PowerECal - Power Electronics Power Supply and Magnetic Engineering Calculator includes the magnetic formulas calculation units conversion and wires conversion tables. It's a very useful tool for power electronic engineers.

Magnetic Builder:
Magnetic Builder is a useful magnetic design software. It is a tool for user to create his/her own magnetic component (inductor and transformer) by selecting different ferrite core bobbin type and winding method. Engineering drawing will be automatically produced to reduce user work load.

Magnetic Properties:
Transformer / Inductor / Magnetic flux density Calculator
- which can calculate peak flux density(Bp) against peak current Ip or voltage Von and duty cycle Don;
Magnetic Unit Conversion
- The conversion of MMF magnetomotive force between Oe and A/m and flux density between T and G;

Air Flow:
Volume & Velocity Unit Conversion
- The conversion among ft³/s m³/s cubic feet per minute(cfm ft³/min) million gallon per day(mgd) and Liter/s;
- The conversion among mile per hour(mph mile/hr) km/hr m/s feet per second(ft/s) and feet per minute(ft/min);
Temperature Rise vs Air flow Calculator
- which can calculate Velocity and Volume needed for the air flow through a box. By inputting cross section dimension power dissipation(Pd)inside the box and temperature rise(dT) of the outlet air flow result can be shown according to the provided illustration.

Wire Gauge sizes table:
- According to wire numbers list the different wire diameters in SWG(mm) and AWG(mm).

PCB Copper Trace Thickness Unit Conversion：
- The conversion among Ounce(oz) mil and milimeter(mm);

Energy Pressure and Power Unit Conversion:
- The conversion among Joule(J) calorie(cal) and British therm unit(Btu);

- The conversion between bar and N/m²;
- The conversion among horse power(hp) ft lb/s British therm unit per second(Btu/s) British therm unit per hour(Btu/hr) kW and Watt(W);

Temperature Unit Conversion:
- The conversion among degree Celsius(C) degree Fahrenheit(F) and Kelvin(K);

Dimension & Weight Unit Conversion:
- The conversion among cm³ inch³ Liter m³ and gallon;
- The conversion among Pound(lb) kg Newton(N) ton Ounce(oz) and g.
