What is a Link (Gunter's) and a Wa?

The Link, specifically Gunter's Link (symbol li), is a unit of length historically used in surveying, particularly within the imperial and U.S. customary systems. It is defined as exactly 1/100th of a Gunter's chain.

One Gunter's link is equivalent to:

  • 0.01 Gunter's chains
  • 7.92 inches (in)
  • 0.66 feet (ft) (exactly 2/3 of a foot)
  • 0.22 yards (yd)
  • 0.04 rods (also called poles or perches)
  • 0.201168 meters (m) (exactly)
  • 20.1168 centimeters (cm)

A Gunter's chain itself measures 66 feet, 22 yards, 4 rods, or 20.1168 meters.

The Wa (วา) is a traditional Thai unit of length. It is legally defined in relation to the metric system as exactly 2 meters.

The Wa serves as a fundamental unit within the traditional Thai system of measurement, particularly for land area. It is roughly equivalent to the distance between a person's outstretched fingertips when their arms are extended horizontally to the sides (similar to a fathom).

Note: The Link (Gunter's) is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Wa belongs to the imperial/US customary system.

History of the Link (Gunter's) and Wa

The link, as part of Gunter's chain, was devised by the English clergyman and mathematician Edmund Gunter around 1620. He introduced a measuring chain that was 66 feet long and divided into 100 links. This system was revolutionary for surveyors because its decimal nature (100 links per chain) simplified calculations, especially for area. Land area could be easily calculated in square chains and then converted to acres, as 10 square chains equal exactly 1 acre. Gunter's chain and its links became the standard tools for land surveying in England and later throughout the British Empire and the United States for centuries.

The Wa has been used in Thailand (formerly Siam) for centuries, likely originating from anthropomorphic measurements like the arm span. It was a practical unit for everyday measurements, construction, and land surveying.

  • Traditional System: The Wa was part of a system that included smaller units like the khuep (span, ~25 cm), sok (cubit, ~50 cm, 1 Wa = 4 Sok), and larger units like the sen (rope, 1 Sen = 20 Wa).
  • Standardization: During the modernization reforms under King Chulalongkorn (Rama V) in the late 19th and early 20th centuries, Thailand began standardizing its weights and measures. The Weights and Measures Act of 1923 formally defined traditional units in terms of the metric system. The Wa was officially set at exactly 2 meters.
  • Metrication: While Thailand officially adopted the metric system as its primary standard, traditional units like the Wa remain legally defined and widely used, especially in specific contexts like land measurement.

Common Uses and Applications: links vs wa

Explore the typical applications for both Link (Gunter's) (imperial/US) and Wa (imperial/US) to understand their common contexts.

Common Uses for links

The Gunter's link is now largely obsolete but was historically significant:

  • Land Surveying: It was the fundamental unit for measuring property boundaries and land parcels in English-speaking countries for over 300 years.
  • Cartography: Used in creating maps and plats based on surveys.
  • Land Records: Measurements in links (and chains) frequently appear in older property deeds, historical surveys, and legal descriptions of land. Understanding the link is crucial for interpreting these documents.
  • Agriculture: The system was tied to the definition of the acre, a common unit of land area.

Its use declined dramatically with the adoption of the metric system and the advent of more precise surveying technologies like steel tapes, theodolites, Electronic Distance Measurement (EDM), and GPS.

When to Use wa

The Wa's most significant modern use is in land measurement, but it historically had broader applications:

  • Land Area: This is the most common contemporary use. Land area in Thailand is almost exclusively measured in Tarang Wa (ตารางวา - Square Wa).
    • 1 Tarang Wa = 4 square meters (2m x 2m)
    • 1 Ngan (งาน) = 100 Tarang Wa (400 sq m)
    • 1 Rai (ไร่) = 4 Ngan = 400 Tarang Wa (1600 sq m) Property deeds, real estate listings, and land surveys invariably use Rai, Ngan, and Tarang Wa.
  • Length Measurement: While meters are now standard for most length measurements (textiles, construction materials), the Wa might still be used informally or in traditional contexts. Historically, it was used for measuring distances, building dimensions, rope lengths, etc.
  • Construction & Architecture: Traditionally used for laying out building plots and determining dimensions in Thai architecture.
  • Cultural Context: Understanding the Wa and its related area units is essential for navigating real estate, agriculture, and historical contexts in Thailand.

Additional Unit Information

About Link (Gunter's) (li)

How long is a Gunter's Link?

One Gunter's Link is equal to:

  • 7.92 inches
  • 0.66 feet (2/3 ft)
  • 0.201168 meters
  • 20.1168 centimeters

How many links are in a Gunter's chain?

There are exactly 100 links in one Gunter's chain.

How long is a Gunter's Chain?

One Gunter's chain is equal to:

  • 100 links
  • 66 feet
  • 22 yards
  • 4 rods (or poles, perches)
  • 1/10th of a furlong
  • 1/80th of a statute mile
  • 20.1168 meters

How does the link relate to the acre?

The link is directly related to the acre through the Gunter's chain. An acre is defined as 10 square chains. Since 1 chain = 100 links:

  • 1 acre = 10 × (100 links)² = 10 × 10,000 square links = 100,000 square links. This decimal relationship greatly simplified area calculations for surveyors using the chain.

Is the link an SI unit?

No, the Gunter's link is not an SI unit. It is part of the traditional imperial and U.S. customary systems. The corresponding SI unit for length is the meter (m).

Is the Gunter's link still used today?

No, the Gunter's link is rarely used in modern surveying practice. Its primary relevance today is in historical contexts, particularly when interpreting old land deeds, surveys, and maps created using Gunter's system. Modern surveying relies on meters or feet, measured with advanced electronic equipment.

Why was it called a 'link'?

It was called a 'link' because Gunter's chain was literally constructed from 100 physical metal links connected by rings. Each link served as a unit of measurement.

About Wa (wa)

How long is a Wa?

A Wa is defined as exactly:

  • 2 meters (m)
  • 200 centimeters (cm)
  • Approximately 6.5617 feet (ft)
  • Approximately 78.74 inches (in)

What are the related traditional Thai length units?

The Wa fits into a system, often based on factors of 2 and 10:

  • Smaller Units:
    • 1 Wa = 4 Sok (ศอก - cubit, ~50 cm)
    • 1 Sok = 2 Khuep (คืบ - span, ~25 cm)
    • 1 Khuep = 12 Nio (นิ้ว - finger breadth, ~2.08 cm, not the English inch)
  • Larger Unit:
    • 1 Sen (เส้น - rope/chain) = 20 Wa (40 meters)
    • 1 Yot (โยชน์ - league) = 400 Sen (16 kilometers)

How is the Wa used for area measurement?

The primary unit for land area is the Tarang Wa (Square Wa):

  • 1 Tarang Wa = 1 Wa × 1 Wa = 2 m × 2 m = 4 square meters Larger area units are based on the Tarang Wa:
  • 1 Ngan = 100 Tarang Wa (400 m²)
  • 1 Rai = 4 Ngan = 400 Tarang Wa (1600 m²)
  • (For reference, 1 Acre ≈ 2.53 Rai, 1 Hectare = 6.25 Rai)

Is the Wa an SI unit?

No, the Wa is not an SI unit. It is a traditional Thai unit, although its legal definition is based on the SI unit, the meter (m).

Is the Wa still used today?

Yes, absolutely. While the metric system is the official standard for science, commerce, and industry, the Wa (especially as Tarang Wa for area) remains the standard unit for land measurement in Thailand. It is legally recognized and used in all official land documents and real estate transactions. Its use for linear measurement is less common but may still occur informally or in traditional settings.
