Decimal vs Square Metre: which is bigger?
A decimal is the larger unit: one decimal equals 40.46856 square metres. Put another way, you need 40.46856 square metres to make a single decimal.
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.
What is a Square Metre? History, origin and usage
The square metre is the coherent SI derived unit of area, defined simply as the area of a square one metre on each side. It descends directly from the metre, which was introduced with the metric system in Revolutionary France in the 1790s.
It is the standard area unit worldwide for floor space, land, materials and scientific work, and is the base from which units like the hectare and square kilometre are built. Almost every country except a few uses the square metre for building and property area.
One square metre is about 10.76 square feet, and 10,000 square metres make one hectare. Its symbol, m squared, is the same in every language because it is a pure SI unit.

Tips for converting Decimal to Square Metre
- To go from decimal to square metre, multiply by 40.46856; to go back, divide by 40.46856 (or multiply by 0.02471054).
- For a quick mental estimate, remember that 1 decimal ≈ 40.46856 square metre, so 10 decimal ≈ 404.6856 square metre.
- 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 Decimal to Square Metre converter
Type a number into the Decimal field and the equivalent in Square Metre 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 Metre field to convert the other way (square metre to decimal). 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 decimal = 40.46856 m²), 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 decimal-to-square metre conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
