Farmland and large plots in many parts of India are measured in acres, while city plots are in square feet or gaj. Local units such as bigha, guntha and cent vary by state; guntha and cent are included in the unit converter on the home page.
Frequently asked questions
How many sq ft is 1 acre?
Exactly 43,560 square feet.
How many guntha is 1 acre?
One acre is about 40 gunthas (1 guntha ≈ 101.17 m²).
Why is bigha not included?
The size of a bigha differs from state to state (and even within states), so a single conversion would be misleading. Use the local revenue-record value.
