Quick guide
Understanding area units
Area conversion becomes important whenever land is being compared, sold, recorded, or discussed across different measurement systems. Metric units like square meters and hectares are widely used, but South Asia also relies on local units like bigha, katha, and decimal.
This converter helps when you need a common reference point across those systems so you can compare property listings or documents more confidently.
Common area conversions
- 1 acre = 4,046.86 sq m = about 3 bigha in some local references
- 1 bigha (BD) = 20 katha = 33 decimal
- 1 decimal = 435.6 sq ft = 40.47 sq m
- 1 hectare = 10,000 sq m = 2.471 acres
- 1 katha (BD) = about 720 sq ft
Practical example
If a plot is listed in decimal but your buyer is more comfortable thinking in square feet, a quick area conversion makes the property easier to understand. That is especially useful when comparing land offers from different regions.
Frequently Asked Questions
What is a bigha?
A bigha is a traditional land unit used in South Asia, but its exact size changes by region. That is why area conversion for land deals should always use the local standard.
How many katha are in a bigha?
In Bangladesh, one bigha is commonly treated as 20 katha. Some regions in India use different ratios, so the local context matters.
Why is area conversion important for land work?
Area conversion is crucial when you are comparing land listings, checking deeds, or reviewing land records that mix metric and traditional units.

Why conversion errors usually happen
Most conversion mistakes happen because the wrong unit, base, or direction was selected at the start. A tiny mismatch can turn into an expensive or frustrating error when you are dealing with money, dimensions, recipes, file formats, or travel planning.
The safest habit is to confirm the input unit first, then sanity-check whether the output feels reasonable before you copy it into a purchase, form, spreadsheet, or message.

This is helpful when you are moving between systems, recipes, documents, academic work, or country-specific conventions.
