What is a Smoot and a Vara?
The Smoot is a non-standard, humorous unit of length created as part of an MIT fraternity prank in October 1958. It is defined by the height of Oliver R. Smoot (MIT class of 1962) at the time of the prank, which was 5 feet 7 inches.
This equates to:
- 67 inches (in)
- 1.7018 meters (m)
- Approximately 1.86 yards (yd)
Unlike standardized units, the Smoot is intrinsically tied to a specific individual's height at a particular moment and serves primarily as a cultural artifact and inside joke, particularly within the MIT community.
The Vara (Spanish and Portuguese for "rod" or "pole") is a traditional Iberian unit of length, roughly comparable to the English yard. Its precise length varied significantly depending on the region and historical period, reflecting local customs and lack of centralized standardization before the metric era.
Commonly cited values include:
- Castilian Vara (Vara de Castilla): Approximately 83.59 centimeters (cm) or 32.91 inches (in). This was arguably the most influential standard in Spain and many of its colonies.
- Portuguese Vara: Typically longer, around 110 cm or 43.3 inches.
- Texas Vara: Legally defined in Texas as exactly 33 1/3 inches (approximately 84.67 cm).
Other regional variations existed throughout Spain, Portugal, Latin America, and other territories under their influence.
Note: The Smoot is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Vara belongs to the imperial/US customary system.
History of the Smoot and Vara
The Smoot unit originated in October 1958 during the pledge activities of the Lambda Chi Alpha fraternity at MIT. Pledges were tasked with measuring the length of the Harvard Bridge, which connects Boston and Cambridge, Massachusetts, over the Charles River.
Instead of using conventional measuring tools, the fraternity members decided to use one of their pledges, Oliver Smoot, as the unit of measure. They repeatedly laid him down end-to-end across the bridge, marking off increments in paint. His companions carried him or helped him move for each new measurement.
The final measurement determined the bridge's length to be 364.4 Smoots "plus or minus one ear". The "ear" indicated the uncertainty of the measurement, adding to the absurdity and humor of the event.
The painted markings on the bridge became a local landmark. They have been maintained and periodically repainted over the decades, often unofficially by members of the fraternity or other MIT affiliates. The Cambridge Police Department traditionally tolerates the markings because, among other reasons, they serve as useful reference points for identifying locations along the bridge.
Interestingly, Oliver R. Smoot later became a prominent figure in standards organizations, serving as Chairman of the American National Standards Institute (ANSI) and President of the International Organization for Standardization (ISO), an ironic twist given his namesake unit's non-standard nature.
The Vara likely originated from Roman units like the virga and became a fundamental measure in Spain and Portugal during the Middle Ages. Its use spread extensively through colonization from the 15th century onwards, becoming the standard for land measurement and trade in vast territories across the Americas (including areas now part of the US like Texas, California, Florida), Africa, and Asia.
Despite attempts to standardize, such as establishing the Vara de Castilla (sometimes associated with Burgos), enforcement across diverse and distant colonies was inconsistent. This led to the development and persistence of numerous local Varas, often differing slightly based on regional decrees or customary usage. For example:
- The Mexican Vara was later standardized at approximately 83.8 cm, very close to the Castilian.
- The Texas Vara was given its specific legal definition (33 1/3 inches) which remains crucial for interpreting historical land grants in the state.
The adoption of the metric system, beginning in the 19th century, gradually led to the official obsolescence of the Vara in most countries. However, its historical importance, particularly in land records, ensures its continued relevance.
Common Uses for smoots and varas
Explore the typical applications for both Smoot (imperial/US) and Vara (imperial/US) to understand their common contexts.
Common Uses for smoots
The Smoot is not used for any official, scientific, or commercial measurements. Its use is primarily cultural and humorous:
- Harvard Bridge Markings: The painted markings on the bridge sidewalk are its most famous application, indicating distance in Smoots from the Boston side. They are a well-known local landmark.
- MIT Culture and Slang: Used humorously within the MIT community and sometimes in the broader Boston area as a quirky local reference.
- Digital Recognition: The unit gained wider recognition when it was included as a unit of measurement in Google Calculator and Google Earth's ruler tool.
- Popular Culture: Occasionally referenced in media or tech circles as an example of a non-standard or humorous unit.
Common Uses for varas
Historically, the Vara was a primary unit for:
- Land Surveying: Measuring property boundaries, town lots, roads, and vast land grants. It is frequently encountered in historical deeds and surveys throughout Latin America and the Southwestern United States.
- Trade and Commerce: Measuring textiles (cloth), rope, lumber, and other goods sold by length.
- Architecture and Construction: Laying out building foundations, measuring walls, and quantifying construction materials.
- Agriculture: Measuring field dimensions or distances for planting.
Its use today is almost entirely historical or related to the interpretation of old documents and land titles.
Frequently Asked Questions
Questions About Smoot (smoot)
How long is a Smoot?
One Smoot is exactly the height of Oliver R. Smoot in 1958:
- 5 feet 7 inches
- 67 inches
- 1.7018 meters
Is the Smoot an official or standardized unit?
No, the Smoot is not an official or standardized unit of measurement in any system (Imperial, US customary, or SI). It is a non-standard, humorous unit originating from a specific event.
Why is the bridge measurement "plus or minus one ear"?
The "plus or minus one ear" (often written as ± εar) reflects the humorous imprecision of the original measurement method using a person. It signifies the margin of error in a whimsical way, possibly referencing the difficulty of the final partial measurement or simply adding to the prank's absurdity.
Are the Smoot markings still on the Harvard Bridge?
Yes, the markings are traditionally repainted periodically (often by Lambda Chi Alpha members) and are considered a fixture of the bridge. During bridge renovations in 2011, the Massachusetts Department of Transportation restored the markings, acknowledging their cultural significance.

No, the Smoot is not an SI unit. It is a non-standard, informal unit. The SI base unit for length is the meter (m).
What did Oliver Smoot think of the unit?
Oliver Smoot generally embraced his namesake unit with good humor throughout his life and career, often participating in events related to it at MIT.
About Vara (vara)
Why does the length of a Vara vary so much?
The variation stems from several factors:
- Long History: The unit was used for centuries before rigorous international standards like the metric system existed.
- Decentralized Standards: Measurement standards were often set locally or regionally (by kingdom, province, or even city) rather than being effectively enforced across entire empires.
- Physical Standards: Early standards were often based on physical rods, which could vary slightly or degrade over time.
- Customary Usage: Local trade practices and customs often solidified specific lengths for the Vara in different areas. While influential standards like the Castilian Vara existed, practical enforcement across vast colonial territories was difficult, allowing regional variations to flourish and persist.
Is the Vara still used today?
Officially, the Vara has been superseded by the metric system in Spain, Portugal, and all Latin American countries. However, it remains highly relevant in specific contexts:
- Historical Land Records: It is essential for interpreting historical land surveys, deeds, and grants, particularly in Texas, California, New Mexico, Florida, and throughout Latin America. Legal property descriptions may still reference original measurements in Varas.
- Historical Research: Understanding the Vara is crucial for historians studying architecture, urban planning, trade, or agriculture in regions formerly under Spanish or Portuguese rule.
- Cultural Context: While not used for practical measurement, the term might appear in historical literature, place names, or cultural discussions. In very rare, localized instances, informal references might persist among older generations.
How long is a Vara?
There is no single universal length. You must consider the specific regional and historical context. Key values include:
- Castilian Vara (Spain): ~83.59 cm / ~32.91 inches
- Portuguese Vara: ~110 cm / ~43.3 inches
- Mexican Vara: ~83.8 cm / ~33.0 inches
- Texas Vara (USA): Exactly 33 1/3 inches / ~84.67 cm
