in electronics, there is a term of Watt Hours used in power bills and things. watts itself is a unit derived by 1 joule per second. in order to get watt hours (which is just 1 joule per hour) you multiply your watts (joule/second) by 360 (60 seconds in a minute multiplied by 60 minutes in an hour). that will then give you units of joules/hour

How many watts are in a one hundred watt lamp?
None, the watts come form the electricity supply and the lamp uses them at a rate of 100 an hour when it is turned on.
How many watts does a microwave consume in an hour?
Watts are units for measuring the rate of energy consumption. So it is meaningless to speak of how many watts something consumes in a length of time. (It would be like asking how many miles per hour a car drives in an hour.)Energy consumption may be measured in kilowatt-hours. A typical microwave consumes 1500 watts, which would be 1.5 kilowatt-hours in one hour.
How much is a Meter cubed per hour in W?
Meter3/hour would be a flow rate, or rate of change of volume with time.I can't think of anything abbreviated 'W' that would correspond to that unit.Certainly not 'Watts'.
How many kliowatt hours does a 120 watt fixture use in 1 hour?
One kilowatt hour (kWH) is the amount of power used at the rate of 1000 watts for one hour. Therefore a device of 120 watts running for one hour would consume 120 / 1000 x 1 = 0.12 kWH
A college student produces about 100 kilocalories of heat per hour on the average what is the rate of energy production in watts?
116 W
A kilowatt-hour is equal to how many watts of electricity used for one hour?
1,000 watts
How many kilowatt hours - KWh - are used to light a 30 watt light bulb for 1 hour?
A kilowatt is 1,000 Watts. 30 Watts is equal to 0.03 kilowatts. A kWh or kilowatt-hour is the rate of electrical usage. It is a measure of kilowatts used per period of time (1 hour). 1 kWh is 1 kilowatt (1,000 watts) for 1 hour. So, multiply your 30 watts (0.03 kilowatts) by 1 hour to get kWh. =0.03 kWh In about 33 hours and 20 minutes, this lamp would use 1 kWh.
How long is a watt hour?
A watt hour is a unit of energy, not time -so you cannot ask how 'long' it is. The time taken to consume a watt hour of energy depends upon the rate (i.e. the power) at which it is consumed, expressed in watts. A watt hour is defined as the amount of energy consumed, over a period of one hour, at the rate of one watt.
What does a kilowatt-hour measure?
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.
How many watts are used in a solar cell per hour?
100 watts
How many watts does a fan use per hour?
3/4 of watts
How many kilo watts does a 5.5 watts water filter consume in one hour?
5.5 watts is 0.0055 kilowatts. in one hour the equipment uses 0.0055 kilowatt-hours.
