* Centimeter is a unit of measurement: A centimeter is a unit used to measure length or distance. It's a tool we use to quantify how big something is.

* Properties of matter describe its characteristics: Properties of matter describe how a substance behaves, such as its density, melting point, color, or chemical reactivity.

Think of it this way:

* Matter: The stuff that makes up everything in the universe (water, wood, air, etc.)

* Property: A characteristic of that matter (color, density, etc.)

* Centimeter: A unit of measurement we use to describe the size of that matter.

So, while we might use centimeters to measure the size of a piece of matter, the centimeter itself is not a property of that matter.
