So I have some items that consume 186 watts per hour.

I know that mains electricity in the UK is rated at 230v, so how do I work out how many amps/hour my items consume?

I was thinking, 186 divided by 230 = 0.80 amps. Is this correct?

What is your kw cost ?

Think mines between 13p-16p.

So at 13p for 1 hour it would be 2 pence.

Watts x hours divide by 1000 x pence per kw
