Continuous Quantity

A quantity that can take any value within a given interval is a continuous quantity. Such quantities are not limited to specific, separate values, and they can be measured very precisely. Length, time, temperature, weight, and age are examples of continuous quantities.

Here, each point on the number line corresponds to a specific age, and the line itself represents the possible ages. A person's age can be any real number, depending on the precision of the measurement. In using whole years, someone's age might be said to be 5 years old. With more precise measurements, age could be expressed as 5 and a 12 years, 8 years and 2 months, or an age like 8 years and 88 days.
