Let's solve each of these unit conversion problems step by step. We'll use the following standard metric conversions:
-
1 meter (m) = 100 centimeters (cm)
-
1 centimeter (cm) = 10 millimeters (mm)
-
1 meter (m) = 1,000 millimeters (mm)
-
1 kilometer (km) = 1,000 meters (m)
-
1 kilometer (km) = 100,000 centimeters (cm)
-
1 kilometer (km) = 1,000,000 millimeters (mm)
