When exploring land matters, units like Mẫu, Sào, and Hecta are commonly used, especially for large plots. In this article, Mytour guides you through converting mẫu, sào, and hecta to square meters.

What is a Land Mẫu? How many sào in 1 Mẫu?

In the North, Central, and South regions of Vietnam, the area of mẫu varies. Each region has its own dimensions due to the lack of international standardization for the mẫu unit. It's a folk unit used by Vietnamese farmers for calculating the area of agricultural land, fish ponds, etc.
Note: There is no universal conversion method for Mẫu; each locality has its own calculation when converting Mẫu to square meters (m2).
However, when transforming Mẫu into sào, all three regions—North, Central, and South—share a common formula, specifically as follows:
- 1 Mẫu = 10 sào (one mẫu equals ten sào)
- 1 Mẫu = 10 công (one mẫu equals ten công)
2. Northern Region – How much is 1 Mẫu in square meters, sào, Ha

1. How many square meters is 1 Mẫu in the Northern region?
In the Northern region, agricultural development flourishes with fertile lands enriched by sediment from mighty rivers all year round. The people in the North are closely connected to lush agricultural lands, fields of abundant rice, and beautiful white grains...
Before converting from Mẫu to m2, it's essential to convert Mẫu to the unit of sào, as these are commonly used units for measuring agricultural land.
- 1 Mẫu = 10 Sào
- 1 Sào = 360 m2 (according to the conversion in the Northern region)
1. In the North, 1 Mẫu of land equals 3,600 square meters (One Mẫu in the North equals three thousand six hundred square meters).
2. How many hectares is 1 Mẫu in the Northern region?
When converting 1 Mẫu of land to square meters, it's easy to convert them to Hectares because m2 and Ha are common measurement units worldwide under the SI standard. To convert from m2 to Ha, you simply divide by 10,000.
- 1 Mẫu Northern Region = 3,600 m2 = 0.36 Ha (One Mẫu Northern Region equals three thousand six hundred square meters and equals zero point three six hectares).
3. Central Region – How Much is 1 Mẫu in Square Meters, Sào, Ha
1. What is the equivalent of 1 Mẫu in square meters in the Central Region?
In the Central region of Vietnam, the unit of Mẫu is commonly used for agricultural areas, cultivated land, and fish ponds...
Before converting from Mẫu to m2, it's necessary to convert Mẫu to the unit of sào, as these are commonly used units for measuring agricultural land.
- 1 Mẫu is equivalent to 10 Sào
- 1 Sào = 500 m2 (according to the conversion in the Central region)
Therefore, 1 Mẫu of land in the Central region equals 5,000 m2 (One Mẫu of land in the Central region equals five thousand square meters).
How Many Hectares is 1 Mẫu in the Central Region
When converting 1 Mẫu of land to square meters, it becomes easy to convert them to Hectares because m2 and Ha are common measurement units worldwide under the SI standard. To convert from m2 to Ha, you simply divide by 10,000.
- 1 Mẫu Northern Region = 5,000 m2 = 0.5 Ha (One Mẫu Northern Region equals five thousand square meters and equals zero point five hectares).
4. Southern Region – How Much is 1 Mẫu in Square Meters, Sào, Ha
How Many Square Meters is 1 Mẫu in the Southern Region
The Southern region of Vietnam, particularly famous for vast fields along the Mekong Delta, is a major rice-producing region for the country. Before converting from Mẫu to m2, it's necessary to convert Mẫu to the unit of sào, as these are commonly used units for measuring agricultural land.
- 1 Mẫu = 10 Sào
- 1 Sào = 1,000 m2 (as per the conversion in the Southern region)
Before converting from Mẫu to m2, it's necessary to convert Mẫu to the unit of sào, as these are commonly used units for measuring agricultural land.
- 1 Mẫu = 10 Sào
- 1 Sào = 1,000 m2 (as per the conversion in the Southern region)
Therefore, 1 Mẫu of land in the Central region equals 10,000 m2 (One Mẫu of land in the Central region equals ten thousand square meters).
How Many Hectares is 1 Mẫu in the Southern Region
When converting 1 Mẫu of land to square meters, it becomes easy to convert them to Hectares because m2 and Ha are common measurement units worldwide under the SI standard. To convert from m2 to Ha, you simply divide by 10,000.
- 1 Mẫu Southern Region = 10,000 m2 = 1 Ha (One Mẫu Southern Region equals ten thousand square meters and equals one hectare).
5. Is Mẫu Still Commonly Used for Land Measurement?

As society develops, people are gradually changing to adhere to community standards, international standards, and similar measurement units. In reality, Mẫu has been used as a land measurement unit since the country regained peace. Our farmers used Mẫu to measure allocated fields. However, due to the lack of uniformity, Mẫu does not have its own standard. It is measured differently in each place and is no longer suitable. Therefore, people now use hectares to replace Mẫu in modern life because it is an internationally recognized standard unit.
Mẫu for land is currently widely used by older individuals who have spent a significant amount of time engaged in cultivation and farming. The younger generation is shifting away from using Mẫu as a land measurement unit and gradually adopting international units such as Hectares, square kilometers, etc.
In this article, Mytour has guided you on how to convert Mẫu to square meters, field sào, hectares. Wishing you a joyful day!
