Meters or yards
There is no "unit of measurement for a plastic block". The SI has units of length, area, volume, mass, tensile strength, etc.; please clarify what aspect of the plastic block you want to measure.
Yards

The measurement of a city square block is not exact as it will vary from city to city. However, as a rough guide, in Portland, Sacromento and Houston a standard block would be 260 feet by 260 feet.

44,000
Yards
There is 44,560 square feet in one acre of land. A "typical" city block (they can be many different sizes), when calculated by an engineer beginning to work on a new development, is 100,000 square feet. Thus, as a starting point, You could fit .446 city blocks on one acre of land (44,560 / 100,00. Looking at the same question from the other way, it would take 2.24 acres of land for one city block (100,000 / 44,560).
Hectares
cent
It means land or earth measurement.
