See what a dBm figure is in watts or milliwatts, or the other way around.
| dBm | – |
| W | – |
| mW | – |
Typical for Wi-Fi, radio, and RF notes where power is written in dBm and a datasheet wants watts. Type the power and pick whether it is dBm, W, or mW.
0 dBm is 1 milliwatt. Watts = 0.001 × 10^(dBm/10). Power must stay positive. This is RF power, not loudness in dB SPL.
Value: The power you have — dBm, watts, or milliwatts — matching From.
From: dBm if you have a radio figure; W or mW if you have a linear power.
dBm: Power in decibels relative to 1 mW.
W: Power in watts.
mW: Power in milliwatts.
