Advice 1: How to convert watt to kilowatt

The word power is associated with words engine, car, battery, battery, etc. And no wonder, because power is a physical quantity that shows how fast you are working. Power is measured in Watts, in honor of the English scientist James watt. Watt is denoted as 1W. Theoretically, one watt is one Joule divided by one second (1W=1/1s). In practice it is often found the expression of kilowatts, it is also power, but with a different unit of measurement.

For the translation of watt to kilowatt (hereafter, kW), you must know that are multiples of the decimal prefix "kilo" means "thousand" means one kilowatt equals one thousand watts (1kW = 1000W). To convert kilowattsin watts, multiply this value by one thousand. By multiplying the number by a thousand, the comma is transferred to three digits to the right of the original location among. Example 1. 4 kW = 4000 W, 0.4 kW = 400 watts, 3.5 kW = 3500 W, 89 kW = 89000 watts.

Sometimes you have to translate from watts to kilowatts. This action back above in the first step of translation. That is, one watt is equal to one thousandth of a kilowatt (1 watt = 0,001 kW). Then, when translating, it is necessary to multiply the number of one-thousandth or divided into one thousand, to move the comma in the three digits to the left from the initial position in the number. Example 2. 1000 watts = 1 kW 37 W = 0,037 kW, 5 W = 0,005 kW, 86000 W = 86 kW.

Advice 2: How to convert watts

When used in the calculation of such physical quantities as power, is often required to transfer watts to other units. The task is complicated by the fact that the technique still used obsolete units of measurement of power, such as "horsepower". But with all of the necessary tables and formulae, translate watts quite easily.

To put watts in the appropriate units, use the following table.One Watt corresponds to:Milliewatts - 1000
Watt - 1
Kilowatts - 0,001
Megawatt - 0,000001
Joules per second - 1
Horsepower 0,00134
Metric horsepower 0,00136
Electric horsepower 0,00134
Boiler horsepower 0,000102
Foot-pound per minute - a 44.25
Foot-pound per second - 0,74
dBm - 30
Calories per hour - 859,85
Kilocalories per hour is 0.86
British thermal unit per second - 0,000948
British thermal unit per hour is 3.41
A ton of refrigeration is 0,000284

To translate the power, specified in watts, a different unit of measure, simply multiply the given number by that factor. For example, if the engine power output is 100,000 watts, the "horsepower" it would be: 134 HP

If You were asked to convert watts to amps, you should not accuse his interlocutor of incompetence and inadequacy. Specify the conditions in which you use the appliance. If the device is connected to a household electrical outlet is screwed into electroputere, or in some other way connected to a conventional power supply, then most likely, you use a voltage of 220 Volts AC. Given that the voltage, current and power are interrelated by the formula P=UI, where
P – power
U – voltage,
I – current,get a simple formula: I=P/220.
That is, in order to calculate the current (in amperes) must be able to withstand your mains when you connect a new device, share in his power (in watts) at 220.

Similarly, you can transfer watts to amps for any appliance, if you know the voltage supply.
Even easier to translate watts, using numerous programs-converters or online services, such as http://www.convertworld.com/ru/moshhnost/Ватт.html
Note
A comma in a number is not put, it is behind the last digit in the number.
Useful advice
This action is subject to the transfer of power both mechanical and electric, even if they are calculated by different formulas.
