Tell us the goal - we'll tell you what it takes. Unit conversions checked against primary sources, plus calculators for money, school, kitchen, home, health, daily life, and travel. For instance:
Type a conversion the way you would actually say it, and get the answer, every equivalent unit, and a real sense of how big that is. Type it, say it, or pick it from a list. Nothing is sent anywhere.
Listening… say something like "26 miles to km"
More things your numbers haven't told you
Each of these started as someone's real question - and the answer turned out to be worth knowing.
Six small decisions that add up to something that feels obvious once you've used it.
Input
Type it like you'd say it out loud. Fractions, casual phrasing, and “how many” questions all work.
Output
Every unit shown at once. Tap any row to make it the new target.
Meaning
Every result anchored to something real, like a marathon, a DVD, or a Big Mac.
Ambiguity
Regional differences flagged automatically, with every reading shown side by side.
Precision
Exact defined ratios, adjustable from 2 significant figures to 12.
Decisions
It's not just conversion. Money, school, kitchen, home, daily life, and travel calculators - built to solve for the goal you're after, not just crunch a number you already have.
