How many joules of electric energy are there in 1 kilowatt-hour?
A kilowatt-hour (kWh) is a unit of measurement for electric energy. It is equal to the amount of energy consumed by using one kilowatt (kW) of power for one hour.
There are 3,600,000 joules in 1 kilowatt-hour. This conversion is based on the definition of a kilowatt-hour, which is equal to 3,600 seconds multiplied by 1 kilowatt (1000 watts).
The kilowatt-hour is commonly used as a unit of electric energy because it is a more practical and convenient unit for measuring the amount of energy used by electric appliances and devices. It also reflects the cost of energy on electricity bills.
The energy consumption of appliances is typically measured in kilowatt-hours (kWh) by multiplying the power rating of the appliance (in kilowatts) by the time it is used (in hours). This gives the total amount of energy used by the appliance.
No, the conversion factor between kilowatt-hours and joules is specific to electric energy. Different forms of energy, such as thermal or mechanical energy, have their own conversion factors to joules.
