What is a deciare (da)?
A deciare (da) is a metric unit of area. It equals 10 square meters (m²). You may see it used for land size, garden plots, and small lots.
How many square inches are in 1 deciare?
1 deciare equals 15,500.031 square inches (in²).
What is the formula to convert deciares to square inches?
Use this conversion:
- Square inches = deciares × 15,500.031
This works because 1 deciare is 10 m², and 1 m² equals about 1,550.0031 in².
How do you convert deciares to square inches step by step?
- Start with the area in deciares.
- Multiply by 15,500.031.
- The result is in square inches (in²).
Example:
2 da × 15,500.031 = 31,000.062 in²
Why does the deciare to square inches number look so large?
Square inches are much smaller than square meters. Since 1 deciare equals 10 m², the same area becomes a big number when measured in inches.
Is a deciare the same as an are?
No. They are related, but not the same:
- 1 are (a) = 100 m²
- 1 deciare (da) = 10 m²
So, 1 are = 10 deciares.
How many square inches are in 0.1 deciare?
0.1 deciare equals 1,550.0031 in².
Calculation:
0.1 × 15,500.031 = 1,550.0031
How many square inches are in 5 deciares?

- Material estimates (sheet goods, turf, tile)
- Comparing plot sizes using U.S. units
How do I round deciares to square inches?
Rounding depends on your use:
- For general estimates, round to the nearest whole in².
- For layouts or build plans, keep at least 1 decimal place.
- For high-accuracy work, keep more digits and round at the end.
Does this conversion change based on location?
No. A deciare and a square inch have fixed sizes. The conversion is the same everywhere.
Can I convert square inches back to deciares?
Yes. Use the inverse formula:
- Deciares = square inches ÷ 15,500.031
Example:
31,000.062 in² ÷ 15,500.031 = 2 da
