Watts to dBm Conversion Formula

How does this Watts to dBm converter works?

Our DMC RF Conversion Calculator tool uses a straight forward formula to convert Watts to dBm

P(dBm) = 10xlog10(Wattsx1000)

This Watts to dBm formula give an accurate conversion, enabling you to precisely measure signal strength levels in decibel-milliwatts (dBm).

Why use dBm?

Decibel-milliwatts (dBm) gives a compact way to express signal intensity. By referencing power levels to one milliwatt, dBm allows for short representation of both large and small power magnitudes. Whether you’re dealing with minute or substantial power levels, dBm provides a standardized unit for measurement.
