What is a Kilowatt Hour or kWh?The kilowatt hour is a unit of energy equal to 3.6 megajoules. If the energy is being transmitted or used at a constant rate (power) over a period of time, the total energy in kilowatt hours is equal to the power in kilowatts multiplied by the time in hours. The kilowatt hour is commonly used as a billing unit for energy delivered to consumers by electric utilities.
A kWh is a measure of how much energy you’re using.
It is simply a unit of measurement that equals the amount of energy you would use if you kept a 1,000 watt appliance running for an hour.
Energy consumptionThe 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:
E(kWh/day) = P(W) × t(h/day) / 1000(W/kW)
So if you switched on a 100 watt light bulb, it would take 10 hours to rack up 1 kWh of energy.
Or a 2,000 watt appliance would use 1 kWh in just half an hour.
While a 50 watt item could stay on for 20 hours before it used 1 kWh.
If you have a RIG or ASIC at 900W your consumption will be:
900W * 24h = 21.600Wh or 21.6kWh/day (1 kWh = 1000Wh)
21.6kWh * 30 = 648 kWh/month
You can calculate the final price by multipling the consumption of 648 kWh by the price of your kWh, usually you can find this information on your billing.
We will take the price of $0.10 for the exemple so final price will be:
648kwh * $0.10 = $64.85
Some country and territory may have extra fee and taxes for high consumption that increase the final cost.
For accurate consumption you need a tool like kill-a-watt to measure it in real time.
