Formula

The formula to convert given power from Milliwatts to Decibel-milliwatts is:

Power(Decibel-milliwatts) = 10 × Math.log(Power(Milliwatts)) × Math.LOG10E

Calculation

Calculation will be done after you enter a valid input.

Examples

1

Consider that a mobile phone consumes 500 milliwatts (mW) of power while in standby mode.
Convert this power consumption from milliwatts to Decibel-milliwatts.

Answer

Given:

Power in Milliwatts = 500 mW

Converting Power from Milliwatts to Decibel-milliwatts...

The formula to convert from Milliwatts to Decibel-milliwatts is:

Power(Decibel-milliwatts) = 10 × Math.log(Power(Milliwatts)) × Math.LOG10E

Substitute given Power(Milliwatts) = 500 in the above formula.

Power(Decibel-milliwatts) = 10 × Math.log(500) × Math.LOG10E

Power(Decibel-milliwatts) = 26.9897

Therefore, 500 mW is equal to 26.9897 dBm.

2

Consider that a smartwatch operates on 200 milliwatts (mW) of power.
Convert this power usage from milliwatts to Decibel-milliwatts.

Answer

Given:

Power in Milliwatts = 200 mW

Converting Power from Milliwatts to Decibel-milliwatts...

The formula to convert from Milliwatts to Decibel-milliwatts is:

Power(Decibel-milliwatts) = 10 × Math.log(Power(Milliwatts)) × Math.LOG10E

Substitute given Power(Milliwatts) = 200 in the above formula.

Power(Decibel-milliwatts) = 10 × Math.log(200) × Math.LOG10E

Power(Decibel-milliwatts) = 23.0103

Therefore, 200 mW is equal to 23.0103 dBm.

Milliwatts

A milliwatt (mW) is a unit of power equal to one thousandth of a watt. It is often used in contexts where power levels are low, such as in electronics and communications.

Decibel-milliwatts

A decibel milliwatt (dBm) is a unit of power level used in radio, microwave, and fiber-optic communication networks. It is a logarithmic unit that expresses power relative to one milliwatt.
