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 =
60
60/1000 =
0.060 Kwh

Watt hour efficiency?
The Watt hour efficiency is the ratio of the amount of energy available during the discharge of an accumulator to the amount of energy put in during charge.
How many watts per hour to equal 1000 btu's?
The energy unit is not watts per hour, but watts times hour, simply called watt-hours.One BTU is equal to about 1055 Joules or Watt-seconds; that is about 0.293 watt-hours. Actually there are different definitions of the BTU.The energy unit is not watts per hour, but watts times hour, simply called watt-hours.One BTU is equal to about 1055 Joules or Watt-seconds; that is about 0.293 watt-hours.

How does watt and joule relate?
The Joule is a unit of energy, while the Watt is a unit of power. Joule is the alternate name for a Newton-meter of energy, and Watt is the alternate name for a Newton-meter per second of power. This means that one Watt is one Joule per second; a 100-Watt light bulb converts 100 Joules of electrical energy every second into heat energy and light energy.
How many kilowatt hour make 1 watt?
1kilowatt = 1000 watts but you cannot compare a kilowatt hour to a watt, the extra dimension of time changes what is being measured. The watt is a measure of power. The watt second and the kilowatt hour is energy. The misunderstanding comes from our use of the term POWER COMPANY for our electricity suppliers. They bill us in kilowatt hours which is energy, not power.
How much does it cost to run a 100 watt bulb per hour?
That bulb is 100 watts or 0.1 kilowatts so it uses 0.1 kilowatt-hour of energy each hour, which costs about £0.015
How much a hour does 100 watt bulb use at 15p?
A 100 watt bulb uses 0.1 kilowatt (100 watts / 1000) per hour. At 15p per kilowatt-hour, the cost of running the 100 watt bulb for an hour would be 1.5p (0.1 kW * 15p).
How much electicity is used in a 48 watt bulb in an hour?
It uses 48 watt-hours each hour. In 20 hours and 50 minutes it uses 1 kilowatt-hour or 1 unit of electrical energy, which costs about £0.15
How much does a 60 watt light bulb use per hour?
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 16.66 60watt bulbs on for one hour would cost 10 cents.
How long does it take for a 100 watt light bulb to cobsume 100 units of energy?
Assuming the 100 watt light bulb is always on, it would consume 100 units of energy in 1 hour (100 watt-hours = 0.1 kilowatt-hour = 1 unit of energy per hour).
How much electricity does a 60 watt bulb use per hour?
"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.
What does 40 watts bulb mean?
A 40-watt bulb refers to the power consumption or energy usage of the bulb. It indicates the amount of electricity the bulb consumes when it is turned on. In general, the higher the wattage, the brighter the light emitted by the bulb.
How much energy does it take to light a 60-watt light bulb for an hour?
Actually, your wrong. Sure, the lighting ithat is set for proper illumination is 60watts, but if anyone is used to using a dimmer, you can dial down the power consumption for a typical incandescent bulb and it will still light. And as expected, the light level will decrease as you lower the dimmer setting as well.
How much work is done using a Watt light bulb for 1 hour?
The energy used (work done, same thing) is 120 watt-hours, which is also 0.12 units or 120x3600 joules.
How long does it take a 60 -watt light bulb to consume 60 -watt hours of energy?
60 watt-hrs= 60 watt*1 hr so it will take 1 hour.
How many kWh will a 32 watt fluorescent bulb use?
A 32-watt fluorescent bulb, when used for 1 hour, will consume 0.032 kWh (32 watts ÷ 1000). The energy consumption can be calculated by multiplying the wattage by the number of hours used.
How much energy does a nightlight use compared to a 100 watt bulb?
An incandescent nightlight bulb is either 4 watt or 7 watt. A 4 watt bulb uses 1/25th (0.04) the power of a 100 watt bulb. A 7 watt bulb uses 7/100th (0.07) the power of a 100 watt bulb. There are LED and other types of nightlights that use much less power than this. To find the energy total used multiply the power (in watts) by the total time the light is on (in hours) to get energy (in Wh). If you want kWh divide this by 1000 as a watt is 1/1000th of a kW.
