Man I usually calculate that in my head.
That's actually a dBW calculator. dB's relative to a 1 Watt reference level. Just like dBm is dB's relatave to a 1 milliwatt reference. Do it in your head. Doubling or halving is a 3 dB change. 10x is a 10 db change.
With the one watt reference, 2 Watts would be 3 dB, 4 Watts would be 6 dB, 8 Watts would be 9 dB. 10 Watts would be 10 dB and therefore 5 Watts would be 7 dB. No calculator required.
