Electrical Formulator contains over 100 formulas that solve electrical design problems. The program includes conversion of Kilowatts to BTUs, horsepower, joules and lumens. It also converts from Lumens. EFormulator calculates Amps both from AC and DC currents. It calculates kilowatts, horsepower, efficiency, power factor, watts, amps, current, power, resistance, and voltage. It includes formulas to calculate total resistance, capacitance, voltage drops, and transformer calculations. Every result in EFormulator can be saved. You can also select from favorites and recent formulas AND E-mail results This is theninth version of E-Formulator. In the coming months there will be updates that will include additional formulas. If there is a formulas that you would like that is not included just E-mail us and we will try to include it in the next update. EFormulator is the perfect formula calculator for anyone needing to do electrical calculations.The forumulas include:BATTERIESStarting motor amperageNumber of cells required Operating timeBTU CONVERSIONSbtu to caloriesbtu to cubic foot-atmbtu to foot pounds btu to foot-lbfbtu to gram-cal btu to gram-cmsbtu to horsepower-hrbtu to inch-lbfbtu to joulesbtu to kilocaloriesbtu to liter-atmbtu to pounds-calbtu to watt-hrCOSTSCost of operating lights and appliancesCost of using appliancesHours of usage of new bulbInsulation years to paybackKILOWATTS AND JOULES CONVERSIONSkilowatts to Btu/Hrkilowatts to btu/minkilowatts to btu/sec kilowatts to erg/seckilowatts to foot-lbs/hrkilowatts to foot lbs/minkilowatts to foot-lbs/seckilowatts to gigawattskilowatts to gram-cm/seckilowatts to (metric) horsepowerkilowatts to horsepwerkilowatts to joules/seckilowatts to kilogram-cal/minkilowatts to kilogram- cal/seckilowatts to kilogram-M/seckilowatts t lumenskilowatts to megajoules/hrlumenslumens to Btu min Lumans to btu secGENERATORDirect Current GeneratorGenerator amperage outputGenerator efficiency ImpedanceWhen resistance and reactance are known When resistance inductive reactance are known.MISCKva to KwParallel Circuits Total resistance Capacitance Reactance (X)Inductive Reactance Capacitance Reactance Bandwidth MOTORSLocked rotor currentSingle-phase motors Three phase motorsMotor KVA calculations When Fla is known When motor KVA per horsepower is known Motor KVA when above not known Speed of motorOHM'S LAWCalculate for powerPower Calculate for Resistance Calculate for voltage TRANSFORMERS Primary amperesSecondary amperes Transformers sizes full load curSingle phase 208 VSingle phase 240 v Single phase 480 v Three phase 208 v Three phase 240 v Three phase 480 v Rated full load Impedance of secondary Amperage capacity from secondaryVOLTAGE DROPVoltage drop calculations feet1 phase copper 1 phase aluminum 3-phase copper 3 phase Aluminum Voltage drop calculations meters1 phase copper meters 1 phase aluminum meter 3 phase copper meters 3 phase aluminum meters WIRINGWire size Wire length copper Wire resistance Wire length aluminum Amp to be calculated Conduit sizeThere are also almost 100 formulas in the conversion sections
