Unit Converter

Convert units. That's it. Type a number and read it in every unit of the category at once. No ads, no sign-up, no accounts, and nothing watching what you do.

Twelve categories sit across the top: Length, Weight, Temperature, Volume, Area, Speed, Time, Data, Pressure, Energy, Fuel economy, and Angle. Pick one, type a value, and the whole list updates as you type: every unit, plus the readouts people actually use, like 5′ 6″, 3 lb 4 oz, and 1 h 30 min. Leave the field empty and the list shows 1 of your unit, so it doubles as a reference card.

Or just type what you mean. "72 f", "5 ft 6 in cm", "3 lb 4 oz in kg", "100 km/h to mph": the app works out the category and the units for you.

NEW IN 1.2

• Every unit at once: one value, the whole category, live as you type

• Tap any value to copy it; long-press to pin it to the top, make it the input unit, or see the formula
• Recent conversions, one tap to bring back
• Four new categories: Pressure, Energy, Fuel economy (mpg, km/L, L/100 km), and Angle
• Feet-and-inches, pounds-and-ounces, and hours-minutes-seconds readouts
