watt's vs amp's

[Hellfighter]

i have a unit it use 300w need to know how much that is in amps? to get an off & on switch for it to add to the housing of the unit, it never had one

300w = ____ amps?

lable on it says 300 watts
don't list amps

For your outlet?

U * I = P

P = Watt

I = Amps

U = Voltage


I = P / U

So if your outlet is 230v (which it is in Europe) and your appliance use 300 watts = 300 / 230 = 0,77 A

Lower voltage (V) = Higher Current (A)

Hope that helps

But if it is between an outlet and something you should always use a switch rated at the same rating as the fuse of the outlet, so always use a switch that has the same rating as the fuse before it

thanks, its 110v
like to add it to the housing of the united so it has a off and on switch to it, other wise i have to unplug it all the time

some switchs made for amp and not listed as how much watts they can handle reason for asking
