How to use this Milliwatts to Decibel-milliwatts Converter 🤔

Follow these steps to convert given power from the units of Milliwatts to the units of Decibel-milliwatts.

1. Enter the input Milliwatts value in the text field.
2. The calculator converts the given Milliwatts into Decibel-milliwatts in realtime ⌚ using the conversion formula, and displays under the Decibel-milliwatts label. You do not need to click any button. If the input changes, Decibel-milliwatts value is re-calculated, just like that.
3. You may copy the resulting Decibel-milliwatts value using the Copy button.
4. To view a detailed step by step calculation of the conversion, click on the View Calculation button.
5. You can also reset the input by clicking on Reset button present below the input field.

What is the Formula to convert Milliwatts to Decibel-milliwatts?

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

Power_{(Decibel-milliwatts)} = 10 × Math.log(Power_(Milliwatts)) × Math.LOG10E

Substitute the given value of power in milliwatts, i.e., Power_(Milliwatts) in the above formula and simplify the right-hand side value. The resulting value is the power in decibel-milliwatts, i.e., Power_{(Decibel-milliwatts)}.

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:

The power in milliwatts is:

Power_(Milliwatts) = 500

Formula:

The formula to convert power from milliwatts to decibel-milliwatts is:

Power_{(Decibel-milliwatts)} = 10 × Math.log(Power_(Milliwatts)) × Math.LOG10E

Substitution:

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

Power_{(Decibel-milliwatts)} = 10 × Math.log(500) × Math.LOG10E

Power_{(Decibel-milliwatts)} = 26.9897

Final Answer:

Therefore, 500 mW is equal to 26.9897 dBm.

The power is 26.9897 dBm, in decibel-milliwatts.

2

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

Answer:

Given:

The power in milliwatts is:

Power_(Milliwatts) = 200

Formula:

The formula to convert power from milliwatts to decibel-milliwatts is:

Power_{(Decibel-milliwatts)} = 10 × Math.log(Power_(Milliwatts)) × Math.LOG10E

Substitution:

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

Power_{(Decibel-milliwatts)} = 10 × Math.log(200) × Math.LOG10E

Power_{(Decibel-milliwatts)} = 23.0103

Final Answer:

Therefore, 200 mW is equal to 23.0103 dBm.

The power is 23.0103 dBm, in decibel-milliwatts.

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.
