Hectare to Dismil (Decimal) Converter

If you own agricultural land or a small residential plot in Bihar, West Bengal, Jharkhand, Assam or Odisha, chances are your land papers mention the area in dismil, also written as decimal. But when the same land shows up in a government survey record, revenue map or a bank loan document, it is usually written in hectares instead. That mismatch between the local unit and the official metric unit is exactly why so many landowners search for a simple hectare to dismil converter before finalising a sale, a mortgage or a partition of family land.

In this guide we will explain the exact formula used to convert hectare to dismil, give you ready to use conversion tables, and answer the specific questions people usually have while working out dismil values from their hectare based land records.

What Is a Hectare?

A hectare is an internationally recognised metric unit of area, equal to 10,000 square metres or approximately 2.471 acres. Because it is defined purely in metric terms, a hectare means the same thing everywhere in the world, whether the land is in Bihar, Punjab or anywhere else. Government departments in India rely on hectares for official land records, agricultural census data and revenue documentation, since it gives a standard, comparable figure regardless of which state the land is located in.

What Is a Dismil (Decimal)?

Dismil, commonly written as decimal in everyday use, is a traditional land measurement unit widely used across eastern and central India, particularly in Bihar, Jharkhand, West Bengal, Assam and Odisha. Unlike bigha or biswa, which change size from state to state, dismil has a fixed and consistent relationship with the acre. One dismil is defined as exactly one hundredth of an acre, which makes it a fairly precise and predictable unit compared to other traditional land measurements used in India.

In practical terms, one dismil works out to approximately 435.6 square feet, or close to 40.47 square metres. Because it is tied directly to the acre rather than to a locally defined bigha, dismil does not vary from district to district the way biswa or bigha does, which makes hectare to dismil conversion much more straightforward and reliable.

Hectare to Dismil Formula

The formula for converting hectare to dismil is simple and consistent across India:

Dismil = Hectare × 247.1

This value comes from the same underlying relationship used to convert hectares into acres. Since 1 hectare equals approximately 2.471 acres, and 1 acre equals exactly 100 dismil, multiplying these two figures gives the standard conversion factor of roughly 247.1 dismil per hectare.

To reverse the calculation and convert dismil back into hectares, use this formula instead:

Hectare = Dismil × 0.004047

Or equivalently, divide the dismil value by 247.1 to get the hectare figure.

How Much Is 1 Hectare in Dismil?

1 hectare is equal to approximately 247.1 dismil. This figure is consistent across nearly all Indian states where dismil is used as a land measurement unit, since dismil is directly linked to the acre rather than to a regionally varying bigha. A few sources round this figure slightly differently, showing values between 247.1 and 247.13 dismil per hectare, but the difference is small enough that it does not meaningfully affect everyday property calculations.

Dismil to Hectare Conversion Table

Dismil (Decimal)	Hectare
1 Dismil	0.004047 Hectare
5 Dismil	0.020235 Hectare
10 Dismil	0.040469 Hectare
25 Dismil	0.101172 Hectare

200 Dismil	0.809372 Hectare

These tables cover the values landowners most commonly need, from small residential plots measured in a handful of dismil to large agricultural holdings recorded in multiple hectares.

How Many Hectares Is a Dismil?

One dismil equals approximately 0.004047 hectare. Since dismil is a much smaller unit compared to a hectare, this number naturally looks tiny in decimal form. As a quick mental shortcut, remember that 100 dismil makes up roughly 0.4047 hectare, and 247 dismil makes up almost exactly 1 hectare.

Is 1 Hectare Equal to 1 Acre?

No, 1 hectare is not equal to 1 acre. A hectare is a metric unit equal to 10,000 square metres, while an acre is an imperial unit equal to 43,560 square feet. 1 hectare works out to approximately 2.471 acres, meaning a hectare is noticeably larger than a single acre. Since 1 acre is fixed at exactly 100 dismil, this same 2.471 acre relationship is what gives us the 247.1 dismil per hectare conversion figure.

How Much Is 1 Acre in Dismil?

1 acre is equal to exactly 100 dismil. This is one of the simplest and most reliable relationships in Indian land measurement, since dismil was specifically designed as a hundredth part of an acre, similar to how a cent works in South Indian states. Because of this fixed relationship, converting between acre and dismil never requires knowing which state or district the land is located in.

Is Dismil the Same as Decimal?

Yes, dismil and decimal refer to exactly the same unit of land measurement. Decimal is simply the more commonly used English spelling, while dismil is the traditional term still found in older land records, especially in Bihar and West Bengal. Both terms are used interchangeably in property documents, sale deeds and government revenue records, and there is no difference in value between the two.

Hectare to Dismil in Bihar

In Bihar, dismil is one of the most widely used units for measuring agricultural and residential land, especially for small and mid sized plots. Since dismil maintains its standard relationship with the acre throughout the state, 1 hectare in Bihar comes to approximately 247.1 dismil, the same figure used across most of eastern India. This consistency makes Bihar land records comparatively easier to convert than states relying on bigha or biswa, where values can change from district to district.

Hectare to Dismil in West Bengal

West Bengal also relies heavily on dismil for everyday property transactions, particularly for smaller urban and semi urban plots. As with Bihar, the conversion factor of roughly 247.1 dismil per hectare applies consistently, since dismil is tied to the fixed acre value rather than to a locally defined bigha. This makes West Bengal one of the more straightforward states when converting land area between hectares and dismil for sale deeds or mutation records.

Why Dismil Is Easier to Convert Than Bigha or Biswa

Unlike bigha and biswa, which are historically defined units that vary significantly from one state to another, and sometimes even between districts within the same state, dismil has a single, nationally consistent definition tied directly to the acre. This is the main reason hectare to dismil conversion does not require choosing a specific state before calculating, unlike hectare to bigha or hectare to biswa conversions where the multiplier changes depending on local revenue practices.

That said, it is still worth keeping a few points in mind before relying on any converted figure for an official transaction.

Always double check the exact conversion factor used, since some sources round it to 247.1 while others use 247.11 or 247.13, leading to very small differences in the final figure.
Confirm the area mentioned in your land record actually refers to dismil and not a similarly named local unit, since a few regions use terms that sound similar but carry a different value.
For large transactions, cross verify the converted hectare or dismil value with your local land registration office before finalising any paperwork.

Frequently Asked Questions

How much is 1 Hectare in Dismil?

1 hectare is equal to approximately 247.1 dismil. This figure remains fairly consistent across India since dismil is derived directly from the acre rather than from a state specific bigha value.

What is the formula to convert Hectare to Dismil?

The formula is Dismil = Hectare × 247.1. To convert in the opposite direction, use Hectare = Dismil × 0.004047, or simply divide the dismil value by 247.1.

How many Hectares is a Dismil?

1 dismil equals approximately 0.004047 hectare. Since dismil is a much smaller unit, this value appears as a small decimal fraction when expressed in hectares.

Is 1 Hectare equal to 1 Acre?

No. 1 hectare equals approximately 2.471 acres, making it noticeably larger than a single acre. This 2.471 ratio is also the basis for the 247.1 dismil per hectare conversion factor.

How much is 1 Acre in Dismil?

1 acre is equal to exactly 100 dismil. This relationship stays fixed everywhere in India, unlike acre to bigha or acre to biswa, which change depending on the state.

Is Dismil the same as Decimal?

Yes, dismil and decimal are the same unit of land measurement, just spelled differently. Older land records commonly use the term dismil, while modern documents often use decimal instead.
