Doing it without a converter

Most converters make you fill in two boxes. Jotal lets you write the calculation the way you'd say it — 20 gal in l — and keep going on the next line. Units carry through your working, so you can write 20 gal in l + 5 L or total a column of mixed units and get a sensible answer.
