What do cc's and ml's measure?

1. Time duration

2. Volume

3. Weight

4. Length

The correct answer is: Volume

The measure of cc's (cubic centimeters) and ml's (milliliters) pertains to volume. Both cc's and ml's are units of measurement used to quantify the space occupied by a substance, typically liquids. One cubic centimeter is equivalent to one milliliter, making these units interchangeable in practice, especially in medical and laboratory settings. Volume measurements are critical in various contexts such as dosing medications, measuring fluid intake or output, and conducting scientific experiments. Understanding how to accurately measure and convert between these units is essential for healthcare professionals and anyone working in fields that require precise volume calculations. The other options—time duration, weight, and length—are distinct measurements that do not relate to cc's and ml's. Time duration is measured in seconds, minutes, or hours; weight is quantified in grams or pounds; and length is expressed in meters or inches, all of which serve different purposes in measurement and require different units of measurement.
