Ångström, the unit converter

By Alexander Babaev

This app is only available on the App Store for iOS devices.


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 1.9.1

Added electric charge (coulombs, amp hours and such). Fixed some bugs. Bitcoin exchange rate should be reliable now. 1069 units in 27 categories.

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

Still the Betsy currency & unit converter

Much quicker to use than every other unit converter I've tried. I love that it keeps currencies updated in the background so I never have to remember to update it before traveling. And there are many elegant details throughout that make this app a pleasure to use. Highly worth it.

Good app for watch

The latest update makes this a great app for the watch. It's easier than finding my phone.

Excellent app

This is a great converting calculator. It has a large amount of data and I recommend it highly.
