> Sure, and 10db means "10x more power". But: 1. 10x more power than what? It changes, and you Just Have to Know.

That gives me an idea - explicitly state the basis and multiply. So the current notation "3 dBm" should instead be "1 mW × 3 dB".

Furthermore, any addition in the logarithmic domain must be grouped, like: "3 dBm + 5 dB" --> "1 mW × (3 dB + 5 dB)".
