What do we call amounts that are expressed differently using different units of measure?

The correct answer is equivalents. Equivalents refer to amounts that are expressed in different units but represent the same quantity. For example, 1 foot is equivalent to 12 inches, or 1 liter is equivalent to 1000 milliliters. Understanding equivalents is essential, particularly in fields like cooking, science, and various forms of measurement, where different units may be used interchangeably without altering the actual quantity being described.

Proportions are mathematical statements that show the equality of two ratios, while conversions involve changing a measurement from one unit to another. Ratios compare two quantities, indicating how much of one there is compared to another. While conversions and ratios relate closely to the concept of equivalents, they do not specifically describe the idea of different units representing the same amount.
