In order to be able to use this unit converter, first install all the dependencies via composer:
composer install
After running composer install you should be good to go. There are 3 commands that can be used to do conversions.
Converting distances:
bin/console unit-converter:distance
Converting temperatures:
bin/console unit-converter:temperature

After running any of these comments in the project directory. You'll get a CLI wizzard to do the conversions.
