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

Square Kilometre vs Hectare: which is bigger?
A square kilometre is the larger unit: one square kilometre equals 100 hectares. Put another way, you need 100 hectares 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 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.

Tips for converting Square Kilometre to Hectare
- To go from square kilometre to hectare, multiply by 100; to go back, divide by 100 (or multiply by 0.01).
- For a quick mental estimate, remember that 1 square kilometre ≈ 100 hectare, so 10 square kilometre ≈ 1,000 hectare.
- 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 Hectare converter
Type a number into the Square Kilometre field and the equivalent in Hectare 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 Hectare field to convert the other way (hectare 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 = 100 ha), 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-hectare 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 hectare are in 1 square kilometre?
- 1 square kilometre = 100 hectare (ha). To convert any number of square kilometre to hectare, multiply by 100.
- How do I convert square kilometre to hectare?
- Multiply the number of square kilometre by 100. For example, 10 square kilometre = 10 × 100 = 1,000 hectare, and 25 square kilometre = 2,500 hectare.
- How many square kilometre are in 1 hectare?
- 1 hectare = 0.01 square kilometre. So to convert hectare back to square kilometre, multiply by 0.01.
- What is the formula to convert square kilometre to hectare?
- hectare = square kilometre × 100. The reverse formula is square kilometre = hectare × 0.01.
- How much is 100 square kilometre in hectare?
- 100 square kilometre = 10,000 hectare. (And 1000 square kilometre = 100,000 hectare.)
- Which is bigger, a square kilometre or a hectare?
- A square kilometre is larger: 1 square kilometre = 100 hectare.
- Is this square kilometre to hectare converter accurate?
- Yes — every value is computed from the exact 100 ha per km² factor (not rounded look-up tables), and the factors are re-verified automatically on every update.
- Can I convert hectare to square kilometre too?
- Yes. The converter works both ways — enter a value in either field. 1 hectare = 0.01 square kilometre.
