Convert Hectare to Decare
1 hectare = 10 decare (daa). For example, 10 hectare = 100 decare and 100 hectare = 1,000 decare. Type any value below to convert hectare to decare both ways — it runs entirely in your browser.
Quick answer: Hectare to Decare
1 Hectare = 10 Decare (ha → daa). To convert hectare to decare, multiply by 10. To convert decare to hectare, multiply by 0.1. 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 hectare-to-decare questions.
How to convert Hectare to Decare
To convert hectare to decare, multiply the number of hectare by the conversion factor 10, because 1 ha = 10 daa. The conversion is linear, so the same factor works for any value — whole numbers, decimals or fractions. For the reverse direction, 1 daa = 0.1 ha, so you divide by 10 (or multiply by 0.1) to turn decare back into hectare.
daa = ha × 10 ·
ha = daa × 0.1
- Write down the value you want to convert, in hectare.
- Multiply it by 10.
- The result is the same area/length/quantity expressed in decare.

Hectare vs Decare: which is bigger?
A hectare is the larger unit: one hectare equals 10 decares. Put another way, you need 10 decares to make a single hectare.
What is a Hectare? History, origin and usage
The hectare belongs to the metric system created during the French Revolution; the law of 18 Germinal, Year III (1795) defined the are as 100 square metres for measuring land. The hectare is 100 ares, its name combining the Greek hecto- (hundred) with the are.
It is the legal unit for land area across the European Union, Australia, New Zealand, Canada and much of the world, used in agriculture, forestry, planning and land management. In India it appears in official agricultural statistics and land records alongside the acre.
One hectare is 10,000 square metres, about 2.47 acres, and 100 hectares make one square kilometre. It is close in size to an international rugby pitch, which makes it a handy mental yardstick.
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 Hectare to Decare
- To go from hectare to decare, multiply by 10; to go back, divide by 10 (or multiply by 0.1).
- For a quick mental estimate, remember that 1 hectare ≈ 10 decare, so 10 hectare ≈ 100 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 Hectare to Decare converter
Type a number into the Hectare 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 hectare). 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 ha = 10 daa), 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 hectare-to-decare conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
Sources
- BIPM — The International System of Units (SI Brochure) — the defining document for the SI, published by the International Bureau of Weights and Measures. It fixes the base unit that this conversion resolves to, which is why the factor here can be exact rather than approximate.
- NIST — Definitions of the SI base units — the US National Institute of Standards and Technology reference for the SI base units, used here as an independent cross-check on the base-unit definition.
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.
Frequently asked questions
- How many decare are in 1 hectare?
- 1 hectare = 10 decare (daa). To convert any number of hectare to decare, multiply by 10.
- How do I convert hectare to decare?
- Multiply the number of hectare by 10. For example, 10 hectare = 10 × 10 = 100 decare, and 25 hectare = 250 decare.
- How many hectare are in 1 decare?
- 1 decare = 0.1 hectare. So to convert decare back to hectare, multiply by 0.1.
- What is the formula to convert hectare to decare?
- decare = hectare × 10. The reverse formula is hectare = decare × 0.1.
- How much is 100 hectare in decare?
- 100 hectare = 1,000 decare. (And 1000 hectare = 10,000 decare.)
- Which is bigger, a hectare or a decare?
- A hectare is larger: 1 hectare = 10 decare.
- Is this hectare to decare converter accurate?
- Yes — every value is computed from the exact 10 daa per ha factor (not rounded look-up tables), and the factors are re-verified automatically on every update.
- Can I convert decare to hectare too?
- Yes. The converter works both ways — enter a value in either field. 1 decare = 0.1 hectare.
