Ångström, the unit converter

By Alexander Babaev

Open iTunes to buy and download apps.


Convert units, currencies and timezones faster than you type.

Start with the number, then type one or two letters and see the result. Use dedicated numpad to avoid switching keyboards. Forget digging through endless unit categories in urge to find the one you need (although you can do it when in adventure mood). If the number is in your clipboard, we’ll pick it up.

We learn what you convert to make better guesses over time. We keep currency rates updated, but show you approximate values when offline. We support alternative spelling of many units.

Type “45f”, get Fahrenheit converted to centigrade right away. Or maybe you meant feet to meters? We’ll show that, too. We know, by the way, that it’s natural to convert feet to meters, but miles to kilometers.

Get timezones conversion and more units with in-app purchase. Or just show your support by upgrading :-)

What's New in Version 1.9

More units, less bugs.

Now we have 1067 units in 26 categories. New units: gray, centigray, rad, wa, ngan, rai. New timezones: Auckland and Wellington.

What do you think? Upgrade to the full version, if you like Ångström. And we will appreciate your review in the App Store. Also, you can reach us directly at @ilyabirmannet and @bealex.

Customer Reviews

Built for speed

I don't want to have to pick through a long list of categories of conversions... I just want my answer quickly! The simple interface in this app (numeric keypad above the alpha pad) means you just enter the value and units of what you want to convert and most times the app picks the correct conversion for you - if not, then you can select the units you want from a list OR just type them in.

Still the best converter on the store

Super well made and tracks with how my brain works. Just type what you want (with fast and intelligent auto-complete) instead of hunting through long menus of obscure icons.

The fastest and the only useful converter

The only converter fast enough to use it while watching Mythbusters and converting from US units to metric without pausing!
