Electrical power is the rate at which a device converts electrical energy, measured in watts. For a DC or purely resistive load it is simply voltage times current, P = V × I. For an AC load with a power factor below 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.
As a worked example, a device on a 120 V circuit drawing 10 A at unity power factor uses P = 120 × 10 = 1,200 W, which is 1.2 kW or about 1.61 hp. If instead it were a motor with a 0.8 power factor, the real power would fall to 120 × 10 × 0.8 = 960 W even though it still draws the same 10 A. Divide watts by 745.7 to convert to horsepower, or by 1,000 to get kilowatts.
The advanced usage fields turn power into running cost. Daily energy in kilowatt-hours is the power in kW multiplied by the hours used per day; multiply by your price per kWh for the daily cost and by 30 for a monthly estimate. A 1.2 kW load run 4 hours a day uses 4.8 kWh daily, about 144 kWh a month, which at $0.15/kWh is roughly $21.60 a month — the kind of figure that helps compare appliances, size a generator or budget a workshop.
Zvimwe zvinobvunzwa zvakanyanya
Chii chinonzi formula yemagetsi?
Real simba muwatts ndi P = V × I × PF. For DC kana a resistive kutakura simba factor ndi 1, saka simba ndi nyore voltage nguva iri.
Maawa mangani muzvitima?
Mumwe mechanical horsepower imwechete 745.7 watts, saka 1492 W kutakura ndiro pamusoro 2 hp. Divide watts ne 745.7 kuti ashandure.
Sei mutengo wekushandisa wakashanda?
Daily energy is power (kW) × hours per day, in kWh. Multiply by 30 days and your price per kWh to estimate the monthly cost.
Chii chinonzi power factor uye ndiani anofanira kuichinja?
Power factor inonziwo fraction of apparent power (V × I) iyo inoita basa rakanaka. Inogona kunge iri 1 kana iri DC uye resistive loads sezviri kuitwa nemagetsi emagetsi, asi inogona kunge iri 0.7-0.9 kana iri mota kana zvimwe zvinhu zvemagetsi.
Chii chinonzi chiyero chekuenzanisa pakati pewatts nevolt-amperes?
Watts ndezvechokwadi simba (V × I × PF); volt-amperes ndezvechokwadi simba (V × I) pasina simba-factor kugadziriswa. Yeresistive kutakura ivo vakaenzana, asi yereactive kutakura VA rating iri pamusoro, izvo ndizvo nei generator uye UPS ratings zvinopihwa muVA.
Maitiro ekushandura watts kuita horsepower?
Divide the watts by 745.7. So 1,200 W is about 1.61 hp, and a 1 hp motor draws roughly 746 W of mechanical-equivalent power (more electrically, once efficiency losses are included).
