Quick answer: Square Kilometre to Are
1 Square Kilometre = 10,000 Are (km² → are). To convert square kilometre to are, multiply by 10,000. To convert are to square kilometre, multiply by 0.0001. 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-are questions.
How to convert Square Kilometre to Are
To convert square kilometre to are, multiply the number of square kilometre by the conversion factor 10,000, because 1 km² = 10,000 are. The conversion is linear, so the same factor works for any value — whole numbers, decimals or fractions. For the reverse direction, 1 are = 0.0001 km², so you divide by 10,000 (or multiply by 0.0001) to turn are back into square kilometre.
are = km² × 10,000 ·
km² = are × 0.0001
- Write down the value you want to convert, in square kilometre.
- Multiply it by 10,000.
- The result is the same area/length/quantity expressed in are.

Square Kilometre vs Are: which is bigger?
A square kilometre is the larger unit: one square kilometre equals 10,000 ares. Put another way, you need 10,000 ares 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 Are? History, origin and usage
The are is the original metric unit of land area, established by the French Revolutionary metric law of 1795 as 100 square metres. Its name comes from the Latin area, and it gave rise to the much more widely used hectare (100 ares).
Today the are itself is rarely used in everyday measurement, having been largely displaced by the square metre and the hectare. It survives mainly in a few European cadastral contexts and as the building block from which the hectare is defined.
One are is a square of 10 metres by 10 metres, and 100 ares make one hectare. It is one of the few metric units whose name survives chiefly inside a larger derived unit.

Tips for converting Square Kilometre to Are
- To go from square kilometre to are, multiply by 10,000; to go back, divide by 10,000 (or multiply by 0.0001).
- For a quick mental estimate, remember that 1 square kilometre ≈ 10,000 are, so 10 square kilometre ≈ 100,000 are.
- 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 Are converter
Type a number into the Square Kilometre field and the equivalent in Are 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 Are field to convert the other way (are 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 = 10,000 are), 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-are 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 are are in 1 square kilometre?
- 1 square kilometre = 10,000 are (are). To convert any number of square kilometre to are, multiply by 10,000.
- How do I convert square kilometre to are?
- Multiply the number of square kilometre by 10,000. For example, 10 square kilometre = 10 × 10,000 = 100,000 are, and 25 square kilometre = 250,000 are.
- How many square kilometre are in 1 are?
- 1 are = 0.0001 square kilometre. So to convert are back to square kilometre, multiply by 0.0001.
- What is the formula to convert square kilometre to are?
- are = square kilometre × 10,000. The reverse formula is square kilometre = are × 0.0001.
- How much is 100 square kilometre in are?
- 100 square kilometre = 1,000,000 are. (And 1000 square kilometre = 10,000,000 are.)
- Which is bigger, a square kilometre or a are?
- A square kilometre is larger: 1 square kilometre = 10,000 are.
- Is this square kilometre to are converter accurate?
- Yes — every value is computed from the exact 10,000 are per km² factor (not rounded look-up tables), and the factors are re-verified automatically on every update.
- Can I convert are to square kilometre too?
- Yes. The converter works both ways — enter a value in either field. 1 are = 0.0001 square kilometre.
