Convert 7200 millimeters to meters.

• A. 7.2 m
• B. 72 m
• C. 0.72 m
• D. 720 m

Answer: (A)

Understanding how to convert millimeters to meters relies on the fact that 1 meter equals 1000 millimeters. To convert, divide the number of millimeters by 1000 (or move the decimal three places to the left). For 7200 millimeters, moving the decimal three places left gives 7.200, which is 7.2 meters. So the correct result is 7.2 m. The other options come from shifting the decimal a different number of places, which doesn’t match the 1000-to-1 relationship between millimeters and meters.
