To translate kilowatt kilowatt-hours (kWh per kWh), verify that it is measured in kilowatts.

If "kilowatts" measured the meter, and in the time of payment you are required to specify the kilowatt-hours, just to correct kilowatt kWh. The name "kilowatts' (kW) is often used in everyday life for the abbreviated name of a kilowatt-hour.

Sometimes kW kWh to be translated to estimate how much electricity "wound" on the elec
tricity meter electrical works for some time.

To calculate how many kilowatt-hours of energy will be expended device, multiply its power (in kW) for the duration of time (in hours).If the power or the time specified in other units, before starting the calculations required to bring them to the above.

For example, if you want to know how much electricity will be used bulbs with 100 watts (W) for a half day, first turn watts kilowatts (100 W = 0.1 kW), and the day - to watch(0,5 days = 12 hours).Now multiply the obtained values ​​of power and time.It turns out: * 12 = 0.1 1.2 (kWh).

Using the method described above, it is possible to estimate the power consumption of the entire apartment during the month (for example, planning the family budget).Of course, you can just lay down all electrical power and multiply that amount by the number of hours per month (30 * 24 = 720).However, this way you get a much higher valuation of energy consumption.For a more accurate calculation should take into account the actual average time of each appliance for a month, then multiply this time, the power of this device, and then lay down their energy consumption figures for all devices.

For example, if one bulb 60W hanging in the entrance and reception, and the second, 100-watt lights WC and involved about 1 hour per day, for a month counter "to wind»:

0,06 * 24* 30 + 0.1 * 1 * 30 = 43.2 + 3 = 46.2 (kWh).
