Here's why:
* Centimeter (cm): A standard unit of length in the metric system, widely used in science.
* Gram (g): A standard unit of mass in the metric system, also widely used in science.
* Milliliter (ml): A standard unit of volume in the metric system, essential for measuring liquids in scientific experiments.
Quarts (qt) are a unit of volume primarily used in the US customary system. The scientific community generally prefers the metric system for its simplicity and consistency. While quarts might occasionally appear in some historical scientific data or non-scientific contexts, they are not a standard unit in modern scientific research.
