  • 1 Horsepower = 1 Kilowatt (Approx.)
  • Amps x Volts = Watts

CALCULATOR

1. Total Amps @ 120 Volts (Appliances)  Amps.
2. Total Amps @ 240 Volts (Appliances)  Amps.
3. Multiply LINE 1 X 120  Watts.
4. Multiply LINE 2 X 240  Watts.
5. Add LINE 3 and 4  Watts.
6. Divide LINE 5 by 1000 (1000 Watts = 1KW)  KW.
7. Total HP in motors
Note, each motor must be separately entered, do not combine or sum up multiple motors into one line


Line 7 Total  HP.
8. Horse power from Largest Motor  HP.
9. Add Line 7 total and Line 8 (1HP = 1KW)  KW.
