Milliwatt [mW] to Kilowatt [kW] Converter

Quick Reference

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

1 Kilowatt (kW) = 1000000 Milliwatt (mW)

How to Convert Milliwatt to Kilowatt

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

To convert Milliwatt to Kilowatt, divide the value by 1000000 (equivalently, multiply by 1.0000e-6). To convert Kilowatt back to Milliwatt, multiply by 1000000.

Example: convert 10 mW to kW:
10 mW = 10 x 1.0000e-6 = 1.0000e-5 kW

↔ Convert Kilowatt to Milliwatt

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

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 [mW] to Kilowatt [kW] Converter

What is 1 mW in kW?
1 Milliwatt (mW) equals 0.000001 kW, and 1 kW equals 1,000,000 mW.
How do I convert Milliwatt to Kilowatt?
Divide by 1,000,000: 10 mW ÷ 1,000,000 = 0.00001 kW. The converter above does it for any value, with the precision you choose.
What is 100 mW in kW?
100 mW = 0.0001 kW. Common amounts are listed on this page, each with its own step-by-step page.
Is a Milliwatt bigger than a Kilowatt?
No. 1 mW is only 0.000001 kW: it takes 1,000,000 mW to make 1 kW.
