How to Convert dBm to Watts
Converting dBm to watts is essential in RF and wireless communications. dBm is a logarithmic unit referenced to 1 milliwatt.
The formula is: Watts = 10^((dBm - 30) / 10). For example, 30 dBm = 1 watt. This logarithmic scale makes it easier to work with very large and very small power levels.
Common reference: 0 dBm = 1 mW, 30 dBm = 1 W, 60 dBm = 1 kW.
Quick Tips
- 1 mile = 1.609 km (miles are bigger)
- 1 kg = 2.205 lbs (roughly double + 10%)
- Temperature: (°F - 32) × 5/9 = °C
