The centimeter (symbol: cm) is a unit of length equal to exactly one-hundredth of a meter (1/100 m or 0.01 m). It's also equal to exactly 10 millimeters.
The centimeter is part of the International System of Units (SI) and uses the metric prefix "centi-" meaning one-hundredth (from Latin centum, "hundred").
Mathematical Relationships
1 centimeter equals:
- 10 millimeters (mm)
- 0.01 meters (m)
- 0.00001 kilometers (km)
- 0.393701 inches (in)
- 0.0328084 feet (ft)
Key conversion:
- 1 inch = 2.54 cm exactly (this is the official international definition established in 1959)
Why Centimeters?
While the meter is the official SI base unit for length, centimeters are more practical for everyday measurements:
Too small for meters, too large for millimeters: A person who is 1.75 meters tall is more commonly described as 175 centimeters in metric countries. Writing "1.75 m" requires decimals; "175 cm" uses whole numbers.
Human-scale convenience: Most objects people interact with daily—clothing, screens, body measurements, food items—fall naturally into the 1-100 cm range.
Avoids decimal confusion: "15.2 cm" is clearer than "0.152 m" for most people.
The Stadion (Ancient Greek: στάδιον, plural: στάδια, stadia) was a prominent ancient Greek unit of length. Its primary basis was the standard length of the track in a Greek stadion (stadium) structure, the venue for footraces and other athletic events.
Like many ancient units, its precise length varied depending on the specific location (polis) and time period, as different stadiums had slightly different track lengths. However, it was generally understood to be 600 Greek feet (podes). Since the Greek foot itself varied, so did the stadion.
Commonly cited values include:
- Olympic Stadion: Approximately 192.27 meters (m) or about 630.8 feet (ft). Based on the stadium at Olympia.
- Attic (Athenian) Stadion: Often estimated around 185 meters (m) or about 607 feet (ft). This is a frequently used general approximation.
- Ptolemaic (Egyptian) Stadion: Used later, sometimes estimated around 157.5 meters (m).
Note: The Centimeter is part of the metric (SI) system, primarily used globally in science and trade. The Stadion belongs to the imperial/US customary system.
History of the Centimeter and Stadion
French Revolution and the Birth of the Metric System
1790s: Revolutionary Innovation: The centimeter was born from the French Revolution's ambition to create a rational, universal measurement system based on nature and decimal mathematics.
The Meter Foundation: In 1791, the French Academy of Sciences defined the meter as one ten-millionth (1/10,000,000) of the distance from the equator to the North Pole along the meridian passing through Paris. The centimeter automatically followed as 1/100 of this meter.
Latin Roots: The prefix "centi-" derives from the Latin centum (hundred), making "centimeter" literally "hundredth of a meter."
1795 Official Adoption: France officially adopted the metric system on April 7, 1795, including the centimeter as a standard subdivision of the meter.
CGS System: The Centimeter's Scientific Era
1874: The Centimeter-Gram-Second System: British scientists James Clerk Maxwell and William Thomson (Lord Kelvin) promoted the CGS system, which used:
- Centimeter for length (instead of meter)
- Gram for mass (instead of kilogram)
- Second for time
Scientific Dominance: The CGS system became the preferred standard for physics and chemistry throughout the late 19th and early 20th centuries. Many scientific formulas and units were developed using centimeters.
Legacy Units: Several units still reflect the CGS heritage:
- Poise (viscosity): measured in gram/(centimeter·second)
- Erg (energy): gram·centimeter²/second²
- Gauss (magnetic field): CGS unit for magnetic flux density
Transition to SI and the Modern Era
1960: The SI System: The International System of Units (SI) was officially established, promoting the meter-kilogram-second (MKS) system instead of CGS.
Centimeter's Continued Relevance: Despite the official SI preference for meters, centimeters remained dominant for everyday measurements because:
- They're more practical for human-scale objects
- They avoid decimals for most common measurements
- They're familiar and intuitive
Global Adoption: Today, 195 of 198 countries use the metric system, with centimeters as the standard for body height, clothing, and everyday measurements. Only the United States, Myanmar, and Liberia officially use non-metric systems.
The stadion was a fundamental unit in the Hellenic world, dating back to at least the Archaic period (c. 800–480 BCE).
- Origin: Directly tied to the length of the stadion footrace, which was the premier event at the ancient Olympic Games and other Panhellenic games. The track length became a standard measure.
- Variability: Different major sites (Olympia, Delphi, Athens, Epidaurus) had stadiums of slightly different lengths, leading to regional variations of the stadion unit. The 600-foot standard was common, but the length of the 'foot' differed.
- Geographical Measurement: It became the standard unit for measuring larger distances, such as travel routes between cities or the dimensions of territories. Historians like Herodotus and geographers like Strabo used it extensively.
- Eratosthenes' Calculation: Most famously, Eratosthenes of Cyrene (c. 276–194 BCE) used the stadion to estimate the Earth's circumference with remarkable accuracy for his time. His result depended crucially on the specific stadion length he assumed (likely the Attic or Egyptian stadion).
- Roman Influence: While the Romans adopted their own system (based on the passus and Roman mile), Greek units like the stadion continued to be understood and sometimes used in the eastern parts of the Roman Empire and referenced by Roman writers like Pliny the Elder when discussing Greek geography.
- Decline: With the decline of the Greek city-states and the dominance of Rome, followed by later measurement reforms, the stadion gradually fell out of practical use, eventually being entirely superseded by Roman, Byzantine, and later metric or imperial units.

- Geography & Cartography: Measuring distances between locations, the size of regions, and geographical features in the Greek world.
- Astronomy: Used by figures like Eratosthenes and Ptolemy for astronomical distances and calculations (e.g., Earth's circumference, distances to celestial bodies).
- Architecture & Urban Planning: Sometimes used for measuring large structures or city dimensions.
- Historical Texts: Crucial for understanding distances mentioned in ancient Greek literature, historical accounts (like Thucydides or Herodotus), and scientific treatises.
Additional Unit Information
About Stadion (stadion)
How long was a stadion?
There was no single, universal length for the stadion. It varied by location and era, typically defined as 600 Greek feet (podes), but the length of the foot varied. Key estimates include:
- Olympic Stadion: ~192 meters (~631 ft)
- Attic (Athenian) Stadion: ~185 meters (~607 ft) - Often used as a general average.
- Ptolemaic Stadion: ~157.5 meters (~517 ft) When interpreting ancient texts, the specific context or author might suggest which stadion length is most appropriate.
How many Greek feet were in a stadion?
A stadion was typically defined as 600 Greek feet (podes).
How did the stadion relate to the Roman mile?
The relationship is not exact due to the variability of the stadion. However, Roman writers often used approximations. A common equivalence was 8 stadia ≈ 1 Roman mile (mille passus). Using the Attic stadion (~185 m) gives 8 * 185 m = 1480 m, which is very close to the standard Roman mile of ~1480 meters.
Is the stadion an SI unit?
No, the stadion is not an SI unit. It is an ancient Greek unit of length. The SI base unit for length is the meter (m).
Is the stadion still used today?
No, the stadion is obsolete and not used for any modern measurements. Its significance is purely historical, essential for classical studies, archaeology, and the history of science (especially geography and astronomy).
Is the stadion related to modern stadiums?
Yes, absolutely. The English word "stadium" directly derives from the Greek stadion, referring originally to the unit of length and then to the structure built to that length for footraces.
