🏠 Carpet ↔ Built-up ↔ Super Area Converter

RERA mandates carpet area disclosure. Use this to estimate other types.

Usable internal floor
Typically 1.18× carpet
Typically 1.4× carpet
📋 Typical Ratios (varies by builder):
• Carpet : Built-up ≈ 1 : 1.15-1.20 (15-20% added for inner walls)
• Carpet : Super ≈ 1 : 1.30-1.50 (common areas like lobby, stairs, lift well, parking)
• Loading factor = (Super − Carpet) / Carpet × 100. Higher loading = less actual usable space.
