No device uses "kilowatts per hour". A watt or kilowatt is a unit of power, not of energy. That means that the "per hour" or "per second" is already implied - the watt refers to a "rate of energy conversion" - not to an amount of energy. If a devices uses a certain amount of kilowatts, it uses this amount all the time while it is on - whether it is kept on for a second or for several days.

Why does a ping pong float with a hair dryer?
When you point a running hair dryer upward, and place a ping pong ball in the air stream, it will eventually float somewhere above the hair dryer and near the air stream. It stays above the dryer because the drag of the air balances out the ball's 2.7 grams of mass, and near the air stream due to the Bernoulli effect. The Bernoulli effect is the drop in pressure when a fluid's velocity increases; you can demonstrate it by blowing over the top of a piece of paper. It is partly responsible for the lift generated by an airplane's wing. The ball is drawn towards the center of the air stream due to the increasing velocity and the resulting Bernoulli force, but is pushed away by the air glancing off its surface. The ball maintains a position where these forces balance out, perhaps wobbling back and forth so the average forces balance out.

How much does it cost to use a hair dryer for 30 minutes?
The price of electricity is usually quoted per kilowatt-hour. If your hair dryer uses 2,000 watts for 30 minutes, that is one kilowatt-hour.So take the wattage rating of your hair dryer and divide by 1000 to get kilowatts. You specified 30 minutes, which is 0.5 hours; multiply the kilowatts by the hours to get kilowatt-hours. Then multiply the price per kilowatt-hour of your electricity to get the total cost.For example: 1500-watt hair dryer for 30 minutes at $0.12/kW-h1500 watts ÷ 1000 = 1.5 kilowatts30 minutes = 0.5 hours1.5 kilowatts x 0.5 hours = 0.75 kW-h0.75 kW-h x $0.12/kW-h = $0.09
