Units explained
Foot
A foot is an Imperial and US customary unit of length equal to 12 inches or exactly 0.3048 meters. It is the most commonly used unit of length in everyday measurement in the United States.
The foot's origin is literally the length of a human foot, used as a measurement standard since antiquity. The English foot was standardized at various points in history; the modern international foot (0.3048 m exactly) was fixed by the 1959 International Yard and Pound Agreement.
Feet are used in the US for body height, building dimensions, room sizes, road sign clearances, aviation altitude (feet above sea level), and most everyday distance estimation. The UK uses feet informally for height despite officially being metric.
Used since antiquity; standardized to 0.3048 m exactly by the International Yard and Pound Agreement of 1959. Aviation worldwide uses feet for altitude despite metric adoption elsewhere.
Centimeter
A centimeter is a metric unit of length equal to one hundredth of a meter (1/100 m). It is one of the most commonly used SI sub-units in daily life, especially for measuring small objects, body dimensions, paper sizes, and short distances.
The centimeter emerged from the French metric system established by the French Academy of Sciences in 1793. The metric system introduced decimal-based prefixes (milli-, centi-, deci-, deca-, hecto-, kilo-) to create proportional sub-units of the meter.
Centimeters are the standard unit for everyday measurement in nearly every country outside the United States. They are used for body height, clothing sizes, rainfall, paper formats (A4 is 21 × 29.7 cm), screen dimensions, and most consumer product specifications.
Developed in France during the late 18th century as part of the metric system designed by the French Academy of Sciences. Formally adopted in France in 1795 and ratified internationally through the Metre Convention signed in Paris in 1875.

Worked examples
Example 1 — Convert 1 ft to cm:
1 × 30.48 = 30.48 cm
Example 2 — Convert 100 ft to cm:
100 × 30.48 = 3048 cm
Real-world example — Adult height in metric
A 6-foot-tall person measures 182.88 cm. American expats filling out medical or driver's-licence forms in metric countries convert their height from feet to cm for the local documentation.
6 ft × 30.48 = 182.88 cm
Real-world example — Average doorway height
A 5-foot mark (60 inches) on a wall equals 152.4 cm — useful when planning a home renovation in a country that requires the building permit dimensions in cm.
5 ft × 30.48 = 152.4 cm
Real-world example — Carpet and flooring
A 10-foot run of flooring equals 304.8 cm. International flooring retailers quote material in centimeters and meters; American contractors measuring in feet convert ft to cm to bridge the two.
10 ft × 30.48 = 304.8 cm
