"Üben Conversion" lets you practice basic conversion of units.

The app is designed to be as simple as possible. This is great for children as it is super easy to use. The app generates a task with a random length or weight and a target unit - for instance "1.5 km -> m". Enter the value for the target unit and the app shows, whether it was correct or not. If it was not, the correct value is shown.
