How many millimeters are in a meter?

500
750
1,000
2,000

The correct answer is: 1,000

A meter is a fundamental unit of length in the metric system, and it is defined as being equal to 1,000 millimeters. This relationship is rooted in the metric system's use of powers of ten, where each unit is a multiple of ten of the next. Specifically, one millimeter is one-thousandth of a meter. Therefore, to convert meters to millimeters, you multiply the number of meters by 1,000. Since there is one meter, this results in 1 meter x 1,000 millimeters/meter, which equals 1,000 millimeters. This clear conversion factor is vital in various applications, especially in fields where precise measurements are essential.
