How many watts is 2.5 amps?

Excuse me, I'm curious about a particular electrical calculation. Could you please help me understand how many watts correspond to 2.5 amps? I'm trying to wrap my head around the relationship between amperage and wattage, especially in the context of cryptocurrency mining or any other high-powered electrical application. I know it's not a straightforward conversion since it also depends on the voltage, but I'm hoping for a general understanding or perhaps a formula I can use as a starting point. Thank you in advance for your assistance.
