Question 3

What are the most common area unit conversions?

Accepted Answer

1 acre = 4,047 m² ≈ 0.405 hectares ≈ 43,560 sq ft. 1 hectare = 10,000 m² = 2.471 acres. 1 sq mile = 640 acres = 2.59 km². 1 sq km = 100 hectares = 247.1 acres. 1 sq ft = 0.0929 m². 1 sq m = 10.764 sq ft. In India: 1 bigha varies by state (1,337–3,108 m²). 1 cent = 1/100 acre = 40.47 m² (South India). 1 guntha = 101.17 m² (Maharashtra).

Question 4

What apartment sizes are typical in India?

Accepted Answer

Standard sizes: 1 BHK = 400–650 sq ft (37–60 m²). 2 BHK = 650–1,100 sq ft (60–102 m²). 3 BHK = 1,000–1,600 sq ft (93–149 m²). RERA mandates disclosure of carpet area. 'Carpet area' (usable floor) is typically 70–75% of the marketed 'super built-up area' (which includes walls, common areas, and amenities). Always compare on carpet-area basis when evaluating properties.

Question 5

What is the difference between carpet area, built-up area, and super built-up area?

Accepted Answer

Carpet area: actual usable floor space inside the apartment. Built-up area: carpet area + walls + balcony — typically 10–15% more than carpet area. Super built-up area: built-up area + proportional share of common spaces (lobby, staircase, gym, amenities) — typically 25–30% more than carpet area. RERA requires builders to sell on carpet-area basis, but marketing often uses super built-up area to make apartments appear larger.
