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 Li (里) is a traditional Chinese unit of distance, often translated as the "Chinese mile". It represents a significantly longer distance than the Chi (Chinese foot) and was historically the primary unit for measuring travel distances and land divisions over large areas.
Traditionally, the Li was defined in relation to smaller units like the Bu (步 - pace) or the Zhang (丈), and ultimately the Chi (尺). Common historical relationships included:
- 1 Li = 300 or 360 Bu
- 1 Bu = 5 or 6 Chi
- Therefore, 1 Li could equal 1500 or 1800 Chi.
- Alternatively, 1 Li = 150 Zhang (since 1 Zhang = 10 Chi).
Like other traditional Chinese units, its exact length varied considerably across different dynasties and regions. The modern standardized value, adopted for convenience and integration with the metric system, defines the Li as exactly 500 meters (0.5 kilometers).
Note: The Centimeter is part of the metric (SI) system, primarily used globally in science and trade. The Li (Chinese) belongs to the imperial/US customary system.
History of the Centimeter and Li (Chinese)
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 Li has been a fundamental unit of distance in China for thousands of years, used since at least the Zhou Dynasty (c. 1046–256 BC). Its length was not constant, often changing with administrative reforms or shifts in the standard length of the base unit, the Chi.
- Early Dynasties: The length fluctuated. For example, during the Han Dynasty, based on a Chi of ~23.1 cm and a definition of 1 Li = 300 Bu = 1800 Chi, the Li would have been approximately 415.8 meters. Other periods might have used different definitions or Chi lengths, leading to Li values ranging roughly from 300 to over 500 meters.
- Standardization Efforts: Various dynasties attempted to standardize measurements, but regional variations often persisted. The Li was crucial for imperial administration, defining tax districts, postal routes, and military logistics.
- 20th Century Standardization: Following the establishment of the Republic of China, efforts were made to align traditional units with the metric system. In 1929, alongside the standardization of the Chi as 1/3 meter, the Li was officially defined as 1500 Chi, which resulted in exactly 500 meters (0.5 kilometers). This standard was maintained by the People's Republic of China.
The Li's historical significance lies in its role as the standard measure for long distances, shaping perceptions of geography and travel within China and neighboring East Asian cultures influenced by the Chinese system.

When to Use li
While officially replaced by the kilometer for most purposes, the Li retains significance:
- Historical Measurement: Essential for understanding distances mentioned in historical texts, maps, administrative records, travelogues, and descriptions of large-scale projects like the Great Wall or canal systems.
- Geographical Names: Many place names in China incorporate "Li" (e.g., 十里堡 - Shilibao, "Ten Li Fort"), often reflecting historical distances or significance, even if the modern distance doesn't match precisely.
- Cultural References: The Li features prominently in Chinese idioms, proverbs, literature, and poetry, often symbolizing long journeys or vast distances. A famous example is 千里之行，始於足下 (qiān lǐ zhī xíng, shǐ yú zú xià - "A journey of a thousand li begins with a single step").
- Informal Usage: In some rural areas or among older generations, "Li" might still be used informally to refer to a distance of approximately half a kilometer. It can also be used colloquially as a direct synonym for 0.5 km.
- Mapping: Older maps and surveys frequently used the Li.
Additional Unit Information
About Li (Chinese) (li)
How long is a Li?
The length of the Li varied significantly throughout history, typically ranging from about 400 to over 500 meters. The modern standardized value (since 1929) is:
- Exactly 500 meters (m)
- Exactly 0.5 kilometers (km)
- Approximately 0.3107 miles (mi)
- Approximately 1640.42 feet (ft)
- Approximately 546.81 yards (yd)
How was the Li historically defined?
It was typically defined based on smaller units:
- 1 Li = 300 or 360 Bu (步 - paces)
- Since 1 Bu was often 5 or 6 Chi (尺 - Chinese feet), this meant *1 Li = 1500 or 1800 Chi.
- Alternatively, 1 Li = 150 Zhang (丈), where 1 Zhang = 10 Chi. The variation depended on the specific dynasty, region, and the prevailing standard length of the Chi.
How does the Li relate to the Kilometer?
The modern standardized Li is defined directly in relation to the kilometer:
- 1 Li = 0.5 Kilometers
- 1 Kilometer = 2 Li
Is the Li an SI unit?
No, the Li is not an SI unit. It is a traditional Chinese unit of distance. The SI base unit for length is the meter (m), and the commonly used unit for larger distances is the kilometer (km).
Is the Li still used today?
Officially, China uses the metric system (kilometers and meters) for all legal, commercial, scientific, and administrative purposes. However, the Li continues to be used in:
- Historical and cultural contexts.
- Geographical place names.
- Idioms and literature.
- Informal conversation, often meaning exactly 0.5 km.
Is this related to the surveying Link (li)?
No, they are completely different and unrelated units, despite the similar symbol in some contexts.
- The Chinese Li (里) is a traditional unit of distance, standardized at 500 meters.
- The Gunter's Link (li) is a historical surveying unit from the imperial system, equal to 0.201168 meters (or 7.92 inches).
