What does the abbreviation 'cm' represent?

1. Centimeter, equivalent to 1/1000 of a meter

2. Centimeter, equivalent to 1/10 of a meter

3. Centimeter, equivalent to 1/50 of a meter

4. Centimeter, equivalent to 1/100 of a meter

The correct answer is: Centimeter, equivalent to 1/100 of a meter

The abbreviation 'cm' stands for centimeter, which is defined as one-hundredth (1/100) of a meter. In the metric system, the centimeter is a commonly used unit of length that helps in measuring smaller distances and is frequently utilized in various fields, including health, construction, and environmental assessments. The clarity of this unit of measurement is essential as it allows for precision in reporting dimensions, particularly in risk assessments involving lead-based paint where small amounts can pose significant health risks. In contrast, the other options define the centimeter inaccurately in relation to the meter. Understanding the metric system's hierarchy is crucial for correctly applying the units during measurements and calculations.
