Along with it are a ton of unit and currency conversions. It boasts support for 160 currencies, various mathematical and measurement conversions, and even simpler stuff like cooking conversions.

This one is arguably the best financial calculator on mobile. You can calculate all kinds of stuff like various loans, mortgage tax savings, 401k contributions, credit card payments, and other stuff. It won’t convert pounds to grams, but it does have a currency converter. We like this one because it’s a one-stop-shop for financial calculations and the currency converter is a cherry on top. Everything is available offline. You only need to connect to update the currency conversion rates.

Google Search

Price: Free

There are many great unit converters. However, many people simply turn to a simple Google Search query. It works perfectly fine. You can convert almost anything you can think of. That includes things like currency and cryptocurrency. It’s doable one of two ways. You can open your favorite browser, head to Google, and type in your query. Alternatively, you can just use Google Assistant and ask for a conversion. This should work for most things. However, folks who need a history of their previous calculations may be better serviced with a different app on the list.

Smart Tools Unit Converter

Price: Free / $2.50

Smart Tools is a developer on Google Play with a variety of tools. One of them happens to be a unit converter. The UI feels a little bit old, but otherwise the app works perfectly well. Some of the features include four categories, various units to convert between, and currency conversion as well. The free version has advertising that people seem to not enjoy, but the premium version isn’t too expensive. Our only complaint is we hope future updates bring even more units of measurement to convert.

Text Converter

Price: Free / $0.99

Text Converter is a bit of a wild card on this list. It does conversions, but not the kind you’re thinking of. It can translate text to various other types of text. We’re not talking about language translation. Instead, it’ll convert standard text to ASCII, binary, hex, octal, and various others. You can also do quirky things like Morse Code, add various text styles, and even those fun decorative texts you see online sometimes. It’s the only converter on the list that does this and we included it because it’s a different type of conversion.

Bonus: Unit Converter Ultimate

Price: Free

The app comes with a variety of conversions, including currency conversion. The UI is super basic, but functional and fairly easy to use. It aims to keep things as simple as possible so you can just convert your stuff and get on with your life. The app is entirely free, open source, and it works on versions of Android as far back as 4.0.
