Previous

In the applets below you can exercise how to convert lenght (metric) units and area (squared) units.
It is necessary to know relationships between these units and how to multiply and devide decimal numbers by 10, 100, 1000 etc.

1st   Lenght units

From a larger to smaller

In the applet below, first try to figure out what would be the answer, and then click 'the solution' answer to check your answer.
After solving this problem, click the 'Refresh' sign in the right-upper angle of the applet to get a new problem.
When you become sure in solving such problems, go to the next applet.
