1) Conversion factor: The main difference between cm³ and liters is the conversion factor. 1 liter is equal to 1000 cm³. This means that to convert from cm³ to liters, you divide by 1000, and to convert from liters to cm³, you multiply by 1000.

2) Units of measurement: cm³ is a unit of volume in the metric system, specifically the cubic centimeter. It is commonly used to measure the volume of small objects or substances. Liters, on the other hand, are also a unit of volume in the metric system, but they are used to measure larger volumes, such as the capacity of containers or the volume of liquids.

3) Size of measurement: Due to the conversion factor, cm³ is a smaller unit of measurement compared to liters. 1 liter is equivalent to 1000 cm³, so 1 cm³ is only 0.001 liters. This means that when measuring the same volume, the numerical value in cm³ will be much larger than in liters.

4) Common usage: Liters are more commonly used in everyday life for measuring volumes of liquids, such as in cooking or filling up a gas tank. On the other hand, cm³ is often used in scientific or technical contexts, such as measuring the volume of a solid object or calculating the displacement of an engine.
