Milliwatts to Kilowatts Conversion Calculator

Milliwatts to Kilowatts Calculator

Enter power in milliwatts:

Result in kilowatts: kW

A milliwatts to kilowatts calculator converts power measurements between extremely small (mW) and large (kW) scales. This conversion is useful for:
✅ Energy monitoring (comparing microelectronics to grid power)
✅ Telecommunications (transmitter power vs station consumption)
✅ Scientific research (laser power measurements)
✅ Power efficiency calculations

Conversion Formulas

1. Milliwatts to Kilowatts

$$P(kW)=\frac{P(mW)}{1,000,000}$$

Example:

• Convert 2,500 mW to kW:

  $$2,500÷1,000,000=0.0025\text{ kW}$$

2. Kilowatts to Milliwatts

$$P(mW)=P(kW)\times 1,000,000$$

Example:

• Convert 0.075 kW to mW:

  $$0.075\times 1,000,000=75,000\text{ mW}$$

Conversion Table (mW ⇆ kW)

Milliwatts (mW)	Kilowatts (kW)
1 mW	0.000001 kW
10 mW	0.00001 kW
100 mW	0.0001 kW
1,000 mW	0.001 kW
10,000 mW	0.01 kW
100,000 mW	0.1 kW
1,000,000 mW	1 kW

How to Use the Calculator

1. Enter mW → Get kW (Divide by 1,000,000)

2. Enter kW → Get mW (Multiply by 1,000,000)

Example Calculations:

• 50,000 mW to kW:

  $$50,000÷1,000,000=0.05\text{ kW}$$

• 1.2 kW to mW:

  $$1.2\times 1,000,000=1,200,000\text{ mW}$$

Practical Applications

• Solar Panels: A 5 kW system = 5,000,000 mW

• Bluetooth Device: 2.5 mW = 0.0000025 kW

• Industrial Laser: 50,000 mW = 0.05 kW
