Frequently Asked Questions

About Bigha and Square Kilometer

Bigha (bigha)

The bigha is a traditional South Asian unit of land area whose size varies significantly by region. In West Bengal, 1 bigha = 1,600 m²; in Uttar Pradesh, 1 bigha ≈ 2,529 m²; in Rajasthan, it can be larger.

Bigha is widely used across India, Nepal, and Bangladesh for agricultural land measurement in rural property transactions and government land records.

Interesting fact: The bigha is not standardized — its size varies from 843 m² (in Himachal Pradesh) to 3,025 m² (in some parts of Rajasthan), making local context essential.

Square Kilometer (km²)

The square kilometer is equal to one million square meters, used for measuring large geographic areas such as countries, forests, lakes, and urban regions.

It became the standard measure for national territories and natural features as cartography evolved in the 19th and 20th centuries alongside the metric system.

Interesting fact: The world's smallest country, Vatican City, covers just 0.44 km². Russia, the largest, spans about 17.1 million km².
