how do you calculate electricity units?

for instance, If you switched ON a 1000 watt bulb for 1 hour, It mean you consumed 1000 watts for an hour i.e. (1000 watts for 1 hour = 1kWh = 1 unit of Energy). So if the rate of unit is $5 , then you will pay 5 Dollars as a bill for your bulb which consumed 1kWh = 1 unit of electricity.

To determine the wattage, use a simple multiplication formula. The ampere (or amps) is the amount of electricity used. Voltage measures the force or pressure of the electricity. The number of watts is equal to amps multiplied by volts.

The formula for calculating wattage is: W (joules per second) = V (joules per coulomb) x A (coulombs per second) where W is watts, V is volts, and A is amperes of current. In practical terms, wattage is the power produced or used per second.

Calculate Watt-hours Per Day One kilowatt is equal to 1000 watts, so to calculate how many kWh a device uses, divide the watt-hours from the previous step by 1000.

['Calculate the daily energy consumption: (Wattage) x (hours used per day) Divide the answer by 1,000.', 'Calculate the annual use: (Daily energy consumption) x (number of days the appliance is used per year)', 'Multiply #2 by your energy cost.']

Find the energy used in kilowatt hours (kWh) by multiplying the total wattage for the fixture by the hours per day that the lights are on. Next, divide this by 1,000. To determine the monthly cost, multiply the energy used per day by 30 to get the monthly kilowatt hours used.

['P(kW) = √3 × PF × I(A) × VL-L(V) / 1000.', 'kilowatt = √3 × PF × amp × volt / 1000.', 'kW = √3 × PF × A × V / 1000.', 'P = √3 × 0.8 × 3A × 110V / 1000 = 0.457kW.']

1 kWh (kilo watt hour) and 1 Unit are same. 1 kWh is the amount of energy consumption by 1 kW load in one hour. Therefore, 1 Unit = 1 kWh. Therefore, 1 Unit Electricity is equal to 3.6×106 Joule of electrical energy consumption.

Joules = watts x seconds This is the most basic formula for a joule. Basically, you can work out how many joules are being exerted by multiplying power by time. A watt is a unit of power.

["Current meter reading – Meter reading reported from last month's bill = Total kWh used since last reading.", 'Total kWh used since last reading x Charge per kWh = Total energy charge.']

How do I calculate the maximum power that my electrical installation can supply? To calculate the maximum power that your meter can supply (expressed in volt-amperes), multiply the voltage (U) by the intensity (I) of the current that supplies your home.

['kWh = P(W) × T(h/day) ÷ 1,000(W) kWh = 400 W × 4 hrs ÷ 1,000. kWh = 1.6 kWh.', 'Price = Electricity(kWh) × Cost(cost/kWh) Price = 1.6 kWh × $.12. Price = $.19 per day.', 'Monthly Price = $.19 per day × 30. Monthly Price = $5.70.']

Electric power is the rate at which a device changes electric current to another form of energy. The SI unit of power is the watt. Electric power can be calculated as current times voltage. Electrical energy use equals the power of the appliance multiplied by the amount of time the appliance is used.

A unit (as mentioned on the electricity bills) is represented in kWH or Kilowatt Hour. This is the actual electricity or energy used. If you use 1000 Watts or 1 Kilowatt of power for 1 hour then you consume 1 unit or 1 Kilowatt-Hour (kWh) of electricity.
