1. Understanding Area Units

Metric System: Based on square meters (m²). 10,000 m² = 1 hectare, 1,000,000 m² = 1 km².
Imperial System: Based on square feet. 144 in² = 1 ft², 9 ft² = 1 yd², 43,560 ft² = 1 acre.
Key Conversion: 1 m² = 10.764 ft², 1 acre = 4,047 m², 1 hectare = 2.471 acres.

2. Common Area Conversions

SqM to SqFt: Multiply by 10.764 (e.g., 100 m² = 1,076.4 ft²)
SqFt to SqM: Divide by 10.764 (e.g., 500 ft² = 46.45 m²)
Acres to Hectares: Multiply by 0.4047 (e.g., 5 acres = 2.02 ha)
Hectares to Acres: Multiply by 2.471 (e.g., 2 ha = 4.94 acres)

3. Practical Applications

• Real Estate: Property listings, apartment/house sizes, plot measurements
• Construction: Floor area, roofing calculations, material estimates
• Landscaping: Lawn area, garden beds, paving, irrigation planning
• Agriculture: Farm land, crop field measurements, land allocation
• Interior Design: Room sizes, flooring, carpet, tile calculations

4. Area Calculation Basics

Square/Rectangle: Area = Length × Width
Triangle: Area = (Base × Height) ÷ 2
Circle: Area = π × radius²
Remember to use consistent units when calculating area. If length is in meters and width is in feet, convert one to match the other before multiplying.

5. Indian Regional Units (Land Measurement)

Decimal/Decimel: Common in West Bengal and Bihar. 1 Decimal = 435.6 sqft = 40.47 m²
Cent: Used in South India (Kerala, Tamil Nadu). 1 Cent = 435.6 sqft = 40.47 m² = 1/100th of an acre
Bigha: North India unit (varies by region). Standard Bigha = 27,225 sqft = 2,529 m² ≈ 0.625 acres
Katha/Cottah: West Bengal & Bihar. 1 Katha = 1,361.25 sqft = 126.5 m² = 1/20th of a Bigha
Guntha/Gunta: Maharashtra, Karnataka. 1 Guntha = 1,089 sqft = 101.17 m² = 1/40th of an acre
Ground: South India (Andhra Pradesh, Telangana, Karnataka). 1 Ground = 2,400 sqft = 203.3 m²

6. Common Indian Land Conversions

Decimal to SqFt: Multiply by 435.6 (e.g., 10 Decimal = 4,356 sqft)
Cent to SqM: Multiply by 40.47 (e.g., 5 Cent = 202.3 m²)
Bigha to Acre: Multiply by 0.625 (e.g., 4 Bigha = 2.5 acres)
Guntha to SqFt: Multiply by 1,089 (e.g., 5 Guntha = 5,445 sqft)
Ground to SqFt: Multiply by 2,400 (e.g., 2 Ground = 4,800 sqft)
Katha to SqM: Multiply by 126.5 (e.g., 3 Katha = 379.5 m²)
Note: Regional variations exist - always verify local standards for property transactions.

7. Area Conversion Tips

• For quick estimates: 1 m² ≈ 10.75 ft² (roughly 11 ft²)
• Real estate: 100 m² ≈ 1,076 ft² (about 1,100 ft² for quick math)
• Large land: 1 hectare ≈ 2.5 acres
• Sports fields: Football field ≈ 0.7 hectare or 1.75 acres
• Indian property: 1 Bigha ≈ 27,000 sqft, 1 Guntha ≈ 1,089 sqft, 1 Ground ≈ 2,400 sqft
• Always verify area units in international property transactions
• Use hectares for large agricultural plots, acres for smaller farms
