To convert deciares (da) to square kilometers (km²), use the fact that 1 deciare = 10 m² and 1 km² = 1,000,000 m². That means:
Example:
This deciare to square kilometer conversion works for any value. Just multiply by 0.00001 to get km².
A deciare (daa) is a metric unit of area. It equals 10 square meters (m²). People use it for small land plots, garden areas, and farm planning.
A square kilometer (km²) is a metric unit of area used for large areas. It equals 1,000,000 square meters (m²). It’s common for city sizes, regions, and land coverage on maps.
1 deciare equals 0.00001 square kilometers.
In other words: 1 daa = 1 × 10⁻⁵ km².
Multiply the number of deciares by 0.00001.
Formula:
km² = deciares × 0.00001
There are 100,000 deciares in 1 square kilometer.
Formula:
deciares = km² × 100,000
A deciare is 10 m², and a square kilometer is 1,000,000 m².
So you divide 10 by 1,000,000:
10 m² ÷ 1,000,000 m² = 0.00001 km²
Convert in two steps:
Combined, it’s the same as: km² = deciares × 0.00001
No. These are different metric area units:
Use deciares for smaller land areas like yards, gardens, and small fields. Use square kilometers for large areas like towns, counties, and wide land tracts.
Move the decimal point 5 places to the left.
Example:
25,000 daa → 0.25 km²
It depends on the use:
Example:
37 daa = 0.00037 km² (don’t round too early if accuracy matters)
Yes, in some places deciares show up in land listings or farm records. For large properties, km² can be easier to read since the numbers stay smaller.
