This math topic practices conversion of metric length units with decimals from larger to base units. Problems involve converting meters to hectometers, decimeters to meters, meters to millimeters, hectometers to meters, millimeters to meters, and similar variations. It tests understanding of metric unit prefixes such as kilo-, hecto-, deca-, deci-, centi-, and milli-, focusing on accurately executing conversions that incorporate decimal placement shifts while maintaining unit consistency.
