowatt (kW) equals 1,000,000 mW, and 1 mW equals 0.000001 kW.
How do I convert Kilowatt to Milliwatt?
Multiply by 1,000,000: 10 kW × 1,000,000 = 10,000,000 mW. The converter above does it for any value, with the precision you choose.
What is 100 kW in mW?
100 kW = 100,000,000 mW. Common amounts are listed on this page, each with its own step-by-step page.
Is a Kilowatt bigger than a Milliwatt?
Yes. 1 kW = 1,000,000 mW, so the same quantity becomes a larger number when written in mW.
