Land Unit Converter

• Every unit at once

  Square feet, acre, hectare, gaj, guntha, kanal, bigha, biswa, katha and the rest — type once and read your land in all of them together. Tap a result to copy it, or share the whole conversion.

• Region-aware conversions

  A Bigha in Uttar Pradesh is not a Bigha in Rajasthan, West Bengal, Bihar or Punjab — and the same is true of Biswa and Katha. Pick your state and the maths follows local reality.

• Instant, as you type

  Results update on every keystroke. There is no Calculate button to hunt for and no result screen to navigate to.

• See the plot you are measuring

  Enter the sides and the plot is drawn to scale as you type, with the corners lettered so you can see which measurement is which side. Rectangles, triangles and irregular plots up to eight corners. If the sides cannot form a real shape it says which one to change, instead of quietly showing a wrong number.

• Priced the way it is quoted

  Put a rate against an area — per square foot, per bigha, per acre, whatever the seller said — and read the total back in lakh and crore.

• English, Hindi and Bengali

  The whole app in all three, unit names and explanations included. The older Bengali units are handled properly — gonda, kora, kranti and til, the ones that still turn up in old record-of-rights entries.

• Know your land

  Every unit comes with a plain explainer — where it is used and how its size shifts by region — so you understand the number instead of just reading it. Search it by whichever name you know: gajam finds gaj, satak finds decimal, khata finds katha.

• Works with no signal

  Conversion is entirely offline, which matters when you are standing on the plot rather than sitting at a desk.

• Light and dark

  A calm, modern interface in both themes, readable in an office or in direct sun.

• 01

  Two listings quote the plot in different units

  Put both into the same unit and find out whether you are actually comparing the same amount of land, or being shown a bigger number.

• 02

  You’re standing on the land right now

  Everything is calculated on your phone, so it works in a field with no signal — which is usually where you need it.

• 03

  The unit means something different where you are

  A Bigha in Uttar Pradesh is not a Bigha in Rajasthan or West Bengal. Pick your state and the maths follows the local value, not an average.

• 04

  You’re not sure what the unit even is

  Each one comes with a plain explanation of where it is used and how much it varies, so the number on the document makes sense.

• Indian land measurement units, and what each one is worth

  Bigha, katha, guntha, gaj, kanal, marla and the rest — what each unit means, how many square feet it is, and which ones change size depending on your state.

• How big is a bigha?

  A bigha has no single size. It is 27,225 square feet as a standard pucca bigha, 27,000 in Uttar Pradesh and about 12,000 in Madhya Pradesh — the state matters.
