Can anyone tell me the whats the watts to amps conversion please?

You can't!

It's like asking how can I convert hours into inches.

Watts / Amps = Volts

Amps x Volts = Watts

Watts / Volts = Amps

Volts / Amps = Ohms

 

[AberdeenAngus]

Watts = Amps x Volts

Assuming you're talking about a bike then volts = 12.

Therefore Watts = Amps x 12

or

Watts / 12 = Amps

a*v=w

so it helps if you know one of the variables, like 12v, or 13.2 if you're OCD.
50w /12v = 4a

Not sure if you're asking the right question Val. I'll assume that you are trying to work out what size fuse to use for a given Wattage. The calculation would be: Watts divided by Voltage = Amps eg. 60W divided by 12V = 5 Amps.
If this is not what you are asking, then I apologise for wittering on.

Easy to remember just like the girls name Ivy Watts (I x V = Watts)

Jeez thats an awful lot of quick replies.... You wouldn't get that response on the gsxr forum

Hell, don't apologise. That's the best thing I've learnt all day.

Thanks guys, just what I needed.

Also bear in mind;if you are trying to work out which fuse to fit,a 5Amp fuse blows at 5Amps so build in a degree of leeway.Ie,a 5Amp circuit should be protected by an 8A or 10A fuse.

Don't forget your battery terminal voltage is 13.2V though.
