When using in calculations of such physical quantity as power, often is required to transfer watts to other units of measure. The task is complicated by the fact that in the equipment outdated units of measure of power, such as "horsepower" are still used. But having all necessary tables and formulas, to transfer watts absolutely easily.

Instruction
1. That to translate watts in the corresponding units of measure, use the following table. One Watt corresponds: Milliwatts - 1000 Watts - 1 Kilowatts - 0.001 Megawatts - 0.000001 Joules a second - 1 Horsepower - 0.00134 Metric horsepower - 0.00136 Electric horsepower - 0.00134 Boiler horsepower - 0,000102fut-pound a minute - 44.25fut-pound a second - 0.74 dBm - 30 Calories per hour - 859.85 Kilocalories per hour - 0.86 British thermal units a second - 0.000948 British thermal units an hour - 3.41 Ton of cooling - 0.000284
2. To transfer the power specified in watts to other unit of measure, just increase the set number by the corresponding coefficient. For example, if the engine capacity of the car is 100000 watts, then in "horsepowers" it will be: 134 hp.
3. If watts in conditions asked to translate you the electric device is used. If the device is connected to the household electrical outlet, screwed in in an electrocartridge, or some is otherwise connected to the ordinary power supply network, then, most likely, voltage of 220 Volts of alternating current is used. Considering that tension, the current and power are interconnected by P=UI formula, gder – the power, U – tension, I – current, we receive a simple formula: I=P/220. That is, to calculate what current (in amperes) your power supply network at connection of the new device has to maintain, divide its power (in watts) into 220.
4. It is similarly possible to transfer watts to amperes for any electric device if tension of its food is known. It is even simpler to transfer watts, having used numerous programs converters or online services, for example, http://www.convertworld.com/ru/moshhnost/Ватт.html
