Conversion Factors & Indian Standards Explained
All conversions use normalized base units (SI standards and statutory Indian revenue land standards): 1. Area & Indian Land Measurement: • 1 Acre = 43,560 sq ft = 4,046.86 m² = 40 Guntha = 1.6 Standard Bigha (North India = 27,225 sq ft). • 1 Guntha = 1,089 sq ft = 121 sq yards = 33 ft × 33 ft. • 1 Gaj (Square Yard) = 9 sq ft = 0.8361 m². • 1 Ground (Tamil Nadu) = 2,400 sq ft. • 1 Cent (South India) = 435.6 sq ft (1/100 Acre). 2. Weight & Indian Gold Standards: • 1 Tola = 11.6638 grams (standard statutory weight of one silver rupee coin in British India). • 1 Pavan / Sovereign = 8 grams (standard gold jewellery unit in South India). • 1 Quintal = 100 kg | 1 Metric Tonne = 1,000 kg. 3. Indian vs International Numbering System: • 1 Lakh = 100 Thousand = 10⁵ (1,00,000) • 1 Million = 10 Lakh = 10⁶ (1,000,000) • 1 Crore = 100 Lakh = 10 Million = 10⁷ (1,00,00,000) • 1 Billion = 100 Crore = 1 Arab = 10⁹ (1,000,000,000)
Example 1: Converting Land Area (2.5 Acres to Guntha)
Category: Area | From: Acre | To: Guntha | Value: 2.5
1 Acre = 40 Guntha 2.5 × 40 = 100 Guntha
2.5 Acres = 100 Guntha (1,08,900 sq ft)
Example 2: Converting Gold Weight (5 Tola to Grams)
Category: Weight | From: Tola | To: Gram | Value: 5
1 Tola = 11.6638 grams 5 × 11.6638 = 58.319 grams
5 Tola = 58.319 Grams (approx 7.29 Pavan)
Example 3: Financial Figures (15 Crore to Millions)
Category: Indian Numbering | From: Crore | To: Million | Value: 15
1 Crore = 10 Million 15 × 10 = 150 Million
15 Crore = 150 Million ($/₹)
Measurement Guidelines
- ✓Bigha sizes vary by Indian state (e.g. Pucca Bigha vs Kacha Bigha); our calculator uses standard North Indian revenue Bigha (27,225 sq ft).
- ✓For plot purchases in India, property sizes are frequently quoted in Gaj (Square Yards) or Square Feet (1 Gaj = 9 sq ft).
- ✓For gold valuation in India, hallmark rates are quoted per 10 grams or per 1 Tola (11.664 g).
- ✓Use the Indian Numbering converter when comparing foreign startup funding (in millions/billions) to Indian Rupees (in Crores).
Common Regional Errors
- ✗Confusing Square Yards (Gaj) with Square Feet (1 Gaj is 9 times larger than 1 sq ft).
- ✗Assuming 1 Billion is 10 Crore (1 Billion = 100 Crore or 1 Arab).
- ✗Assuming Bigha is identical in all Indian states without verifying local patwari revenue records.
- ✗Mixing up US Gallons (3.785 L) with UK Imperial Gallons (4.546 L).
