You put something in here like "20" and "cm" for a cake tin, or "4" and "persons". This is for your own reassurance only, for whatever it is, ml, oz, cups, gr.: I don't care, as long I have a number to crunch on.
Remember, you can't put in a new type because I can't tell you e.g. how many grammes would be eaten by 20 persons!
Please mind that you may have to take a new cooking length into account. That is something I cannot do for you, alas...
This handy tool is part of my Playground - a collection of fun stuff I like to make, from jQuery games to CSS animation tests.
It consists of Bootstrap, jQuery and LESS/CSS3.
Please drop in on the playground section of my portfolio site www.rayhyde.nl!
