How do you convert dBm to Watts?Learn the straightforward method to convert dBm (decibels milliwatt) to watts. Understand the relationship between these units and how to perform accurate conversions for signal strength calculations.
How do you convert dBm to Watts?
To convert decibels milliwatts (dBm) to watts, you can use the following formula:
Watts (W) = 10^((dBm - 30) / 10)
Here's a step-by-step process for converting dBm to watts:
- Subtract 30 from the dBm value.
- Divide the result by 10.
- Raise 10 to the power of the result.
Let's say you have a dBm value of 20 dBm that you want to convert to watts:
W = 10^((20 - 30) / 10)W = 10^((-10) / 10)W = 10^(-1)W = 0.1 watts
So, 20 dBm is equal to 0.1 watts.
This conversion is commonly used in telecommunications and electronics to express power levels.
