Land Calculator
Bigha • Gaj • Marla • Plot area
A bigha is not the same size everywhere. In Uttar Pradesh, Bihar and Rajasthan a pucca bigha is 27,225 sq ft; in West Bengal it is 14,400 sq ft; in Madhya Pradesh 12,000. Land Calculator asks which state your land is in once, and then every bigha, biswa, katha and dhur is the size used there.
Type an area once and see it in all 31 units at the same time — bigha, biswa, katha, dhur, gaj, marla, kanal, guntha, cent, decimal, acre, hectare, square feet and more — with your state's own units first. Where a size differs from village to village, the app says so.
Measure a plot from its sides: a rectangle, a triangle, or any four-sided plot from four sides and one diagonal, split into two triangles so the area is exact even when the plot is not a rectangle. In English, हिंदी and বাংলা; works offline, with no account.

What's inside
Every unit, at your state's size
Pick your state once. Bigha, biswa, katha and dhur follow its size, its own units come first (marla and kanal for Punjab and Haryana, guntha for Maharashtra, cent for Kerala), and any unit can be switched to another size — pucca or kachha bigha, rural or Kolkata katha.
Exact plot area
Rectangle from length and width, triangle from three sides, and any four-sided plot from four sides and one diagonal — two exact triangles, never the 'average of opposite sides' shortcut. Sides in feet, metres or gaj; the area in every unit.
Made for daily use
Pin the pairs you convert most (bigha → sq ft, marla → gaj) so they stay on top, reopen any of your last 50 conversions, share a result as text, and choose Indian (1,00,000) or international number grouping.
