The Finger (sometimes finger's breadth, though this can be confusingly similar to the 'digit') is an archaic English unit of length. Its definition was inconsistent, leading to significant ambiguity. Two primary definitions existed:
-
As 1/8th of a yard: This was a common definition, equating the finger to:
- 4.5 inches (in)
- 1/2 of a quarter-yard (or "quarter")
- 0.1143 meters (m)
- 11.43 centimeters (cm)
-
As 1/16th of a yard: This definition made the finger identical to another unit called the nail, equating it to:
- 2.25 inches (in)
- 0.05715 meters (m)
- 5.715 centimeters (cm)
The term likely originated from anthropomorphic measurement but became tied to fractions of the standard yard, particularly in the context of measuring cloth. It is distinct from, and generally longer than, the unit called a digit (typically ~0.75 inches).
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 Finger 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 Finger and Wa
The finger was used historically in England, primarily from the medieval period into the early modern era. Its main application was in the measurement of cloth, alongside other specialized units like the nail (often 2.25 inches) and the ell (often 45 inches).
The existence of multiple definitions (4.5 inches vs. 2.25 inches) highlights the lack of strict standardization for many older units. The 2.25-inch finger was identical to the nail, suggesting the terms might have been used interchangeably in some contexts or that one definition arose from confusion with the other.
Compared to more fundamental units like the inch, foot, yard, or even the digit and palm, the "finger" as a distinct unit (especially the 4.5-inch version) appears less frequently in historical records. Its usage declined significantly with the standardization of the Imperial system (which favored inches and yards) and the later adoption of the metric system. It is now entirely obsolete.
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: fingers vs wa
Explore the typical applications for both Finger (imperial/US) and Wa (imperial/US) to understand their common contexts.
Common Uses for fingers
The finger is obsolete and has no modern practical application. Its relevance is primarily historical:
- Historical Cloth Trade: Measurements in "fingers" might be encountered in older English documents, inventories, or tailor's records related to textiles. Understanding its potential ambiguity (4.5 vs 2.25 inches) is crucial.
- Understanding Historical Units: Studying the finger helps illustrate the complexity and variability of pre-standardized measurement systems and the specific units used in the textile industry.
- Rare & Obsolete: It was never as widespread or consistently defined as units like the inch, foot, or yard.
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 Finger (finger)
How long is a Finger?
The length of a finger was not consistently defined. The two most common historical definitions in England were:
- 4.5 inches (11.43 cm), equal to 1/8th of a yard.
- 2.25 inches (5.715 cm), equal to 1/16th of a yard (and identical to the unit called a 'nail'). Context is essential when encountering this unit in historical texts.
Is a Finger the same as a Digit?
No. Although both terms relate to the human finger, they represented different historical units of length.
- The Digit (or fingerbreadth) was typically much shorter, around 0.75 inches (approx. 1.9 cm), representing the width of a finger.
- The Finger was significantly longer, either 4.5 inches or 2.25 inches, likely derived as a fraction of a yard rather than directly from finger anatomy in later usage.
What is the relationship between a Finger and a Nail?
The unit called a Nail was commonly defined as 1/16th of a yard (2.25 inches). Therefore:
- One definition of the Finger (2.25 inches) was identical to the Nail.
- The other common definition of the Finger (4.5 inches) was twice the length of a Nail.
Is the Finger an SI unit?
No, the finger is not an SI unit. It is an archaic, non-standardized unit primarily used historically in England. The SI base unit for length is the meter (m).
Is the Finger still used?
No, the finger as a unit of length is completely obsolete and is not used in any modern standard, scientific, or commercial measurements. Its relevance is purely historical.
Where does the name 'Finger' come from?
The name undoubtedly originates from the human finger. However, while the digit unit directly related to finger width, the 'Finger' unit (especially the 4.5-inch version) seems to have become a conventional term for a specific fraction (1/8th or 1/16th) of a yard, particularly in cloth measurement, losing its direct anatomical connection.
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.
