My child’s school doesn’t teach inches (or centimeters). Can I manually adjust which ruler my child uses?

While there isn't currently a way to choose between only using inches or only using centimeters, we may consider adding this feature in the future.

For reference, the Math Wizard and the Secrets of the Dragons game automatically switches between centimeters and inches depending on which ruler will come up with a whole number. This is intended to make the math more accessible for children ages 6-8.
