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 Decimal? History, origin and usage

The decimal, also called satak or dismil, is a unit equal to one-hundredth of an acre that arose from British-era revenue surveys, which divided the acre into 100 equal parts. In Bengali-speaking areas it is satak, from shotangsho meaning 'hundredth part', the same idea that gives the unit its English name.

It is widely used across eastern India, especially Bihar, West Bengal, Odisha and Jharkhand, as well as in Bangladesh, for residential plots, agricultural land and government land records. Property advertisements and news reports in these regions still quote land in decimals.

One decimal is identical in size to one cent, both being one-hundredth of an acre (about 435.6 square feet). One hundred decimals therefore make exactly one acre.

How to use this Square Kilometre to Decimal converter

Type a number into the Square Kilometre field and the equivalent in Decimal 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 Decimal field to convert the other way (decimal 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 = 24,710.54 decimal), 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-decimal conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
