Design a mains transformer from the core you have. Choose EI, C-core or toroid; set Bmax or k-factor; add every secondary you need. Get VA rating, turns per volt, turns and wire gauge for every winding, and a window-fill warning when the wire won't fit.

How to use
Two sizing modes — by Bmax (T) or by k factor.
What it's for
Design a mains transformer from the core you have: VA rating, turns/volt and every winding with its wire.
You enter
Core dimensions — EI, C-core, toroid or manual (the app draws the core with dimensions labelled).
Current density, primary voltage, each secondary (voltage + current), and a regulation allowance.
You get
The VA the core supports, turns per volt, turns and wire gauge for every winding, primary current.
Window fill — with a warning when the wire will not physically fit.
