To find out how much energy is transferred in an hour in joules, you need to know the power consumption of the device in watts. You can calculate the energy transferred by multiplying the power in watts by the time in hours. The formula is Energy (joules) = Power (watts) x Time (seconds).

How many joules of energy are in 1 kWH?
There are 3.6 million joules of energy in 1 kilowatt-hour (kWh).
How many joules are in different units of energy?
1 calorie = 4.184 joules 1 kilowatt-hour (kWh) = 3.6 million joules 1 British thermal unit (BTU) = 1,055 joules
What is a measure of eletrical energy equivalent to one kilowatt hour?
A measure of electrical energy equivalent to one kilowatt hour is a unit of energy equal to 3.6 million joules.
What is difference between Kilowatt power vs kilowatt hour?
Kilowatt (kW) is a measure of power, representing the rate at which energy is consumed or produced. Kilowatt-hour (kWh) is a measure of energy, representing the total amount of energy consumed or produced over time. For example, running a 1 kW appliance for 1 hour consumes 1 kWh of energy.
Give three ways of measuring energy?
Joules: The International System of Units measures energy in joules, representing the energy transferred to an object when a force of one newton acts on it over a distance of one meter. Kilowatt-hours: Commonly used to measure electrical energy consumption, a kilowatt-hour is the amount of energy used by a 1,000-watt appliance in one hour. British Thermal Units (BTU): Another unit of energy commonly used in the United States to measure heat energy, with one BTU being approximately equal to the energy required to heat one pound of water by one degree Fahrenheit.
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 joules of energy are in 1 kWH?
There are 3.6 million joules of energy in 1 kilowatt-hour (kWh).
How many joules are in different units of energy?
1 calorie = 4.184 joules 1 kilowatt-hour (kWh) = 3.6 million joules 1 British thermal unit (BTU) = 1,055 joules
What is a measure of eletrical energy equivalent to one kilowatt hour?
A measure of electrical energy equivalent to one kilowatt hour is a unit of energy equal to 3.6 million joules.
What measurement is energy measured in?
It depends, If you measure your own energy it would be in joules, if it is for your house you measure it with kilo-watt hour
What is the equation of converting horsepower to joule?
Horsepower is a unit of power, but joules is a unit of energy. To convert horsepower to joules, you need an additional time parameter. One horsepower is about 745.7 watts. So a horsepower-hour is 745.7 watt-hours. One watt-hour is 3600 joules. A horsepower-hour is then 745.7 times 3600 = 2684520 joules.
Write a relation between commercial unit of electricity and the SI unit of energy?
The commercial unit of electricity is typically measured in kilowatt-hours (kWh), while the SI unit of energy is measured in joules (J). One kilowatt-hour is equal to 3.6 million joules.
What is difference between Kilowatt power vs kilowatt hour?
Kilowatt (kW) is a measure of power, representing the rate at which energy is consumed or produced. Kilowatt-hour (kWh) is a measure of energy, representing the total amount of energy consumed or produced over time. For example, running a 1 kW appliance for 1 hour consumes 1 kWh of energy.
What unit measures electrical energy consumption?
In physics, the total amount of energy is measured in joules. The rate of energy use - joules/second - is the power, the unit is also known as watt. Electricity companies tend to use another measure for energy use: the kilowatt-hour (kWh), which of course is equal to 3.6 million joules.

What is cost of btu?
This depends on the cost per kilowatt hour in your area.
How many joules are equivalent to one kilowatt per hour?
The energy 1 kilowatt-hour (kWh) is 3600000 joules.AnswerThere is no such thing as a 'kilowatt per hour'. You probably mean 'kilowatt hour'?
