E kWh P kWT h 2 T 15 minutes Convert the minutes into hours. KWh to watts calculator Watts to kWh calculation The energy E in kilowatt-hours kWh is equal to the power. 1 BTU 00002931 kWh 1 kWh 3412 BTU BTUh BTU per hour is a unit of power that represents the energy transfer rate of BTU per hour.
A kilowatt-hour is referred to as a measure of electrical energy that is equal to one kilowatt or 1000 watts of power over a 1 hour period. For example lets calculate the power consumed by a 10 watt. Formula of converting watts to Kilowatt hours E kWh P W x t hr 1000 which means that the energy.
How to convert BTU IT to kilowatt-hour. The relevant fields will automatically update as you move through the tool to calculate your kilowatt hours kwh and use this against your existing electricity price per kwh resulting in an. Electrical energy is measured in kilowatt-hourskwh or kw-h 1 kWh one kilowatt of energy consumed for 1 hour of time Formula of Ah to Kwh conversion KWh Ah x v 1000.
Divide the watt hours by 1000 to calculate the kilowatt hour. The energy E in kilowatt-hours kWh per day is equal to the power P in watts W times number of usage hours per day t divided by 1000 watts per kilowatt. Kilowatt hours milliamp hours volts 1000000 Abbreviated.
For example If the power in kilowatts is. Ah kWh V 1000. E kWh P kW x t hr which means that the energy in Kilowatt-hours is calculated by multiplying the power in Kilowatts by the time in hours.
A kWh calculator can help do these calculations for you and also factor in total usage amounts. Divide the 15 minutes by 60. Kilowatt-hour Calculator Electricity usage calculator Each home and apartment has its own unique usage profile so the best way to shop for electricity is with your exact usage.
