A fingernail’s width, or 10 millimetres, is around one centimetre. A centimeter’s size can also be thought of in terms of inches. An inch is roughly three times smaller than a centimetre.
The metric system of measuring is used to measure centimetres as opposed to the imperial or American systems. The most popular tool for measuring distances, the ruler, has calibrated lines that are denominated into centimetres or inches, making it simple to compare the two systems.
The size of a centimetre in relation to common objects can be useful as well. Utilizing orders of magnitude, or the scale of relationships between numbers, is a more accurate method.
