Which of the following would be appropriate to measure in centimeters? the distance between Philadelphia and New York City, the length of a paperclip, the height of a standard ceiling, the yearly increase in a child's height or the width of a swimming pool

To measure the length or height of something which is a little smaller we prefer to use centimeters.

Lets look at each of the options one by one.

1. Distance between Philadelphia and New York, it is roughly about 94.1 miles which will be way too big of a number if converted in to centimeters (it will be 15000000 cm).

2. Length of a paperclip, this is something that is a considerable length and can be measured in centimeters. Usually a paper clip measures around 3-4 centimeters.

3. Height of a standard ceiling, while constructing something we measure height or length or the width of a floor in feet.

4. Yearly increase in a child's height, that can be measured in centimeters but often we use inches.

5. Width of a swimming pool is also conventionally measured in feet.

So, it is the length of a paperclip and the yearly increase in a height of a child are two things that can be measured in centimeters.
