What is a Millimeter?
The millimeter is one thousandth of a meter, making it the smallest SI length unit in routine use. Defined exactly as 0.001 m, it equals roughly 1/25 of an inch. Millimeters are the standard for precision engineering, machining tolerances, and clinical measurements. A standard credit card is about 0.76 mm thick, and a human hair averages 0.06–0.08 mm in diameter.
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.
