### Watt to mW, kW, MW, GW, dBm, dBW conversion calculator:

Just type the value at one field and press the calculate button to get all the watt conversion.

### How to convert watts to nano Watts (nW)

The power P in nanowatts (nW) is equal to the power P in watts (W) divided by 10 to the power minus 9:

*P*_{(nW)} = *P*_{(W)} / 10^{-9}

By reversing,

1 nW = 0.000000001 W

**Example:** Radio and Radar receivers

### How to convert watts to microwatts (µW)

The microwatt is equal to the watt divided by 10 to the power minus 6

*P*_{(µW)} = *P*_{(W)} ⋅ 10^{-6}

1 µW = 0.000001 W

**Example:** Integrated Circuits

### How to convert watts to milliwatts (mW)

The milliwatt is equal to the watt divided by 10 to the power minus 3

*P*_{(mW)} = *P*_{(W)} ⋅ 10^{-3}

1 mW = 0.001 W

**Example:** Smart Phone

### How to convert watts to kilowatts (kW)

The kilowatt is equal to the watt divided by 10 to the power 3

*P*_{(µW)} = *P*_{(W)} ⋅ 10^{3}

1 kW = 1000 W

Example: Motors, drier, grinder

### How to convert watts to Megawatts (MW)

The kilowatt is equal to the watt divided by 10 to the power 6

*P*_{(µW)} = *P*_{(W)} ⋅ 10^{6}

1 MW = 1000000 W

**Example:** Turbo Alternator

### How to convert watts to Giga-watts (GW)

The gigawatt is equal to the watt divided by 10 to the power 6

*P*_{(GW)} = *P*_{(W)} ⋅ 10^{9}

1 GW = 1000000000 W

**Example:** Transmission Lines

### How to convert watts to dBW

The power P in decibel-milliwatts (dBW) is equal to 10 times base 10 logarithms of the power P in watts (W) divided by 1 watt:

*P*_{(dBW)} = 10 ⋅ log_{10}( *P*_{(W)} / 1W)

**Example:** Fibre-optic communication cables
