About UnitCrate

UnitCrate is a unit conversion tool built for people who hate clicking through dropdown menus. Type a value, see every equivalent unit instantly — no dropdowns, no page reloads, no ads.

What we believe

• Show everything at once. Most converters make you pick a target unit from a dropdown. We show all units simultaneously — so you can compare at a glance.
• Speed is a feature. Every page is statically generated. No spinners, no interstitials, no sign-up gates before you get a result.
• Live data where it matters. Currency conversions pull live rates from the ECB via Frankfurter. Cooking ingredient conversions use real density tables, not guesses.
• No clutter. We don't run display ads. We don't upsell premium tiers. The tool is free because it should be.

What we cover

Length, weight, temperature, volume, area, speed, time, data storage, pressure, energy — plus currency (20+ currencies, live rates) and cooking ingredient conversions by weight and volume. More categories are added regularly.
