This math page focuses on practicing conversions between different metric units of length, including millimeters (mm), centimeters (cm), meters (m), and kilometers (km). Students will solve problems requiring converting measurements from one unit to another. Remind students that 1 cm = 10 mm, 1 m = 100 cm, and 1 km = 1,000 m. A few challenge problems on this worksheet will include decimals, such as solving 6.00005 m = ________ cm. To solve the problem of converting 6.00005 meters to centimeters, students need to know that there are 100 centimeters in one meter. This means when you want to change meters to centimeters, you multiply by 100. So take 6.00005 and multiply it by 100. Therefore, 6.00005 meters becomes 600.005 centimeters.
