Convert Hectare to Square Kilometre
1 hectare = 0.01 square kilometre (km²). For example, 10 hectare = 0.1 square kilometre and 100 hectare = 1 square kilometre. Type any value below to convert hectare to square kilometre both ways — it runs entirely in your browser.
Quick answer: Hectare to Square Kilometre
1 Hectare = 0.01 Square Kilometre (ha → km²). To convert hectare to square kilometre, multiply by 0.01. To convert square kilometre to hectare, multiply by 100. 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-square kilometre questions.
How to convert Hectare to Square Kilometre
To convert hectare to square kilometre, multiply the number of hectare by the conversion factor 0.01, because 1 ha = 0.01 km². The conversion is linear, so the same factor works for any value — whole numbers, decimals or fractions. For the reverse direction, 1 km² = 100 ha, so you divide by 0.01 (or multiply by 100) to turn square kilometre back into hectare.
km² = ha × 0.01 ·
ha = km² × 100
- Write down the value you want to convert, in hectare.
- Multiply it by 0.01.
- The result is the same area/length/quantity expressed in square kilometre.

Hectare vs Square Kilometre: 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 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 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 Hectare to Square Kilometre
- To go from hectare to square kilometre, multiply by 0.01; to go back, divide by 0.01 (or multiply by 100).
- For a quick mental estimate, remember that 1 hectare ≈ 0.01 square kilometre, so 10 hectare ≈ 0.1 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 Hectare to Square Kilometre converter
Type a number into the Hectare 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 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 = 0.01 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 hectare-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 hectare?
- 1 hectare = 0.01 square kilometre (km²). To convert any number of hectare to square kilometre, multiply by 0.01.
- How do I convert hectare to square kilometre?
- Multiply the number of hectare by 0.01. For example, 10 hectare = 10 × 0.01 = 0.1 square kilometre, and 25 hectare = 0.25 square kilometre.
- How many hectare are in 1 square kilometre?
- 1 square kilometre = 100 hectare. So to convert square kilometre back to hectare, multiply by 100.
- What is the formula to convert hectare to square kilometre?
- square kilometre = hectare × 0.01. The reverse formula is hectare = square kilometre × 100.
- How much is 100 hectare in square kilometre?
- 100 hectare = 1 square kilometre. (And 1000 hectare = 10 square kilometre.)
- Which is bigger, a hectare or a square kilometre?
- A square kilometre is larger: 1 square kilometre = 100 hectare.
- Is this hectare to square kilometre converter accurate?
- Yes — every value is computed from the exact 0.01 km² per ha factor (not rounded look-up tables), and the factors are re-verified automatically on every update.
- Can I convert square kilometre to hectare too?
- Yes. The converter works both ways — enter a value in either field. 1 square kilometre = 100 hectare.
