About these calculators
Not every useful tool belongs to a neat subject. This is where the ones that don't fit anywhere else live — small, sharp utilities that solve exactly one problem and then get out of your way.
Everything here runs entirely in your browser. Nothing you type is sent to a server, nothing is stored, and every tool works the same whether you are online or not once the page has loaded.
