Convert Are to Square Kilometre
1 are = 0.0001 square kilometre (km²). For example, 10 are = 0.001 square kilometre and 100 are = 0.01 square kilometre. Type any value below to convert are to square kilometre both ways — it runs entirely in your browser.
Quick answer: Are to Square Kilometre
1 Are = 0.0001 Square Kilometre (are → km²). To convert are to square kilometre, multiply by 0.0001. To convert square kilometre to are, multiply by 10,000. 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 are-to-square kilometre questions.
How to convert Are to Square Kilometre
To convert are to square kilometre, multiply the number of are by the conversion factor 0.0001, because 1 are = 0.0001 km². The conversion is linear, so the same factor works for any value — whole numbers, decimals or fractions. For the reverse direction, 1 km² = 10,000 are, so you divide by 0.0001 (or multiply by 10,000) to turn square kilometre back into are.
km² = are × 0.0001 ·
are = km² × 10,000
- Write down the value you want to convert, in are.
- Multiply it by 0.0001.
- The result is the same area/length/quantity expressed in square kilometre.

Are vs Square Kilometre: 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 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.
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.

Tips for converting Are to Square Kilometre
- To go from are to square kilometre, multiply by 0.0001; to go back, divide by 0.0001 (or multiply by 10,000).
- For a quick mental estimate, remember that 1 are ≈ 0.0001 square kilometre, so 10 are ≈ 0.001 square kilometre.
- 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 Are to Square Kilometre converter
Type a number into the Are field and the equivalent in Square Kilometre 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 Square Kilometre field to convert the other way (square kilometre to are). 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 are = 0.0001 km²), 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 are-to-square kilometre 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 square kilometre are in 1 are?
- 1 are = 0.0001 square kilometre (km²). To convert any number of are to square kilometre, multiply by 0.0001.
- How do I convert are to square kilometre?
- Multiply the number of are by 0.0001. For example, 10 are = 10 × 0.0001 = 0.001 square kilometre, and 25 are = 0.0025 square kilometre.
- How many are are in 1 square kilometre?
- 1 square kilometre = 10,000 are. So to convert square kilometre back to are, multiply by 10,000.
- What is the formula to convert are to square kilometre?
- square kilometre = are × 0.0001. The reverse formula is are = square kilometre × 10,000.
- How much is 100 are in square kilometre?
- 100 are = 0.01 square kilometre. (And 1000 are = 0.1 square kilometre.)
- Which is bigger, a are or a square kilometre?
- A square kilometre is larger: 1 square kilometre = 10,000 are.
- Is this are to square kilometre converter accurate?
- Yes — every value is computed from the exact 0.0001 km² per are factor (not rounded look-up tables), and the factors are re-verified automatically on every update.
- Can I convert square kilometre to are too?
- Yes. The converter works both ways — enter a value in either field. 1 square kilometre = 10,000 are.
