In this article, Mytour.vn will share with you the concept, methods to convert hectares to m2, square km and vice versa. With the content in this article, surely you can also convert the area of fields, hills, mountains,... that you need to buy, sell or be assigned to survey, calculate the area,...
1 Ha equals how many m2, square km
1. Convert 1 ha to m2, square km
Hectare is an international unit of measurement, commonly used in surveying to measure agricultural and forestry land areas. (To learn more about hectare, you can refer directly to the Wiki through this link.)
- 1 ha (hecta) = 10,000 m2.
- One hectare equals how many square kilometers: 1 ha (hecta) = 0.01 km2 (1/100 km2)
- 1100 ha equals how many m2: 1100 ha = 1100 x 10,000 = 11,000,000 (eleven million m2)
The results above are due to predefined area conversion formulas. Specifically, the universally adopted formula for area conversion worldwide is:
2. Standard units for measuring area worldwide
Current area measurement units include: m2, km2, hm2, dam2, ha. Specifically, the conversion formulas for basic area measurement units are as follows:
- 1 km2 = 100 ha.
- 1 km2 = 100 hm2.
- 1 hm2 = 100 dam2.
- 1 dam2 = 100 m2.
- 1 km2 = 1,000,000 m2 (equivalent to one million square meters).
3. Another way to convert hectares
In addition to hectares, local residents in the Northern, Central, and Southern regions of Vietnam also have their own conventions for defining and converting land area. Specifically:
- For provinces in the Northern region
- 1 km2 = 100 ha.
- 1 km2 = 100 hm2.
- 1 hm2 = 100 dam2.
- 1 dam2 = 100 m2.
- 1 km2 = 1,000,000 m2 (equivalent to one million square meters). Convention: 1 sào in the Northern region = 360m2, 1 mẫu = 10 sào
To convert hectare to Northern Vietnam units, follow this calculation:
+ 1 hectare equals how many Northern Vietnam units: 1 ha = 10,000/ 360 = 27.78 Northern Vietnam units
+ 1 ha equals how many plots: 1 ha = 10,000/(360 x 10)=2.778 Northern Vietnam plots
- For Central Vietnam provinces
Convention: 1 Central Vietnam unit = 500m2, 1 plot = 10 units
Thus, 1 ha of land will be converted to units, plots of Central Vietnam as follows:
+ 1 ha = 10,000/500 = 20 units Central Vietnam
+ 1ha = 10,000/(500 x 2) = 2 plots Central Vietnam
- For Southern Vietnam provinces
Convention: 1 unit = 1000m2, 1 plot = 10 units
+ According to this convention, 1 ha will be equivalent to 10 units Southern Vietnam and 1 plot Southern Vietnam (formula calculation similar to above)
