Land Size Calculator

Land Size Calculator – Instantly Convert Ropani, Aana, Bigha, Kattha & More

Ever found yourself stuck trying to figure out how many square feet are in a Ropani? Or maybe someone mentioned a piece of land measured in Bigha, and you weren’t sure how big that actually is. You’re not alone; land measurement in Nepal can be confusing. That’s exactly why this calculator exists.

Whether you’re buying, selling, or just trying to understand your property better, this tool helps you quickly convert between traditional land units like Ropani, Aana, Paisa, Daam, Bigha, Kattha, and Dhur; right into square meters and square feet.

In the hills, people mostly use Ropani-Aana-Paisa-Daam. But in the Terai, it’s all about Bigha-Kattha-Dhur. Different systems, different values, same confusion. This calculator clears it up. Simple. Fast. No guesswork. Just plug in what you know; and get what you need.

Understanding Land Measurement Units in Nepal

If you’ve ever had to measure or deal with land in Nepal, you already know it’s not as straightforward as it seems. Different places use different systems, and that can quickly get confusing. Let’s break it down in a way that actually makes sense.

Hilly Region (Ropani-Aana System)

If you’re from Kathmandu, Pokhara, or most hill areas, you’ve probably heard land measured in Ropani, Aana, Paisa, or Daam. Here’s how it works:

• 1 Ropani = 16 Aana
• 1 Aana = 4 Paisa
• 1 Paisa = 4 Daam
  So, 1 Ropani = 16 Aana = 64 Paisa = 256 Daam

When converted:

• 1 Ropani = 508.72 square meters = 5476 square feet

Here’s a quick cheat sheet:

Unit	Square Meters	Square Feet
1 Ropani	508.72	5476
1 Aana	31.80	342.25
1 Paisa	7.95	85.56
1 Daam	1.99	21.39

Simple enough once you see it laid out like that.

Terai Region (Bigha-Kattha System)

Now, if you’re from the Terai—places like Biratnagar, Janakpur, or Nepalgunj—then you’re dealing with a different system altogether.

• 1 Bigha = 20 Kattha
• 1 Kattha = 20 Dhur
  So, 1 Bigha = 20 Kattha = 400 Dhur

Converted into modern units:

• 1 Bigha = 6772.63 square meters = 72,900 square feet
• 1 Kattha = 338.63 square meters = 3,645 square feet
• 1 Dhur = 16.93 square meters = 182.25 square feet

Here’s your reference table:

Unit	Square Meters	Square Feet
1 Bigha	6772.63	72900
1 Kattha	338.63	3645
1 Dhur	16.93	182.25

Pro Tip

If you’re in Kathmandu, Lalitpur, Bhaktapur, Pokhara, or other hill areas, land is usually measured in Ropani-Aana-Paisa-Daam.
But if you’re from Biratnagar, Janakpur, Birgunj, Dhangadhi, or anywhere in the Terai, it’s all about Bigha-Kattha-Dhur.

Knowing which system your area uses can save you from a lot of confusion—and possibly even a costly mistake.
