dBm (decibel-milliwatts) is a logarithmic measurement of power relative to 1 milliwatt. Converting dBm to milliwatts provides an absolute power value, which is often needed for generator specifications and power calculations.
The calculator uses the conversion formula:
Where:
Explanation: The formula converts from logarithmic scale (dBm) to linear scale (mW) by raising 10 to the power of dBm divided by 10.
Details: Accurate power conversion is essential for generator specifications, RF engineering, and telecommunications where precise power measurements are critical.
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 in mW?
A: 0 dBm equals exactly 1 milliwatt (mW), as it's the reference point for dBm measurements.
Q2: How many mW is 10 dBm?
A: 10 dBm equals 10 mW (10^(10/10) = 10^1 = 10 mW).
Q3: What's the advantage of using dBm instead of mW?
A: dBm allows expressing very large and very small power values in a compact form and makes multiplication/division calculations into simple addition/subtraction.
Q4: What is -30 dBm in mW?
A: -30 dBm equals 0.001 mW (10^(-30/10) = 10^-3 = 0.001 mW or 1 μW).
Q5: When would I need this conversion for generators?
A: When working with RF generators or signal generators where output power is often specified in dBm but system components may require mW values.
