"Kilowatt" is a rate of using energy. It's not an amount of anything.
A 60-watt bulb uses energy at the rate of 60 watts ... the same as 0.06 kilowatts.
In one hour, it uses 60 watt-hours of energy ... the same as 0.06 kilowatt-hours.
1 kilowatt-hour is 1000 watt-hours and 60 watt bulb consume during 1 hour 60 watt-hours of electricity, so then it costs 0.6 cent =>60/1000=0,06*price of 1 kilowatt-hour = 0.6 cent
The bulb uses 7.5 watt-hours each hour, or 90 watt-hours if left on for 12 hours. 1 unit of electricity would be used in 11 days at 12 hours per day.
The amount of electricity a plugged-in lamp uses depends on its wattage. A typical 60-watt bulb, if left on for one hour, uses 0.06 kilowatt-hours of electricity.
A 33 watt fluorescent tube consumes 33 watt-hours of electricity per hour. It means it uses 0.033 kilowatt-hours (kWh) of electricity in one hour.
Using a 7 watt bulb for 1 hour would cost about 0.84 cents based on the average electricity rate in the United States. Over a year, if used for 4 hours a day, it would cost around $12.25 in electricity.

A 75 bulb will use more electricity.
To calculate the cost per hour to use a 150 watt light bulb, you would first need to know your electricity rate per kilowatt-hour (kWh). Once you have that, you can convert the wattage of the light bulb to kilowatts (0.150 kW) and multiply it by the electricity rate to determine the cost per hour. Keep in mind that rates vary depending on your location and energy provider.
You have to pay for the work (enegy) of 150 watt hours. Scroll down to related links and look at "watt-hour - Wikipedia".
Per hour the answer is 400 watt-hours or 0.4 kW-hours (or units).
A watt is a measurement of electricity, usually pertaining to light. Light bulbs luminosity is graded by wattage, such as a 60 watt bulb, 100 watt bulb and so on. You would find a watt in a light bulb, to start.
A 60W bulb will use 60W X 1 hour / 1000. this will give you the KWh - the units your electricity company uses to charge you.So 60 X 1 =6060/1000 =0.060 Kwh
To calculate the cost of running a 15 watt bulb non-stop for a year, you first need to determine the cost of electricity per kilowatt-hour (kWh) in your area. Once you have that information, you can use the formula (Wattage/1000) x Hours Used x Days in a Year x Cost per kWh to find the annual cost. If the cost of electricity is $0.12 per kWh, running a 15 watt bulb non-stop for a year would cost approximately $15.79.
