# dBm to uW (microwatt) Formula and Calculator

Use this calculator to convert dBm (deciBel referenced to 1 milliwatt) to μW (Microwatt).

🔁 μW to dBm

## Formula

PuW = (10PdBm/10)*103

where

• PuW is the power in microwatt
• PdBm is the power in dBm

## Example Calculations

• 0 dBm power is equivalent to 1000 microwatt
• -10 dBm power is equivalent to 10 microwatt

## Background

dBm (decibel-milliwatts) is a unit of power measurement that expresses the power level in decibels relative to 1 milliwatt (mW). It is commonly used in telecommunications, radio, and audio engineering to measure the power of signals.

• Reference Point: dBm is referenced to 1 milliwatt (mW). This means 0 dBm is equal to 1 mW of power.
• Logarithmic Scale: The dBm scale is logarithmic, making it convenient to represent a wide range of power levels. A logarithmic scale is useful because it compresses large ranges of values into a more manageable form.

A Microwatt (µW) is a unit of power equal to one millionth of a watt (W). It is commonly used to measure very small amounts of power, particularly in fields such as electronics, telecommunications, and medical devices.

A microwatt (µW) is a unit of power equal to one millionth of a watt. It is commonly used to measure very small amounts of power, especially in applications involving low-power electronics, sensors, and communication devices.
