Use this tool to convert from milliWatt to dBm.
You can select either Milliwatt, Microwatt, Nanowatt or Picowatt.
Formula for mW to dBm
PdBm=10*Log10(PmW)
where
- PdBm is the power in dBm
- PmW is the power in milliwatts
Example Calculations
- 10 milliwatt is equivalent to 10 dBm
- 0.1 milliwatt is equivalent to -10 dBm
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 milliwatt (mW) is a unit of power equal to one thousandth of a watt. It is commonly used to measure small amounts of power, especially in applications involving electronics, telecommunications, and audio engineering.
A milliwatt is a unit of power equal to one thousandth of a watt. It is widely used in various fields to measure small amounts of power, especially in electronics and telecommunications. Understanding milliwatts and their conversion to other units, such as dBm, is essential for accurately describing and comparing power levels in these applications.
