Nikita Tataurov

Units Converter Free is a brilliant application allowing to convert hundreds of measurements grouped into 17 categories. We tried to make our program as user friendly as possible, and now anyone can use it immediately after installation without reading a line from the manual.

Doesn't matter who you are. Almost certainly, from time to time, you face the necessity to make conversions. Units Converter Free will facilitate this process to the simple press of a couple of buttons. So if conversions is the only reason for you to carry a calculator, you can now leave it at home.

Main features of the program:
- very intuitive interface
- clean simple design
- possibility to choose out of categories (angle, area, bits, density, electric current, energy, force, fuel consumption, length, mass, power, pressure, speed, temperature, time, volume and shoe size)
- possibility to quickly switch conversion direction (i.e. miles to km or km to miles). Simply type into the other field

We will constantly improve Units Converter Free and we take seriously all feedback from the users. So if you need some units of measure which are not in our converter now, please write us via Feedback form and they will be added specially for you.

Quick and simple to use! Search for the conversion alphabetically, type in the value and hit the button. That's it!

We chose to organize the conversion factors alphabetically. So, there's no thinking required to figure out what category the conversion you need belongs to. This made finding the conversion you need much faster!

This converter always displays the conversion factor on the screen so it's very clear what is happening when you hit the button. Often we need to know the factor for other things so now it's right there for you to see.

Even though this application was made for ease of use it includes over 1000 conversions, several of which would only be used by engineers and scientists. We included the scientific notation for these users.

You won't find another unit converter in the app store like this!
