Electrical Formulator

iOS Universal

ELECTRICAL FORMULATOR contains over 100 formulas that help solve electrical design problems. The program includes conversion of Kilowatts to BTU’s, horsepower, joules and lumens. ELECTRICAL FORMULATOR also converts from lumens. ELECTRICAL FORMULATOR calculates amps both from AC and DC currents. It calculates kilowatts, horsepower, efficiency, power factor, watts, amps, current, power, resistance, and voltage. The program includes formulas to calculate total resistance, capacitance, voltage drops, and transformer calculations.

Every result in ELECTRICAL FORMULATOR can be saved. You can also select from favorites and recent formulas and e-mail results when you like.

ELECTRICAL FORMULATOR is the ninth version of EFormulator. In the coming months there will be free updates for current users that will include additional formulas. If there is a formulas that you would like that is not currently included, just e-mail us and we will try to include the formula in the next update.

ELECTRICAL FORMULATOR is the perfect formula calculator for anyone needing to do electrical calculations.
