dBm (decibel-milliwatts) is a unit of power measurement relative to 1 milliwatt. Converting dBm to milliwatts provides an absolute power value that's useful in various telecommunications and electronics applications.
The calculator uses the conversion formula:
Where:
Explanation: The formula converts logarithmic dBm values to linear milliwatt values using exponential calculation.
Details: Accurate power conversion is essential in RF engineering, telecommunications, network design, and signal strength measurements to understand actual power levels in linear terms.
Tips: Enter the dBm value you want to convert. The calculator will provide the equivalent power in milliwatts. Both positive and negative dBm values are supported.
Q1: What does 0 dBm represent?
A: 0 dBm equals exactly 1 milliwatt (1 mW) of power.
Q2: How do negative dBm values convert?
A: Negative dBm values convert to fractional milliwatt values (e.g., -10 dBm = 0.1 mW).
Q3: Why use dBm instead of milliwatts?
A: dBm provides a logarithmic scale that's more convenient for expressing very large or very small power values and simplifies calculations involving gains and losses.
Q4: What are common dBm values in telecommunications?
A: Typical values range from -120 dBm (very weak signal) to +30 dBm (strong transmitter output).
Q5: Can this calculator handle decimal dBm values?
A: Yes, the calculator supports decimal values for precise conversions.
