A kilowatt-hour, expressed as kWh or kW·h, is a measure of energy that is equivalent to 1,000 watts of power for a 1-hour time period. Thus, to convert watts to kilowatt-hours, multiply the power in watts by the number of hours, then divide by 1,000. For example: let’s find the kWh of 1,500 watts for 2.5 hours.
Moreover, What is wattage formula?
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. For example, a 60-watt light bulb uses 60 joules per second.
Is 50 kWh a day a lot?
But since most homes are comparable enough in size and we can’t control the weather, 50 kWh per day is a good number to use, though maybe a bit on the high end for some homes.
Also How do you calculate kWh per day? One kilowatt is equal to 1,000 watts, so to figure out the kWh per day that your refrigerator uses, you simply need to divide the watt-hours per day (7,200) by 1,000 for a total of 7.2 kWh per day.
How much is a kWh electricity?
Both gas and electricity consumption is measured in kWh. The unit rate you pay will vary depending upon the energy price plan you’re on, and even the region you live in, but the average cost of electricity per kWh is 14.37p, and the average gas cost per kWh is 3.80p.

The work efficiency formula is efficiency = output / input, and you can multiply the result by 100 to get work efficiency as a percentage.
How do you calculate work?
The formula for work is , work equals force times distance. In this case, there is only one force acting upon the object: the force due to gravity. Plug in our given information for the distance to solve for the work done by gravity. Remember, since the object will be moving downward, the distance should be negative.
How do you calculate energy?
In classical mechanics, kinetic energy (KE) is equal to half of an object’s mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.
