What is a Centimeter?
The centimeter is one hundredth of a meter — equal to 10 millimeters or approximately 0.394 inches. It appears on most rulers and measuring tapes sold outside the United States and is the standard unit for body measurements such as height and waist size. A typical adult fingernail grows roughly 3 mm (0.3 cm) per month. Centimeters are also used for paper sizes and small furniture dimensions worldwide.
What is a Inch?
The inch is a unit of length in the imperial and US customary systems, defined exactly as 2.54 centimeters since the International Yard and Pound Agreement of 1959. It is divided into binary fractions — halves, quarters, eighths, and sixteenths — and remains standard for screen sizes, display resolutions, and construction lumber in the United States. Historically, the inch derived from the width of a human thumb or three barleycorns placed end to end. A US letter sheet of paper measures 8.5 inches wide.
