Frequently Asked Questions

About Bigha and Square Millimeter

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 Millimeter (mm²)

The square millimeter is one millionth of a square meter, used in precision engineering, wire cross-section ratings, and microscopy.

Electrical engineers use mm² to specify cable conductor cross-sections — a 2.5 mm² cable is standard for household circuits in many countries.

Interesting fact: A human hair cross-section is roughly 0.005 mm², and the eye of a sewing needle is about 1 mm².
