How to read an RTC extent
The RTC writes extent as acres-guntas: 3-20 means 3 acres 20 guntas. In acres that is 3 + 20 ÷ 40 = 3.5 acres; in square feet, multiply total guntas by 1,089: (3 × 40 + 20) × 1,089 = 152,460 sq ft. Kharab shown on the RTC is not part of the cultivable extent.
Price per gunta, per acre and per square foot
Because 1 acre = 40 guntas, ₹1,00,000 per gunta equals ₹40,00,000 per acre. ₹1,000 per square foot equals ₹10,89,000 per gunta (1,089 × ₹1,000).
