In everyday use, centimeters measure small objects, clothing dimensions, and small-scale maps. In science and engineering, the centimeter is often used alongside the meter; it remains a practical unit for lengths on the centimeter-to-meter scale.

Conversions commonly used with 5 cm include: 1 cm equals 10 millimeters; 1 meter equals 100 centimeters; 1 inch is approximately 2.54 cm, making 5 cm approximately 1.9685 inches or about 0.164 feet.

History and standardization: The centimeter is part of the metric system, which was developed in the 18th and 19th centuries. The meter, the base unit of length in the system, was originally defined by a physical prototype and later redefined in terms of fundamental constants, such as the speed of light. A centimeter is defined as one hundredth of a meter.

Etymology and usage: The prefix centi- means hundred in Latin, and the symbol cm is used in most contexts. The centimeter is widely used in science, education, manufacturing, and daily life for expressing moderate-length measurements such as dimensions of appliances, paper sizes, and human-scaled objects.
