Common length units

Centimeter (cm)

Definition: A centimeter (symbol: cm) is one hundredth of a meter (0.01 m). It is a metric unit of length commonly used for small to medium measurements.

History/origin: The centimeter developed as part of the decimal metric system introduced in France in the late 18th century. It quickly became one of the most practical subdivisions of the meter for everyday use.

Current use: Centimeters are widely used for body measurements, school rulers, furniture dimensions, clothing, and household objects in countries that use the metric system.

Nanometer (nm)

Definition: The nanometer is an ultra-small metric length unit. One nm equals 10^-9 meters, so one billion nanometers make a single meter.

History/origin: As scientists began measuring atoms, molecules, light, and microchip features, the metric prefix nano- gave those tiny distances a compact and readable unit name.

Current use: Nm appears in chip process sizes, optical wavelengths, nanoparticle dimensions, DNA and protein measurements, surface coatings, and materials research at near-atomic scale.
