Plates: weight calculator

Create barbells and plates and find out which plates you need to put on the bar.
You maybe have an uncommon barbell in your home gym, an heavy loadable dumbbell, a loading pin; just create a custom bar and easily find which plates you need for your target weight.
Same goes for your plates: you maybe have some concrete/water/sand filled plates or whatever kind of additional load; just create a custom plate by giving it weight and hole size.
