The converter at the top does this instantly and both ways; the sections below give the formula, worked examples, a full conversion chart and answers to the most common square kilometre-to-decare questions.
How to convert Square Kilometre to Decare
To convert square kilometre to decare, multiply the number of square kilometre by the conversion factor 1,000, because 1 km² = 1,000daa. The conversion is linear, so the same factor works for any value — whole numbers, decimals or fractions. For the reverse direction, 1 daa = 0.001km², so you divide by 1,000 (or multiply by 0.001) to turn decare back into square kilometre.
daa = km² × 1,000 ·
km² = daa × 0.001
- Write down the value you want to convert, in square kilometre.
- Multiply it by 1,000.
- The result is the same area/length/quantity expressed in decare.

Square Kilometre vs Decare: which is bigger?
A square kilometre is the larger unit: one square kilometre equals 1,000 decares. Put another way, you need 1,000 decares to make a single square kilometre.
What is a Square Kilometre? History, origin and usage
The square kilometre is an SI-based unit of area equal to a square one kilometre on each side. It became the natural large-area metric unit once the kilometre was adopted for long distances.
It is used for the areas of cities, districts, countries, lakes and other large regions on maps and in geography and statistics. National and regional land areas are almost universally reported in square kilometres.
One square kilometre equals 100 hectares or 1,000,000 square metres, and is about 0.386 square mile. For scale, the entire Vatican City covers only about half a square kilometre.
What is a Decare? History, origin and usage
The decare is a metric land unit of 1,000 square metres, equal to 10 ares or one-tenth of a hectare. It corresponds to the modern metric dunam, whose name comes from the Ottoman Turkish donum (from donmek, 'to turn'), originally the area a team of oxen could plough in a day.
The decare and its dunam equivalent are used in Norway, Turkey and parts of the Balkans, while the metric dunam of 1,000 square metres adopted in 1928 is standard in Israel and Palestine. It is a convenient mid-size unit between the are and the hectare.
One decare equals one metric dunam, exactly 1,000 square metres, and ten decares make one hectare. The Ottoman dunam was a regional cousin of the English acre and the Greek stremma, all rooted in a day's ploughing.

Tips for converting Square Kilometre to Decare
- To go from square kilometre to decare, multiply by 1,000; to go back, divide by 1,000 (or multiply by 0.001).
- For a quick mental estimate, remember that 1 square kilometre ≈ 1,000 decare, so 10 square kilometre ≈ 10,000 decare.
- The converter above keeps full precision; the tables round for readability, so use the tool for exact figures.
- Both fields update live as you type — change either side to convert in that direction.
How to use this Square Kilometre to Decare converter
Type a number into the Square Kilometre field and the equivalent in Decare appears instantly — there is no “convert” button to press and nothing is sent to a server, so it works offline once the page has loaded and is safe for any data. You can also type into the Decare field to convert the other way (decare to square kilometre). Use the swap control to flip the two units, and copy the result with a single click. Because the calculation runs in your browser with full floating-point precision, the converter is more exact than the rounded figures shown in the reference chart above — use the chart for quick look-ups and the tool for precise work.
Accuracy and method
Every figure on this page — the formula, the worked examples, the conversion chart and the “convert to other units” tables — is computed from a single verified conversion factor (1 km² = 1,000daa), never copied from a hand-typed lookup table that could drift. That factor is derived from each unit’s definition in terms of a common base unit, and an automated check re-verifies all of the site’s factors on every update, so the numbers here stay correct over time. This matters for square kilometre-to-decare conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
Indian land units can vary by state and local custom. This converter uses the most widely accepted standard value; always confirm against your local revenue records (patwari / tehsil) for legal transactions.
