Most common land measurement units in Thailand
These units are commonly used for agricultural and land measurement purposes in Thailand:
- 1 Rai = 4 Ngan
- 1 Rai = 400 Tarang Wah (Square Wah)
- 1 Rai = 1,600 Square Meters
- 1 Ngan= 100 Tarang Wah
- 1 Ngan = 400 Square Meters
- 1 Tarang Wah = 4 Square Meters (2 meters x 2 meters = 4 square meters)
- 1 Wah = 2 Meters
In Thailand, the commonly used unit of land measurement is “Tarang Wah.” When written, it’s typically represented using a three-part number, starting with the largest unit and progressing to the smallest. So, when writing land measurements, you generally start with the number of “Rai,” followed by the number of “Ngan,” and finally the number of “Tarang Wah.”
For example, if you have a land size of 2 Rai, 3 Ngan, and 50 Tarang Wah, it would be written as “2-3-50” (Rai-Ngan-Tarang Wah).
Thai real estate measurement units, such as Rai, Ngan, and Tarang Wah, originated from Thailand’s traditional agricultural practices. This stems from the fact that the appraised land prices issued by the Treasury Department will show the appraised land price in units of (Baht per Tarang Wah). The specific tasks within a Rai can vary depending on the type of work and the specific industry. For example, in agriculture, the amount of work in 1 Rai might include planting, harvesting, and maintenance, which could require several workers. However, if referring to the amount of output that can be generated on 1 Rai, it is depend on the particluar business or industry.
Do you know? What is Rai? How many square wah are there in 1 Rai?
“Rai” is the largest unit of land measurement commonly used in Thailand. It is often used to measure land, agricultural plots, and residential areas. The word “rai” is also widely used in neighboring countries such as Laos and Cambodia, with a similar meaning. A “rai” can be converted to other units of land area as follows:
- 1 rai = 400 square wa
- 1 rai = 4 ngan
- 1 rai = 1600 square meters
How many square wah in 1 rai?
1 Rai is equal to 400 square wah. If you want to convert land of 1 Rai to square wah, you can use the formula:
(Formula: Square Wah = Rai x 400)
Therefore, if you have land of (X Rai), the conversion would be: Square Wah = X * 400
For example, if you have land of 2 Rai, the conversion would be: Area in square wah = 2 Rai x 400 = 800 square wah.
Therefore, 2 Rai of land is equal to 800 square wah.
Conversely, if you want to convert units from square wah to Rai, you must use this calculation formula:
(Formula: Rai = Square Wah ÷ 400)
So, if you have land of (X square wah), the conversion is: Rai = X / 400
For example, if you have land of 800 square wah, the conversion is: Number of Rai = 800 square wah ÷ 400 = 2 Rai
Therefore, land of 800 square wah is equal to 2 Rai.
How many ngan in 1 rai?
1 Rai is equal to 4 Ngan. If you want to convert the land unit 1 Rai into Ngan, you can use the following formula:
(Formula: Ngan = Rai x 4)
Therefore, if you have land (X Rai), the conversion would be: Ngan = X * 4
For example, if you have 2 Rai of land, the conversion would be: Number of Ngan = 2 Rai x 4 = 8 Ngan.
Therefore, 2 Rai of land is equal to 8 Ngan.
Conversely, if you want to convert the unit from Ngan to Rai, you must use this calculation formula:
(Formula: Rai = Ngan ÷ 4)
So, if you have land (X Ngan), the conversion would be: Rai = X / 4
For example, if you have 8 Ngan of land, the conversion is: Number of Rai = 8 Ngan ÷ 4 = 2 Rai.
Therefore, 2 Rai of land is equal to 8 Ngan. (This last sentence is a repeat of the earlier example and is likely a typo in the original Thai). It is technically correct, though.
Rai to Square Meters?
1 Rai is equal to 1,600 square meters. If you want to convert a land area of 1 Rai to square meters, you need to use this calculation formula:
(Formula: Square meters = Rai x 1,600)
Therefore, if you have land (X Rai), the conversion would be: Square meters = X * 1,600
For example, if you have 2 Rai of land, the conversion would be: Area in square meters = 2 Rai x 1,600 = 3,200 square meters.
Therefore, 2 Rai of land is equal to 3,200 square meters.
Conversely, if you want to convert from square meters to Rai, you need to use this calculation formula:
(Formula: Rai = Square meters ÷ 1,600)
Therefore, if you have land (X square meters), the conversion would be: Rai = X / 1,600
For example, if you have 3,200 square meters of land, the conversion would be: Number of Rai = 3,200 ÷ 1,600 = 2 Rai.
Therefore, 3,200 square meters of land is equal to 2 Rai.
What is a tarang wa? How many square meters are in 1 tarang wa?
“Tarahng Wah” (ตารางวา) is the smallest unit of land measurement, from among the three units of land measurement commonly used in Thailand and other Southeast Asian countries. It is used to measure land area, and one Tarahng Wah is equal to 4 square meters (2 meters squared). The word “Wah” (วา) comes from the Thai word “Wah” (วา), which is a traditional Thai unit of length equal to 2 meters. Therefore, a “Tarahng Wah” means a square with sides of 2 meters each.
In Thailand, land and property are often measured in Tarahng Wah, especially in real estate transactions. Land appraisal prices issued by the Treasury Department use the unit (Baht per Tarahng Wah). It is a convenient unit of measurement for smaller plots of land, such as residential properties or small farms used for business.
1 tarang wa = ? sq m
1 Tarang Wa (square wa) is equal to 2 meters (squared) or is equal to 4 square meters. You need to use this calculation formula:
(Formula: Square meters = Tarang Wa x 4)
1 Wa is equal to 2 meters (squared), which is (1 Tarang Wa) multiplied by (2 meters x 2 meters) = 4 square meters.
Therefore, the answer is that 1 Tarang Wa is equal to 4 square meters.
For example, if you have land of 3 Tarang Wa, the conversion would be: Area in square meters = 3 Tarang Wa multiplied by 4 = 12 square meters.
Therefore, 3 Tarang Wa of land is equal to 12 square meters.
1 square meter = ? square wa
Conversely, if you want to convert units from square meters to Talang Wah (ตารางวา), you need to use this calculation formula:
(Formula: Talang Wah = Square meters ÷ 4)
Wherein 1 square meter is equal to 0.25 Talang Wah (meaning that 1 square meter is one-fourth, of 1 Talang Wa, as in, 4 square meters divided by 4 equals 1 Talang Wa)
For example, if you have 12 square meters of land, the conversion would be: Area in Talang Wah = 12 square meters ÷ 4 = 3 Talang Wah.
Therefore, 12 square meters of land is equal to 3 Talang Wah.
What is a “Ngan”? How many square wah in 1 Ngan?
Ngan” (งาน) is a unit of land measurement smaller than a “rai” (ไร่). It falls between the rai and the square wa (tarang wa) in size (rai-ngan-tarang wa). Of these three land measurement units, “ngan” is typically used for measuring smaller plots of land, such as residential areas or agricultural fields. One rai is equal to four ngan.
1 Ngan Equals How Many Square Wah?
1 Ngan is equal to 100 square wah. If you want to convert an area of 1 Ngan to square wah, you can use the formula:
(Formula: Square Wah = Ngan * 100)
Therefore, if you have land of (X Ngan), the conversion would be: Square Wah = X * 100
For example, if you have 2 Ngan of land, the conversion would be: Area in square wah = 2 Ngan * 100 = 200 square wah.
So, 2 Ngan of land is equal to 200 square wah.
Conversely, if you want to convert from square wah to Ngan, you must use this calculation formula:
(Formula: Ngan = Square Wah ÷ 100)
Therefore, if you have (X square wah) of land, the conversion would be: Ngan = X / 100
For Example, if you have land of 200 Square Wah. The Conversion would be: Number of Ngan = 200 / 100 = 2 Ngan.
So, Land of 200 Square Wah is equal to 2 Ngan.
How many square meters in 1 Ngan?
1 Ngan is equal to 400 square wa. If you want to convert 1 Ngan of land into square meters, you can use the following formula:
(Formula: Square meters = Ngan * 400)
Therefore, if you have land (X Ngan), the conversion would be: Square meters = X * 400
For example, if you have 2 Ngan of land, the conversion would be: Area in square meters = 2 Ngan * 400 = 800 square meters.
So, 2 Ngan of land is equal to 800 square meters.
Conversely, if you want to convert from square meters to Ngan, you need to use this calculation formula:
(Formula: Ngan = Square meters / 400)
Therefore, if you have Land (X square meters), the conversion is: Ngan = X divided by 400
For example, if you have land that is 800 square meters, the conversion is: Number of ngan = 800 / 400 = 2 ngan.
Therefore, 800 square meters of land is equal to 2 Ngan.
