Typical home energy cost is 10 cents per kilowatt hour
A 60 watt bulb running for one hour uses 60 watt hours
.10 X (60/1000) = .006 cents per hour

Watt hour is a measurement of energy use, something that's pulling one watt during one hour. Tera is a multiplier, 1x10^18, so it's either something pulling one watt for that many hours, or it's something pulling that many watts for one hour or something inbetween.
It depends what the power rating of the appliance is. A 500 watt microwave will use half a kilowatt if it's run for an hour on full power. A 750 watt unit will use 3/4 of a unit in the same time period.
cooling capacty one ton is how much watts
It is a unit of energy. If energy is transferred at a rate (power) of one kilowatt, during one hour, then one kilowatt-hour (kilowatt times hour) of energy will be transferred. Since a joule is equal to a watt-second, a kilowatt-hour is the same as 3.6 million joules.
