Why convert area units?

Area measures 2D space – the size of a surface or region. Different units are used in different contexts: square meters (m²) for rooms and small properties in metric countries, square feet (ft²) for US real estate and floor plans, acres for farmland and large properties, hectares for European farms and forest areas, square kilometers (km²) for cities and regions, square miles (mi²) for US states and large areas. India uses unique units like ‘gaj’ (square yard), ‘bigha’ (varies by state, 0.25-3 acres), and ‘gunta’ (40 guntas = 1 acre, southern India). Converting between units is essential for: real estate transactions (buying property in different countries), comparing farm sizes, urban planning, home renovation projects, and understanding international news mentioning areas.

Area conversion factors

All conversions via square meter (m²) base:

• 1 m² = 10,000 cm² = 0.000001 km²
• 1 cm² = 0.0001 m²
• 1 km² = 1,000,000 m² = 100 hectares
• 1 in² = 6.4516 cm² = 0.000645 m²
• 1 ft² = 0.0929 m² = 144 in²
• 1 yd² = 0.836 m² = 9 ft²
• 1 mi² = 2,589,988 m² = ~640 acres
• 1 are (a) = 100 m² (small unit, rarely used today)
• 1 hectare (ha) = 10,000 m² = 100 ares
• 1 acre = 4,046.86 m² = ~40.4% of hectare

Quick references:

• 1 m² ≈ 10.76 ft² (multiply m² by 10.76 to get ft²)
• 1 ft² ≈ 0.0929 m² (small – a basketball)
• 1 acre ≈ 4047 m² ≈ 43,560 ft² (about 0.4 hectare)
• 1 hectare = 10,000 m² = 2.47 acres
• 1 km² ≈ 247 acres ≈ 100 hectares

Examples

• 2 BHK apartment, 800 ft²: 74.3 m², 0.0184 acre, 0.00929 hectare
• 3 BHK villa, 1500 ft²: 139 m², 0.0344 acre
• Indian property 250 gaj: ~209 m² = ~2,250 ft²
• Farm 5 acres: 20,234 m² = 217,800 ft² = 2.02 hectares
• Football pitch (soccer field, FIFA standard): 7,140 m²: 76,800 ft², 1.76 acres, 0.714 hectare
• Manhattan island 87 km²: 21,494 acres, 8,700 hectares, 33.6 mi²
• Lake Tahoe ~497 km²: 122,800 acres, 192 mi²
• India total area 3,287,263 km²: 1,269,219 mi², 812.3 million acres

Tips & best practices

• For Indian real estate, 1 sq ft is universal. For farmland, acre or hectare. For very small areas, sq cm or sq m. For state/country areas, km² or mi²
• Carpet area (Indian flat measurement) vs built-up area: built-up is 15-20% larger (includes walls)
• Super built-up area (Indian usage) includes common areas like staircase, lobby – 20-30% larger than carpet area
• 1 acre ≈ size of one US football field (with end zones); 1 hectare ≈ size of two football fields
• For irregular shapes, divide into rectangles/triangles and add areas – or use a digital area measurement tool
• Forest/farmland surveys typically use hectares (metric world) or acres (US, UK historical)
• Property listings: check unit carefully. ‘1500 sq’ could mean ft² or m² – always clarify

Limitations & notes

Indian state-specific units (bigha varies by state – 0.27 acre in West Bengal, 1.62 acres in UP, etc.) aren’t included – convert via standard units. Doesn’t include ‘gunta’ (40 gunta = 1 acre, southern India) or ‘kanal’ (variants of 5-8 marla, Punjab/Pakistan). For exact local-unit conversion, consult local real estate norms.

Frequently Asked Questions

What is the conversion from sq ft to sq m?

Divide sq ft by 10.76 (or multiply by 0.0929). Example: 1500 sq ft = 1500 / 10.76 = 139.4 sq m. Conversely, 100 sq m = 100 x 10.76 = 1076 sq ft.

How big is an acre?

1 acre = 4,047 m² = 43,560 ft². About the size of a US football field including end zones, or about 1.6 cricket pitches (a cricket pitch is 22 yards x 10 feet wide). One acre supports a small house with garden, or 2-3 cricket fields, or about 200 typical urban apartments.

How is ‘bigha’ different from acre?

Bigha is an Indian/South Asian unit that varies by state. West Bengal: 1 bigha = 1,338 m² (0.33 acre). Uttar Pradesh: 1 bigha = 2,508 m² (0.62 acre). Some states: 1 bigha = 4,047 m² (1 acre). Always confirm which bigha is meant when buying property!

What’s the difference between carpet area and built-up area?

Carpet area: actual usable floor space inside walls. Built-up area: carpet area + walls + balconies (typically 10-15% more). Super built-up area: built-up + common areas (lobbies, staircase, lifts) – typically 20-30% more than carpet. Apartments are sold by super built-up but you LIVE in carpet area. RERA (real estate regulation, India) mandates carpet area disclosure to prevent confusion.

How big is a typical Indian home in different units?

1 BHK ~500-700 sq ft = 46-65 m². 2 BHK ~800-1100 sq ft = 74-102 m². 3 BHK ~1200-2000 sq ft = 111-186 m². Villas ~2500+ sq ft = 232+ m². For comparison, US average home is ~2,400 sq ft = 223 m².

Why is the area unit so different in different industries?

Historical and convenience reasons. Real estate: traditional units (ft², m², acre). Agriculture: large units (acre, hectare). Science: SI units (m², km²). US: imperial throughout. Each industry standardized when it was developed.

What’s a ‘gaj’ in Indian property?

1 gaj = 1 square yard = 9 sq ft = 0.836 m². Common in north Indian property listings. ‘Plot of 200 gaj’ = 1800 sq ft = 167 m². Originally from Mughal-era measurement, still widely used.
