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

You have to pay for the work (enegy) of 150 watt hours. Scroll down to related links and look at "watt-hour - Wikipedia".
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 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.
What does 40 watts bulb mean?
An electrical watt is a measure of power. A 40 watt light bulb uses 40 watts of electrical power. It has a relative measure of twice the light output of a 20 watt bulb and one half the output of an 80 watt bulb. A 40 watt bulb uses 40 Joules of energy each second, or 40 watt-hours of energy each hour. In 1000 hours it uses 40 kilowatt-hours or Units of electrical energy.
How many watts per hour does 75 watt bulb use?
The bulb's power, 75 watts, is the power it uses continuously all the time it is switched on. The energy it uses can be measured in watt-seconds (Joules) or in watt-hours. A 75 watt bulb uses 75 watt-hours each hour, which is 0.075 kilowatt-hour.
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 much a hour does 100 watt bulb use at 15p?
A 100 w light bulb uses one tenth of a kilowatt of power, therefore in 1 hour it uses one tenth of a kilowatt-hour of energy, that is 0.1 units, or 1.5 p.
In a 60 watt light bulb how much energy is converted into heat?
What are the uses of Heat energy
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 much energy does a 95 watt light bulb use in 40 seconds?
The energy is 95 x 40 watt-seconds (Joules).
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.
How much energy does a 5 watt light bulb use off?
A lot
