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.
