The electrical formula for calculating the Horsepower , Watts .Ampere and KVA are given below .
|Need to find||Electrical Formula|
|Horsepower DC||(Volts x Ampere x Efficiency)/746|
|Horsepower AC||(Volts x Amperex1.732xefficiency x power factor )/746|
|Watts DC||Volts x Amperes|
|Watts AC||Volts x amperes x Power factor x 1.732|
|Kilowatts||(Volts x amperes x Power factor x 1.732)/1000|
|Ampere AC||(746 x Horsepower )/(Volts x efficiency x power factor x 1.732 )|
|KVA||(volts x ampere x 1.732)/1000|
|Fan Motor HP||( CFM x pressure (lbs/sq ft) )/ (3300 x efficiency )|
|Pump Motor HP||( GPM x Head (ft) x specific gravity )/(3960 x efficiency of pump )|
