Final answer:
A millimeter is one thousandth (1/1000) of a meter, meaning that there are 1000 millimeters in a meter. The metric system relies on this relationship for length measurements and conversions.
Step-by-step explanation:
The relationship between a millimeter and a meter is that a millimeter is one thousandth (1/1000) of a meter. This means that 1 millimeter (mm) is equal to 0.001 meter (m). To convert kilometers to meters to millimeters, we use the conversion factor of 1000 meters for every 1 kilometer and 1 millimeter for every 0.001 meter. In the metric system, units of length such as centimeters, meters, and kilometers are derived from the meter. The prefix 'milli-' in 'millimeter' represents a factor of 1/1000, which indicates that there are 1000 millimeters in one meter.
Here are some other metric unit conversions related to length:
- 1 meter (m) = 1000 millimeters (mm)
- 1 centimeter (cm) = 10 millimeters (mm)
- 1 kilometer (km) = 1000 meters (m)
Understanding these relationships and conversion factors is essential for accurately measuring and converting distances in the metric system.
