Converting kilowatts to amps first requires knowledge of the current type, whether it is DC, AC single phase or AC three phase, as each calculation differs. Additionally, the voltage in volts must also be known for all three calculations.
For DC kilowatt to amp conversions, multiply 1,000 by the power in kilowatts and then divide by the volts to arrive at the amps. For single phase AC kilowatts, multiply the power in kilowatts times 1,000 then divide that number by the volts multiplied by the power factor. Finally, for three phase AC kilowatts with line to line voltage, multiply 1,000 times the kilowatts, and then divide that number by the square root of 3 multiplied by the power factor times the line-to-line RMS voltage.

Full Answer >One liter is the equivalent of approximately 0.2642 gallons. As both terms are measurements of volume, one can convert between the two by utilizing the fact that there are about 3.785 liters per gallon.
Full Answer >A three-phase induction motor's RPM can be calculated using a relatively simple mathematical formula. RPM is equal to (120 x frequency)/number of poles in the motor.
Full Answer >A bag of cement weighs 94 pounds. Concrete mix typically uses five bags of cement, or 470 pounds, per yard of concrete to be poured. Concrete mix includes rocks and sand along with cement.
