Understanding Centimeters and Millimeters
To comprehend how many millimeters are in one centimeter, it's important to understand the metric system, which is based on powers of ten.
Basic Metric Units
- The metric system includes various units of measurement, such as centimeters (cm) and millimeters (mm).
- 1 centimeter is defined as one hundredth of a meter.
- 1 millimeter is defined as one thousandth of a meter.
Conversion Between Centimeters and Millimeters
- Since 1 centimeter is equal to 10 millimeters, we can express this relationship as:
- 1 cm = 10 mm
- This means that if you have 1 centimeter, it is equivalent to 10 millimeters.
Visualizing the Conversion
- Example: If you have a ruler, notice that the markings for centimeters are larger than those for millimeters.
- Each centimeter on the ruler is divided into 10 smaller segments, each representing a millimeter.
Conclusion
- Therefore, the correct answer to the question "How many millimeters are there in 1 centimeter?" is indeed 10 mm, which corresponds to option B.
- Understanding this conversion is fundamental in measurements, especially in fields such as science and engineering, where precise dimensions are crucial.
