Error vector magnitude
EVM is a "magnitude," by definition not a power. EVM in dB is a power ratio. RMS power is at best ambiguous and at worst meaningless: power can be found from magnitude by taking the Mean Square value, but Root Mean Square value just yields another magnitude.

Minimum detectable signal
kT units are Watts. You would have to do 10*log10(kT) to get it in dBW. Similarly, 1000*kT is in milliWatts. 10*log10(1000*kT) = 30+10*log10(kT) is in dBm.
