Reference guide · India measurement converter online

The complete guide to Indian measurement units — every state, every category.

If you have ever tried to buy land in Bihar using a Uttar Pradesh measurement standard, or walked into a Kerala gold shop expecting Tola prices and found Sovereign quotes, or watched a Punjab property agent describe a plot in Marla while the buyer’s bank insisted on square feet — you have experienced India’s measurement problem firsthand. This guide solves that problem completely.

India is unique in the world when it comes to measurement diversity. Every state uses different land units. Jewellery markets run on units that predate the metric system by centuries. Construction engineers order in cubic meters while vendors quote in CFT. This site exists to bridge every one of those gaps.

Bigha to square feet in UP, Bihar, Bengal — why state matters

The most-searched measurement conversion in India is bigha to square feet in up. Over 184,000 people search for this every month — more than any other land conversion query. The reason is simple: UP has India’s largest rural land market, and every transaction needs this number. 1 Bigha in UP = 27,225 sq ft exactly, as per the UP Revenue Code.

But here is where it gets complicated. The same word — Bigha — means something completely different in the next state. Bigha to square feet in Bihar gives you 27,220 sq ft, not 27,225. That 5-square-foot difference on a 100-Bigha plot adds up to 500 sq ft of land — a legally significant amount in any registered sale deed. And in West Bengal, the difference is even more dramatic: bigha to square feet in west bengal is just 14,400 sq ft, almost exactly half the UP standard.

The bigha to square feet in rajasthan calculator handles both the Pucca Bigha (27,225 sq ft, matching UP) and the Kuccha Bigha (17,424 sq ft, used in parts of western Rajasthan). Always confirm which standard your district uses before signing any documents. For hill states: bigha to square feet in uttarakhand is only 6,804 sq ft, because a Bigha was historically defined by how much land a single plough could work in a day, and mountain terrain simply covered less ground.

For North India sub-unit conversions: biswa to square feet calculator (1 Biswa = 1,361 sq ft in UP, 1/20 of a UP Bigha) and katha to square feet in bihar (1 Katha = 1,361 sq ft, 1/20 of a Bihar Bigha). For Bengal sub-units, use the chatak to square feet in west bengal calculator (1 Chatak = 45 sq ft, 1/16 of a Bengal Katha). For Assam, which has an entirely different hierarchy, use the lecha to square feet in assam calculator (1 Lecha = 144 sq ft).

Marla to square feet in Punjab, Kanal to square feet — North India urban land

Punjab and Haryana use a completely different measurement system from UP and Bihar. Here, the primary units are Marla and Kanal. The marla to square feet in punjab calculator handles the core conversion: 1 Marla = 272.25 sq ft. Twenty Marla make one Kanal, so the kanal to square feet in punjab calculator gives you 5,445 sq ft for 1 Kanal.

In Punjab property listings — Chandigarh, Ludhiana, Amritsar, Mohali, Patiala — you will see plots described as “5 Marla” or “1 Kanal”. To convert between these two units, use the marla to kanal calculator punjab. For the relation to acres, use the kanal to acres converter india calculator (8 Kanal = 1 Acre exactly).

In Haryana — Gurgaon, Faridabad, Panipat, Rohtak — the same Marla and Kanal standards apply as Punjab. These units also appear in Himachal Pradesh and J&K land records. For Delhi NCR plots, the standard unit is Gaj (square yard). The gaj to square feet calculator india converts 1 Gaj = 9 sq ft. DDA housing scheme plots are always sized in Gaj, and so are most resale properties in South Delhi, Noida, and Faridabad.

Cent to square feet in Tamil Nadu, Ground — South India land

South India uses completely different land units from the North. Tamil Nadu, Kerala, and parts of Andhra Pradesh measure land in Cent. The cent to square feet in tamil nadu calculator gives you 435.6 sq ft for 1 Cent (exactly 1/100 of an acre). Chennai property listings always use Cent for small residential plots.

For larger residential plots in Chennai, the unit is Ground. The ground to square feet in tamil nadu calculator gives you 2,400 sq ft for 1 Ground, approximately 5.5 Cent. This is the primary unit for premium residential land in areas like Anna Nagar, Adyar, and T. Nagar.

Karnataka, Andhra Pradesh, and Telangana use Gunta for small sub-acre plots. The gunta to square feet in karnataka calculator gives 1,089 sq ft (1/40 of an acre). In Maharashtra, the same unit is spelled Guntha: the guntha to square feet in maharashtra calculator uses the identical 1,089 sq ft factor, but Maharashtra’s official 7/12 (Satbara) land records use the Marathi spelling.

Hectare to acres, square meter to square feet — metric conversions for RERA

Government documents, RERA filings, and agricultural census data increasingly use metric units, even as buyers and sellers think in traditional ones. The hectare to acres converter india gives you 2.471 acres per hectare — essential for reading government land allocation documents. For apartment buyers, the square meter to square feet calculator (1 sq m = 10.764 sq ft) is the most important RERA-related tool on this site.

RERA mandates carpet area disclosure in square meters, but most buyers think in square feet. To convert your RERA document back to sq ft, multiply by 10.764, or use the square feet to square meter calculator in reverse. For the acre to square feet calculator india, the answer is 43,560 sq ft per acre — the universal constant that underlies virtually every Indian land measurement.

Tola to grams calculator India — gold and silver weight conversions

India is the world’s largest gold consumer, and the jewellery market still runs on units that predate the metric system by centuries. The tola to grams calculator india is the most important gold conversion for North Indian buyers: 1 Tola = 11.6638 grams. This is not a round number — it comes from the weight of the British Indian silver rupee coin.

When comparing a jeweller’s Tola-quoted price against the international spot price (quoted per 10 grams), divide by 1.16638. Our grams to tola converter india handles the reverse. To compare against global commodity prices: the troy ounce to grams calculator india (1 Troy Oz = 31.1035 g) is the conversion used by MCX gold futures and international bullion traders.

In South India — Kerala and Tamil Nadu — gold is measured in Sovereign and Pavan, both equal to exactly 8 grams. The sovereign to grams gold in kerala and pavan to grams gold in kerala calculators handle this. When Kerala channels report “today’s Sovereign rate,” they mean the price per 8 grams of 22-carat gold. For purity calculation of any karat: the gold karat purity calculator india gives you the percentage of pure gold in 22K (91.67%), 18K (75%), 14K (58.33%), and all other karats.

For gemstone weights and Ayurvedic dosages, the traditional unit is Ratti. The ratti to grams gem calculator india gives 0.1215 grams per Ratti. For older North Indian jewellery shops still using Aana and Masha: the aana to grams gold calculator india (0.729 g per Aana) and masha to grams gold calculator india (0.972 g per Masha) cover these traditional units.

CFT cubic feet calculator India — construction material ordering

Cup to grams atta flour calculator — Indian cooking measurements

Indian recipe books and cooking videos use cups, tablespoons, and traditional units that create confusion in the kitchen. The cup to grams atta flour calculator is the most-used cooking conversion: 1 cup of atta = 120 grams. For rice: cup to grams rice calculator india gives 185 grams per cup. For sugar: cup to grams sugar calculator india gives 200 grams per cup.

The key confusion is the Indian measuring cup (200ml) versus the international standard cup (240ml). Our indian cup to us cup converter handles this — when following American recipes, you need 1.2 Indian cups to equal 1 US cup. For basic spoon conversions: tablespoon to grams calculator india (15 g) and teaspoon to grams calculator india (5 g).

Traditional market units still used across India: pav to grams calculator india (1 Pav = 250 g, one quarter kg), seer to kg calculator india (1 Seer = 0.9331 kg), maund to kg calculator india (1 Maund = 40 Seer = 37.32 kg). These appear in old recipe books, Ayurvedic prescriptions, and wholesale grain markets.

India has different clinical BMI cutoffs from the global WHO standard. The bmi calculator for indians india uses ICMR-recommended values: Normal 18.5–22.9, Overweight from 23, Obese from 25. These lower cutoffs reflect the higher body fat percentage that Indians carry at any given BMI versus Caucasian populations.

For height conversion between the formats used in India: height feet inches to cm calculator and cm to feet inches height calculator handle both directions.

EMI calculator India home loan car loan — financial planning

The emi calculator india home loan car loan is the most-used financial tool on this site. It uses the standard PMT reducing balance formula: EMI = P×r×(1+r)^n / ((1+r)^n−1), where P = principal, r = monthly interest rate, n = tenure in months. This is the same formula used by SBI, HDFC, ICICI, and all RBI-scheduled banks.

For comparison with flat-rate loan products, the simple interest calculator india rupees calculates SI = P×R×T/100. The total interest on a flat-rate loan at the same stated rate is always higher than on a reducing-balance EMI loan — use both calculators to compare before signing.
