To transfer the electrical power (occasionally say heat capacity) to any other unit of measurement, use of data on the ratio of different units. To do this, simply multiply the given number of power ratio that matches the unit of measure in which to translate.
1 Watt-hour is equivalent to only 3.57 kJ;
1 Watt is equal to 107 erg/s; 1 j/s; 859,85 cal/h; 0,00134 HP
For example, the organization pointed out a number 244,23 kW, which should translate into calories.
244,23 kW => 244,23* 1000 watts = 244,23* 1000* 859,85 => = 210 000 000 cal/h or 0.21 G cal/h

In the calculations related to power, typically use the standard consoles, especially when the measured value is too small or, on the contrary, large. This simplifies the calculations associated with the order value. Watts by itself is almost never used. Put the multiple number among a form according to the scheme given below.
1 micro (MC) => 1*0,000001
1 mile (m) = > 1*0,001
1 Santi (C) => 1*0,01
1 deci (d) => 1*0,1
1 Deka (da) => 1*10
1гекто (g) => 1*100
1 kilo (K) => 1*1 000
1 Mega (M)=> 1*1 000 000
1 Giga (G) => 1* 1 000 000 000
1 micro (MC) => 1*0,000001
1 mile (m) = > 1*0,001
1 Santi (C) => 1*0,01
1 deci (d) => 1*0,1
1 Deka (da) => 1*10
1гекто (g) => 1*100
1 kilo (K) => 1*1 000
1 Mega (M)=> 1*1 000 000
1 Giga (G) => 1* 1 000 000 000

Find out what kind of unit of measure of heat energy required to transfer power. The options are: j or Joule – unit of work and energy; Cal (Calories) is the unit of heat energy, can be written simply as calories, and might look like this – kcal/hour.
Note
Sometimes you have to work with very large numbers, so you can get lost in the conversion of a number to the integer part. Translate power into energy slowly and use a scientific calculator.
Useful advice
Don't confuse kW and kWh. These two units are often confused, especially when speaking about appliances. But these two units belong to different physical quantities. In watts and kilowatts measure power, i.e. the amount of energy that the device consumes per unit time. WH or kWh, they are determined by the amount of work performed by this device.
