Watts to KwH

[Diceman719]

What does using a 1500W space heater in my TT mean in Kilowatt Hours?
(I'm paying .xx per Kilowatt Hour, so am trying to wrap my head around what this space heater will cost me to run...)

You basically answered your own question....

1 kilowatt hour is equal to 1 kilowatt of energy used for one hour.

Your heater is 1500 watts or 1.5 killwatts.

So for one hour, you use 1.5kw at 10 cents per kw per hour and it would cost you 15 cents to run the heater at max setting.

This link is a little more in depth on how to calculate over say a year...

Thanks, Larry!

(That's what I thought, but couldn't get a straight answer from the folks nearby on how a watt draw was calculated as to KwH...)

If an appliance or tool doesn't show watts on the label and you want to know how many watts is it....take the voltage times its rated amps....

A heater rated 10 amps at 120 volts would be 1200 watt heater.
