## What is Ångström, the unit converter?

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 :-)

### 5/5 — Great converter

*2024-01-04, version 1.11.1*

I’m using the app for more than 2 years so far, it’s a great way to convert measures from imperial to metric and vice versa. Never failed me. Especially when most people choose to look up those things on the internet this app is a life savior when you don’t have a stable connection.

### 5/5 — Easiest conversions in the App Store

*2023-11-19, version 1.11.1*

Angstrom is by far the quickest and easiest unit conversion app in here. Nothing else is as easy and being able to immediately type your starting quantity. Half the time it guesses your target unit right away, if it doesn’t you just keep typing or pick from the list. Dead simple, perfectly executed.

Don’t listen to old reviews saying it doesn’t have UK imperial or nautical measures. Not sure if they were accurate when written but it definitely has them all now.

### 5/5 — Using it for years

*2022-01-25, version 1.11.1*

This is the best converter ever. The one ultimate converted you’ll ever need. Thank you developers, this product is great.

### 5/5 — Finally got rid of all my other conversion apps

*2020-11-25, version 1.11.1*

This is The One. It’s faster than any others and has every conversion I can think of / have ever needed. I do some weird stuff at my job and for my hobbies, so I had built a collection of conversion utilities that were each good for certain things. All but Angstrom have been deleted.

Give it a try - that’s the only way you’ll know if it works for you.

### 3/5 — Apple Watch app is dictation only

*2019-09-15, version 1.10*

I got this app primarily for the Watch. 
The interface consists solely of dictation, as far as I can tell. 
If I wanted unit conversions by voice, I’d use Siri! 
No controls at all? The Watch app is useless to me. But the iPhone version is excellent.

### 5/5 — Love the design

*2019-03-09, version 1.10*

It makes all the difference!

### 4/5 — Great tool but keep it up to date with latest SDK

*2018-12-28, version 1.9.2*

Will be good if this app has extensions like widgets, Siri, etc .

### 3/5 — Mixed feelings

*2017-09-29, version 1.9.1*

The UI is beautiful and really intuitive, you have to pay to unlock most conversion units. The only thing wrong is it lacks UK imperial measurements like pounds and ounces and only has US pounds. Also the app name means nothing to me and makes the app hard to find. I would encourage the developer to localise the name of the app and also improve the English translations.

### 5/5 — Still the Betsy currency & unit converter

*2017-06-08, version 1.9.1*

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.

### 5/5 — Excellent app

*2017-04-13, version 1.9.1*

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