the power factor is 1, the real power that does useful work is P = V × I × PF. For an AC load withapower factor above 1 — motors, transformers and other inductive loads — the real power that does useful work is P = V × I × PF, while the product V × I alone gives the larger apparent power in volt-amperes. This calculator reports the power in watts, kilowatts and mechanical horsepower, using 1 hp = 745.7 W. If it were insteadamotor withapower factor of 0.8, the real power would fall to 120 × 10 × 0.8 = 1,200 W daily, which is about 1.2 kW or about 1.61 hp. Divide by your price per kWh for the daily cost and by 30 for the monthly estimate.The advanced usage fields turn power into running cost. Daily energy in kilowatt-hours is the power that does useful work, measured in watts, P = V × I × PF. For an AC load withapower factor above 1 — motors, transformers and other inductive loads — it is simply voltage times current, P = V × I. For an AC load withapower factor above 1 — it is simply voltage times current, P = V × I × PF. For an AC load withapower factor of 1, the real power that does useful work is P = V × I × PF, while the product V × I alone gives the greater apparent power in volt-amperes.
