Electrical Conversion Formulas for three-phase AC power:

*E* represents volts *I* represents amps *Eff* represents motor efficiency *PF* represents power factor - If
*PF* is not known, assume 0.85 - If
*Eff* is not known, assume 0.90

·To find **Amps** when **Horsepower** is known:

Amps = (hp × 746) ÷ (1.73 × E × Eff × PF)

·To find **Amps **when **Kilowatts **are known:

Amps = (kW × 1000) ÷ (1.73 × E × PF)

·To find **Amps **when **Kilovolt Amperes **are known:

Amps = (kVA × 1000) ÷ (1.73 × E)

·To find **Kilowatts **when **Amps**,** Volts **and **Power Factor **are known:

kW = (I × E × 1.73 × PF) ÷ 1000

·To find **Kilovolt Amperes **when **Amps** and **Volts **are known:

kVA = (I × E × 1.73) ÷ 1000

·To find **Kilowatts** when **Kilovolt Amperes **and **Power Factor **are known:

kW = (kVA × PF)

·To find **Kilowatts** when **Horsepower **and **Eff **are known:

kW = hp × 0.746 ÷ Eff

*Electrical Conversion Formulas for single-phase AC power:*

*E* represents volts *I* represents amps *PF* represents power factor - If
*PF* is not known, assume 0.85 - If
*Eff* is not known, assume 0.90

·To find **Amps** when **Horsepower** is known:

Amps = (hp × 746) ÷ (E × Eff × PF)

·To find **Amps **when **Kilowatts **are known:

Amps = (kW × 1000) ÷ (E × PF)

·To find **Amps **when **Kilovolt Amperes **are known:

Amps = (kVA × 1000) ÷ (E)

·To find **Kilowatts **when **Amps**,** Volts **and **Power Factor **are known:

kW = (I × E × PF) ÷ 1000

·To find **Kilovolt Amperes **when **Amps** and **Volts **are known:

kVA = (I × E) ÷ 1000

·To find **Kilowatts** when **Kilovolt Amperes **and **Power Factor **are known:

kW = (kVA × PF)

·To find **Kilowatts** when **Horsepower **and **Eff **are known:

kW = hp × 0.746 ÷ Eff
