Indian land measurement units and their values
Land in India is still bought and sold in a mix of old local units and modern ones. Property listings in cities use square feet, revenue records in villages use bigha or guntha, and government schemes often quote hectares. Some of these units have one fixed value everywhere. Others change from state to state, and sometimes between districts in the same state.
The fixed units are easy. These values are exact and the converter uses them as they are:
| Unit | Equal to | Where you will see it |
|---|---|---|
| 1 acre | 43,560 sq ft or 4,046.86 sq m | All over India |
| 1 hectare | 10,000 sq m or about 2.471 acres | Government and agricultural records |
| 1 gaj (square yard) | 9 sq ft or 0.8361 sq m | Plots in Delhi NCR, UP, Punjab, Rajasthan |
| 1 cent | 1/100 acre, which is 435.6 sq ft | Kerala, Tamil Nadu, Karnataka, Andhra Pradesh |
| 1 guntha | 1,089 sq ft (40 guntha make 1 acre) | Maharashtra, Karnataka, Gujarat, Telangana |
| 1 kanal | 1/8 acre, which is 5,445 sq ft | Punjab, Haryana, Himachal, Jammu and Kashmir |
| 1 marla | 272.25 sq ft (20 marla make 1 kanal) | Punjab, Haryana; some municipal areas use 225 sq ft |
| 1 ground | 2,400 sq ft | Chennai and other parts of Tamil Nadu |
Bigha, biswa and katha: why the number depends on your state
Bigha has never had one national value. It grew out of local custom, so a bigha in Assam is roughly half the size of a bigha in Uttar Pradesh. The converter lets you pick a region and uses the values that are most widely documented for that state. All of them should be read as approximate.
| Region | 1 bigha is about | Smaller unit used |
|---|---|---|
| Uttar Pradesh | 27,000 sq ft | 20 biswa = 1 bigha |
| Rajasthan (pucca bigha) | 27,225 sq ft | 20 biswa = 1 bigha |
| Gujarat (vigha) | 17,424 sq ft (16 guntha) | Guntha |
| West Bengal | 14,400 sq ft | 20 katha = 1 bigha (720 sq ft each) |
| Assam | 14,400 sq ft | 5 katha = 1 bigha (2,880 sq ft each) |
| Himachal Pradesh | 8,712 sq ft | 20 biswa = 1 bigha |
States like Bihar, Jharkhand, Madhya Pradesh, Uttarakhand and Punjab also use bigha, but local values differ so much that we have left them out rather than give you a figure that may be wrong for your village. Rajasthan also has a smaller kachha bigha in some areas.
Before you pay an advance or sign a sale deed, check the area in your official land record: khatauni in Uttar Pradesh, jamabandi in Rajasthan and Punjab, 7/12 extract in Maharashtra, patta or chitta in Tamil Nadu. Most states now show these online. If the record is in bigha, ask the patwari or tehsil office what value applies locally, and get the area in square metres or hectares written into the agreement. Use this converter to understand a figure, not to settle a dispute.
Tola, ser and quintal for weight
A tola is 11.6638 grams. It was fixed in British India as 180 grains, and it is still how many families talk about gold. Jewellers today mostly price gold per 10 grams, so a "one tola chain" is a little heavier than a 10-gram one. If you are comparing a family estimate with a bill, convert tola to grams here first.
The ser (or seer) is older and less reliable. The standard British Indian ser was 80 tola, about 933 grams, and that is the value the converter uses. Many regions had their own ser, and in everyday speech people often use "ek ser" to mean one kilo. Treat any ser conversion as a rough guide.
A quintal is exactly 100 kg. Minimum support prices for wheat, paddy and other crops are announced per quintal, so a farmer selling 35 quintals is selling 3,500 kg, or 3.5 tonnes.
Data storage: why your 1 TB drive shows 931 GB
Storage makers use decimal units, where 1 kilobyte is 1,000 bytes and 1 gigabyte is 1,000,000,000 bytes. Windows measures the same disk in binary units, where each step is 1,024 rather than 1,000, but still labels the result "GB". So a 1 TB hard disk holds 1,000,000,000,000 bytes, which Windows shows as about 931 GB. Nothing is missing.
To avoid this confusion, the converter lists both sets separately. KB, MB, GB and TB are decimal. KiB, MiB, GiB and TiB (kibibyte, mebibyte and so on) are binary. Pick the pair that matches what you are comparing.
Internet speed is another trap. Broadband plans in India are sold in megabits per second (Mbps), but downloads show megabytes per second (MB/s). There are 8 bits in a byte, so a 100 Mbps connection tops out at about 12.5 MB/s. Choose Megabit in the From box and Megabyte in the To box to check your own plan.
Everyday conversions people search for
- Height: 1 foot is 30.48 cm and 1 inch is 2.54 cm, so 5 feet 6 inches is 167.64 cm.
- Body temperature: 98.6 °F is 37 °C. A fever of 100.4 °F is 38 °C.
- Speed: 100 km/h is about 62 mph. 1 knot is 1.852 km/h.
- Cooking: one US cup is about 237 ml. Measuring cup sets sold in India are often the 250 ml metric cup, so check which one your recipe means.

Results show up to ten significant digits and use Indian digit grouping, so a large number appears as 12,34,567. Very large or very small values switch to scientific notation so they stay readable. The copy button copies the plain number without commas.
Frequently asked questions
How many square feet are there in 1 bigha?
It depends on the state. Commonly used values are about 27,000 sq ft in Uttar Pradesh, 17,424 sq ft in Gujarat, 14,400 sq ft in West Bengal and Assam, and 8,712 sq ft in Himachal Pradesh. Always confirm with your local land record or tehsil office.
How many gaj make one bigha?
Divide the bigha's square feet by 9. In Uttar Pradesh that is about 3,000 gaj, and for a Rajasthan pucca bigha it is 3,025 gaj. In West Bengal and Assam it is 1,600 gaj.
How many grams is one tola of gold?
One tola is 11.6638 grams. Ten tola is a little over 116.6 grams. Most jewellers now quote gold rates per 10 grams, so convert before you compare prices.
How many cents make one acre?
100 cents make one acre, and one cent is 435.6 square feet. The unit is used mainly in Kerala, Tamil Nadu, Karnataka and Andhra Pradesh.
How do I convert Celsius to Fahrenheit by hand?
Multiply the Celsius value by 9, divide by 5, then add 32. So 30 °C becomes 30 × 9 ÷ 5 + 32 = 86 °F. To go the other way, subtract 32 and multiply by 5/9.
Is 1 GB 1,000 MB or 1,024 MB?
Both are used. In decimal units, which storage makers use, 1 GB is 1,000 MB. In binary units, used by Windows and many apps, the 1,024-based unit is properly called a GiB. The converter shows both.
