It depends on the state. This is the most confusing conversion in Indian land measurement:

How do I convert square feet to square meters?
Multiply by 0.0929 (or divide by 10.764)
| Sq Ft | Sq Meters | |-------|----------| | 500 | 46.45 | | 1000 | 92.90 | | 1200 | 111.48 | | 1500 | 139.35 | | 2000 | 185.81 | | 2500 | 232.26 |
What is the difference between carpet area, built-up area, and super area?
| Type | Includes | Typical % of Super Area | |------|----------|------------------------| | Carpet area | Usable floor space only | 70-75% | | Built-up area | Carpet + walls + balconies | 80-85% | | Super built-up area | Built-up + common areas (lobby, stairs) | 100% |
Example: A 1500 sq ft super area apartment:
- Carpet area ≈ 1,050–1,125 sq ft
- Built-up area ≈ 1,200–1,275 sq ft
The Trench Truth: RERA (Real Estate Regulatory Authority) now mandates that developers quote prices based on carpet area, not super area. This eliminates the "loading factor" ambiguity. If a listing still quotes per sq ft of super area, convert to carpet area before comparing with other properties.
