Kilowatt-hour is an energy unit (symbol kWh or kW⋅h).
One kilowatt-hour is defined as the energy consumed by power consumption of 1kW during 1 hour:
1 kWh = 1kW ⋅ 1h
One kilowatt-hour is equal to 3.6⋅106 joules:
1 kWh = 3.6⋅106 J
The energy E in kilowatt-hour (kWh) is equal to the power P in kilowatts (kW), times the time t in hours (h).
E(kWh) = P(kW) ⋅ t(h)
For example what is the energy consumed when consuming 2kW for 3 hours?
Solution:
E(kWh) = 2kW ⋅ 3h = 6kWh
1kWh = 1000Wh = 0.001MWh
1kWh = 3412.14163312794 BTUIT = 3.41214163312794 kBTUIT
1kWh = 3.6⋅106J = 3600kJ = 3.6MJ = 0.0036GJ

kWh meter is the electric meter that measures the amount of electrical energy in kWh that was consumed in the house. The kWh meter has a counter display that counts units of kilowatt-hour (kWh). The energy consumption is calculated by calculating the difference of the counter's reading in the specified period.
The cost of your electricity bill is determined by how much electricity you use and the rate your utility charges. Your utility company measures how much electricity you use with a meter, which records how many kilowatt-hours (kWh) of electricity you use each month.
The cost of electricity per kWh varies depending on your utility company, your location, and the time of year. You can use this website to calculate the cost of your electricity bill.
This is a difficult question to answer without knowing more about the specific house. A kilowatt-hour is a unit of energy, and it takes different amounts of energy to power different things. For example, it takes more energy to power a large air conditioner than it does to power a small fan.
Generally speaking, a house will use between 800 and 1,000 kilowatt-hours of energy per month. This number can vary depending on the size of the house, the climate, and the type of appliances and electronics that are used.
