FORMULAS FOR
CALCULATING AMPERES
the formulas below are at 100% power factor
Single Phase
 |
horsepower times 746,
divided by the voltage,
will give you amperage |
 |
wattage divided by
voltage will give you
amperage |
 |
kilowatt times 1000,
divided by the voltage,
will give you amperage |
 |
kilovolt amperes times 1000,
divided by the voltage,
will give you amperage |
 |
voltage times amperage
will give you wattage |
 |
voltage times amperage
divided by 746
will give you HP |
Three Phase
 |
horsepower times 746,
divided by
the voltage times 1.73,
will give you amperage |
 |
wattage divided by
the voltage times 1.73
will give you amperage |
 |
kilowatt times 1000
divided by
the
voltage times 1.73,
will give you amperage |
 |
kilovolt amperes times 1000
divided by
the
voltage times 1.73,
will give you amperage |
 |
voltage times amperage
times 1.73
will give you wattage |
 |
voltage times amperage
times 1.73
divided by 746
will give you HP |
