The conversion of 33 dBm to watts results in approximately 2.14 watts.
Table of Contents
To convert 33 dBm to watts, the formula used is Watts = 10^((dBm – 30) / 10). This formula translates the decibel-milliwatts into a linear power measurement in watts by adjusting the dBm value relative to 30 dBm, which equals 1 watt, then applying the exponential function. For example, subtract 30 from 33 to get 3, then 10 raised to the power of 3 divided by 10, or 10^(0.3), gives approximately 2.00 watts. So, 33 dBm is about 2.14 watts when rounded to two decimal places.
