How many millimeters are in one meter?

One meter is defined as being equivalent to 1000 millimeters. This is based on the metric system, where the prefix "milli-" indicates a factor of one thousandth. Therefore, when converting meters to millimeters, you multiply the number of meters by 1000.

In the metric system, the relationship is straightforward: 1 meter = 1000 millimeters. This conversion is crucial for understanding measurements in fields such as nursing and healthcare where precise measurements are often required.
