Quantity Meaning and Definition in Wikipedia

Quantity or amount is how much of something there is that can be counted or measured.

Whole numbers (1, 2, 3…) are used to count things. This can be done by pointing to each one. As things are pointed to, a number is said. Start with the number one. Each time another thing is pointed to, the next whole number is used. When the last thing in a group it pointed to, that number is the quantity of the group.

Measuring is done with a ruler or a machine. We put a ruler next to a thing to measure how long it is. We put things on a scale to measure their mass. Other machines are used to measure temperature, speed, or electricity.

When measuring things, a whole number might not be the best answer. A distance might be longer than 5 meters, but less than 6 meters. Meter sticks are marked off in parts of a meter. Decimals are formed by marking off a ruler in ten equal parts. Each part is a tenth. 5.2 meters is a little bit longer than 5 meters. 5.7 meters is a little bit shorter than 6 meters. Each of these tenths can be marked with ten smaller parts. The one hundred centimeters on a meter stick are done this way.
