My professor asked me to convert following powers into decibels: 15W, 25W, 33W, 450mW, 24MW, 44 GW,120pW. I know that decibels are about ratio power/reference_power. I don't have reference power specified here. Is there something like default value? What should I do?

According to https://en.m.wikipedia.org/wiki/Decibel_watt

dBW is relative to 1 W and dBm is relative to 1 mW. I’d just make sure to provide the correct units, but maybe you could ask your teacher if it matters.
