Units

Units is a powerful unit-aware calculator.
It can convert between ≈2,400 different units, making it an ideal unit converter for complex or obscure tasks. It has everything
- from basic distances, volumes and temperatures, to kitchen weight-to-volume conversions, to chemistry
- and physics-specific units and equations.

Units can convert between dimensions, for example, multiplying distances to get area and volume.

Units is licensed under the GPLv3 (GNU GPL version 3) and is inspired by GNU Units.

This is the only app I've found that is actually a unit-aware calculator. All the others are just fixed-domain unit converters. They can't do simple calculations like 3 amps x 12 volts = 36 watts. This app works fine in Android 11. Please consider updating the manifest so that it will actually appear in the play store search results.

An outstanding APP witha tiny footprint. This sucker will convert units even into ovscure archaic & scientific units. Extremely intuitive & easy to use. One if the best APPs you'll ever use. Zero bugs. A must have! 👍👍

The Linux/Unix "units" command in Android app form. I use it all the time with great success.

Works pretty well, but temperature conversion may not work as expected. E.g. have to do tempF(32).

Been looking for something like this (even considered trying to port qalculate) - particularly like the autocomplete. Needs more and useful data units (technically gigabytes is correct but desperately need GiB etc). Ideally more scientific functions on advanced keyboard without needing to use autocomplete so could replace calculator.

I bought a new phone nd was finding this app ....I hv to scroll down a bit longer to found dis app ...there are still many apps of converter here on google play bt it is only this app on which I can trst by heart......this app helps me alot to solve problems of Bullshit physics .....thnxx fr giving us such a nc app

For a long time, I've wanted to have the power of Google's search calculator on my phone. Come to find out, it's backed by GNU units, which is also the basis of this app. Adding in the interface that improves on the built-in calculator, and you've got the best back-of-the-envelope calculator available on the play store. Quick question for the developer: does it do a periodic units_cur update to make sure the currency exchange rates are up to date?

Having been spoiled by the power of the Unix Units program, I went looking for a clone of it. Found it finally! Great! By the way, it doesn't just convert, it does arbitrary calculations like "3 ft + 2 in".

Awesome. Unlike the tons of other converters, this one can do things like converting time and distance to velocity which is hugely helpful. FLOSS too.

I use it daily for stuff ranging from fuel consumption to astrophysics. You can input your mass in pounds divided by squared height in inches and ask for result in kg/m2, and it will figure it out and give you your BMI

Was looking for something that allows you to build complex unit structures on the fly like Univerter did for Windows. Seems to work very well. Input method is pretty straightforward and efficient.

Could have been simplified a great deal but overall a very good option especially for a wide array of different measurements common and rare.

It has a terrible interface. It's not set up well at all. You can't select a from unit and a to unit, press convert and get an answer. Nothing is clearly labelled. It's far from intuitive or user friendly. Keep looking.

I like it, but it needs some corrections: 1 GB is not 1000000 kB.

This app knows every concevable unit! Not quite as versatile as the linux command line tool, but still very useful.

Dav. G. Apr 6, 2014     

Units has long been a staple for Unix command line users. It's nice to find it on Android

Jim. S. Apr 11, 2018     

I'm a tech-head. I would suffocate without this app. Many thanks.

Har. R. Jan 19, 2013     

Not immediately intuitive. But worth reading the help: this really is very clever.

Vio. G. Aug 26, 2013     

Great for simple stuff and the only calculator I've seen on android useful for an engineer.

And. K. Nov 1, 2014     

Finally, somebody thought of not reinventing wheel and reusing existing code instead for this task! Should be in the top downloads IMO, but maybe people on Android don't like GPL or too many features :) One feature I miss is possibility to overlay the units database - e.g. to update currency conversions. Also integration e.g. with calculator++ would be nice.

A. G. u. Aug 14, 2014     

It's missing one unit, the cubit. You gotta be careful with orders of operations but that just like any calculator.

Tyl. C. Jun 27, 2013     

I've been using this app for all conversion needs, but today I found it does not have meters per second. What..?

A. G. u. Sep 15, 2011     

Package file incorrectly signed Update won't install.. says package file was not signed correctly...

Fre. B. Apr 6, 2014     

The suggested units make this more handy than the command line version.

Dea. B. Jul 4, 2013     

Will make use of this

A. G. u. Jun 25, 2012     

Don't use it often but it is invaluable on occasions

A. G. u. Sep 17, 2011     

Perfect. I could not ask for more.

A. G. u. Jul 16, 2011     

Would be nice to select colors in settings.

A. G. u. Mar 18, 2012     

Useful and open source.

A. G. u. Feb 22, 2012     

Perhaps need an update.
