Question about units for Signal Strength: dBm vs mW

I know I have to look at relative changes when I compare signal strength of two different distances while using dBm. But if I convert it to mW, can I look at the absolute values and compare them generally(like we compare two different values for Joules, for example)?

Here's why I need it: I'm looking at Wi-Fi and trying to use it to compare the intensity at different distances. dBm would be very tedious to use, so if I could convert these values to mW and then look at the relationship much more intuitively, that would help much more.
