Understanding the Relationship Between dBm and Watts

 

dBm and Watts represent the same thing — power — but in different formats. dBm is logarithmic; Watts is linear. Here's how they relate:

📉 dBm is Logarithmic:

• 10 dBm increase = 10x more power

• 20 dBm = 100x more than 0 dBm

🔁 Why Convert?

• Engineers work in dBm, but equipment specs are in Watts.

• Audio systems and transmitters use Watts.

• Wireless devices use dBm to measure signal.

🧮 Formula Reminder:

$$\text{Watts} = 10^{(dBm - 30)/10}$$
