Unitap - Unit Converter
Unit Converter, All at Once
Free · Designed for iPad. Not verified for macOS.
Type one number and read every unit of the same kind at once. Pin the units you use most to build your own conversion sheet. Conversions work offline.
Type one number. Read them all.
Unitap converts a value into every unit of the same category at once. There is no "from" and "to" to pick — the moment you type, the answer is already on screen.
■ Pin what you use
Tap the star and that unit stays right under the input field in large type. From the second time on, you just type the number: cups → ml and tablespoons for cooking, inches → cm for DIY. It becomes your own conversion sheet.
■ 14 categories, about 195 units
Length, mass, temperature, area, volume, speed, duration, data, pressure, energy, power, angle, fuel efficiency and number bases (2 / 8 / 10 / 16). Traditional Japanese units (tsubo, jo, go, sho, monme, shaku and more) are included.
■ Conversions work offline, no account
Every conversion happens on your device, so it works the same in airplane mode or underground (only the ad banner uses the network). No sign-up, no login.
■ Made for moments like these
- A recipe says "1 cup" and "350°F" and you think in ml and °C
- Overseas listings and drawings use inches, lb and sq ft
- You need GB vs GiB, or kB vs KiB, converted correctly
- Imperial units slow you down every time
■ How to use
1. Pick a category from the chips at the top
2. Type a value (tap the unit button to change the input unit)
3. Tap a row to copy the value, tap the star to pin it
Numbers are formatted with grouping separators and sensible significant digits, and unit names follow your device language.
