This math topic focuses on applying map scale conversions in a metric context, particularly dealing with scales like 1:10, 1:100, and 1:1000. The problems require converting measurements such as centimeters and millimeters from a map scale to actual distances. They involve multiplying by powers of ten up to less than 1000, converting within the same metric units (centimeters to centimeters, millimeters to millimeters). This set of problems helps to practice and reinforce skills in measurement conversion and understanding map scales.
