Why this one?

Because the other converters are a mess. Ads stacked on ads, popups asking if you want to "stay updated," a cookie banner the size of a small country. You came here to find out how many cups are in a liter, not to negotiate with seventeen tracking partners.

So we built this. Type a number, see the answer. Every page also has the formula, a reference table, and a little diagram so you can see the size difference at a glance. If you're a baker, our cooking conversions actually account for the fact that a cup of flour and a cup of sugar weigh different amounts (which most converters somehow miss). If you're a maker, the trade pages handle drill bits and wire gauges without rounding them wrong. If you're a student, the formulas are right there so you can show your working.

Type 2 1/2, it gets it. Type 5'10", it gets it. That's it. That's the whole pitch.
