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 Royal Cubit (Ancient Egyptian: meh nesut) was the primary ancient Egyptian standard unit of linear measure. It was based on the length of the forearm from the elbow to the tip of the extended middle finger, plus the width of the palm. It is considered one of the earliest attested standard units of measurement.
The Royal Cubit was typically divided into 7 palms (shesep), with each palm further divided into 4 digits or fingers (djeba), totaling 28 digits. Its length varied slightly over time and location but is generally accepted to be approximately 52.3 to 52.9 centimeters (about 20.6 to 20.8 inches). A common average value used is 0.524 meters.
A shorter Common Cubit or Short Cubit (Ancient Egyptian: meh sherer) also existed, measuring 6 palms (24 digits), approximately 45 cm.
Note: The Centimeter is part of the metric (SI) system, primarily used globally in science and trade. The Cubit (Royal/Egyptian) belongs to the imperial/US customary system.
History of the Centimeter and Cubit (Royal/Egyptian)
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 Royal Cubit emerged very early in Egyptian history, likely during the Predynastic or Early Dynastic Period (before 3000 BCE). Its standardization was crucial for the large-scale construction projects undertaken by the pharaohs.
- Early Standardization: It represents one of history's first successful attempts at creating and maintaining a standard unit of length, essential for architectural precision and administrative consistency.
- Cubit Rods: Physical standards, known as cubit rods, were created from durable materials like wood, slate, or granite. These rods were often inscribed with subdivisions (palms, digits, and sometimes fractions of digits) and sometimes bore dedications or official insignia. Examples have been found in tombs, such as that of Tutankhamun, and likely served as official benchmarks.
- Monumental Construction: The Royal Cubit was the fundamental unit used in the design and construction of temples, palaces, and most famously, the pyramids. The precise dimensions of structures like the Great Pyramid of Giza reflect careful measurement using this standard.
- Longevity: The Royal Cubit remained the standard measure in Egypt for millennia, from the Old Kingdom through the Ptolemaic period and into Roman times, demonstrating remarkable stability.

Additional Unit Information
About Cubit (Royal/Egyptian) (cubit)
How was the Royal Cubit standardized?
Standardization was achieved through the creation and maintenance of master cubit rods. These physical exemplars, often made of durable stone like granite, were likely kept in major temples or administrative centers. Officials and craftsmen would use copies made from these masters for practical work. The rods themselves were meticulously marked with the primary divisions of 7 palms and 28 digits, often including finer subdivisions. This system ensured consistency across large projects and different regions of the kingdom.
What is the difference between a short cubit and a royal cubit?
The two main cubit measures in ancient Egypt were:
- Short Cubit (meh sherer): Measured 6 palms (24 digits), approximately 44.7 to 45 cm (around 17.6 inches). It represented the distance from the elbow to the tip of the thumb or closed fist. It was likely used for more common, everyday measurements of cloth, goods, or smaller objects.
- Royal Cubit (meh nesut): Measured 7 palms (28 digits), approximately 52.3 to 52.9 cm (around 20.6 inches). It was the length from the elbow to the tip of the middle finger plus one palm width. This was the official standard used for monumental architecture, land surveying, and significant state projects. It likely held a higher status and was associated with the pharaoh and divine order.
How long was the Royal Cubit?
The Royal Cubit was approximately:
- 0.523 to 0.529 meters (m)
- 52.3 to 52.9 centimeters (cm)
- 20.6 to 20.8 inches (in)
- Roughly 1.72 feet (ft)
A value of 0.524 m is often used as a representative average.
Is the Cubit still used today?
No, the ancient Egyptian Cubit (both Royal and short) is obsolete. It has not been in practical use for centuries, having been replaced by other measurement systems and ultimately by the metric system. Its relevance today is purely historical, archaeological, and academic.
Is the Cubit an SI unit?
No, the Cubit is not an SI unit. It is an ancient, traditional unit of measurement originating in Egypt. The SI base unit for length is the meter (m).
