• Example:
  
  • 1W = 1000 mW
  • 23 dBm = 200 mW = 0.2 W
  • 24 dBm = 250 mW = 0.25 W
  • 30 dBm = 1 W
  • 37 dBm = 5 W

• Watt to dBm formula：\[ \text{dBm} = 10 \cdot \log_{10}(Watt \times 1000) \]
  • input Watt：
  • calculation：
  • Result：


• dBm to W formula：\[ \text{Watt} = 10^{(\text{dBm} / 10)} / 1000 \]
  • input dBm：
  • calculation：
  • Result：
