What is a Cubit (Royal/Egyptian) and a Toise?
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.
The Toise is an historical French unit of length, used extensively before the adoption of the metric system. It was legally defined as 6 pieds du roi (French royal feet).
Based on the standard established for the pied du roi, the Toise equates to:
- Exactly 1.94903631 meters (m) (based on the 1799 definition of the meter relative to the standard Toise bar)
- Approximately 6.395 English feet (ft)
- Approximately 76.73 English inches (in)
The Toise was further subdivided:
- 1 Toise = 6 Pieds (French feet)
- 1 Toise = 72 Pouces (French inches)
- 1 Toise = 864 Lignes (French lines)
Note: The Cubit (Royal/Egyptian) is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Toise belongs to the imperial/US customary system.
History of the Cubit (Royal/Egyptian) and Toise
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.
The Toise was a fundamental unit of length in France for centuries, used in various fields from the Middle Ages through the Ancien Régime and into the early post-revolutionary period. Its name derives from the Latin tensa, meaning "stretched (arms)", suggesting an origin related to fathom.
Standardization was crucial. The primary standard became the Toise du Châtelet, an iron bar embedded in the wall of the Grand Châtelet fortress in Paris. In 1668, this standard was physically copied by Jean Picard and used for geodetic surveys. Later, a copy known as the Toise du Pérou (or Toise de l'Académie) became the official reference standard for French length measurements. This specific bar was physically used in the famous French Geodesic Missions to Peru (1735–1744) and Lapland (1736–1737), which aimed to measure the length of a degree of latitude near the equator and the Arctic Circle, respectively.
These measurements, based on the Toise, were instrumental in determining the shape of the Earth and ultimately provided the basis for the definition of the meter. The meter was initially defined in the 1790s as one ten-millionth of the distance from the North Pole to the Equator along the meridian passing through Paris, a distance calculated from the geodetic surveys performed using the Toise standard.
The Toise was officially replaced by the meter following the French Revolution and the establishment of the metric system in France, formally adopted in 1799.
Common Uses for cubits and toise
Explore the typical applications for both Cubit (Royal/Egyptian) (imperial/US) and Toise (imperial/US) to understand their common contexts.
Common Uses for cubits
The Royal Cubit was integral to many aspects of ancient Egyptian society:
- Architecture and Construction: Defining building dimensions, column heights, room layouts, and overall structural proportions.
- Land Surveying: Measuring fields for agriculture, taxation, and property boundaries, especially after the annual Nile flood receded.
- Record Keeping: Used in administrative documents, inventories, and calculations.
- Craftsmanship: Measuring materials like stone blocks, timber, rope, and textiles.

- Religious and Funerary Contexts: Cubit rods were sometimes included in tomb equipment, possibly symbolizing order and correctness or serving a practical purpose in the afterlife.
- Historical Texts: The term "cubit" appears in various ancient texts, including the Bible, though the specific length intended (Egyptian Royal, common, Babylonian, etc.) can be context-dependent.
Common Uses for toise
The Toise is now obsolete but was historically essential for:
- Land Surveying: Measuring land areas, property boundaries, and distances for cartography.
- Architecture and Civil Engineering: Designing and constructing buildings, bridges, canals, roads, and fortifications (notably by Vauban). Dimensions of major historical French structures were often specified in Toise.
- Military Engineering: Laying out fortifications, measuring artillery ranges.
- Geodesy and Scientific Measurement: Serving as the standard unit for precise scientific measurements, particularly in astronomy and the crucial 18th-century geodetic surveys that measured the Earth.
- Craftsmanship: Used in various trades requiring length measurements.
Frequently Asked Questions
Questions 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).
