Katha ↔ Sq Ft Bigha ↔ Acre Cent ↔ Sq Ft RFT ↔ Sq Ft Brass ↔ Cu Ft

What is the difference between Cent, Guntha, and Katha in India?

These are regional land units: **1 Cent = 435.6 sq ft** (used in South India: TN, Kerala, AP) | **1 Guntha = 1,089 sq ft** (used in West/South India: Maharashtra, Gujarat, Karnataka) | **1 Katha = 1,361 sq ft** (in Bihar) or **720 sq ft** (in West Bengal). 1 Acre is universally **43,560 sq ft**.

Conversions: 1 Acre = 43,560 sq ft = 40 Gunthas = 100 Cents = 8 Kanals  |  1 Hectare = 2.471 Acres = 10,000 sqm
1 Square Foot = 0.092903 Square Meter
Formula: multiply by 0.092903

* Regional conversions use widely accepted values; verify with local authorities.

📏 Construction & Material Conversion (High Intent)

For engineers, contractors, and procurement professionals, accurate material conversion is critical. Our converter includes specialized construction units:

  • Running Feet (RFT) to Square Feet: For flooring, multiply RFT by width in feet.
  • Brass to Cubic Feet: 1 Brass = 100 Cubic Feet (used for sand/aggregate).
  • Metric Ton to Cubic Meter (Concrete): Approx 2.4 tonnes per m³.
  • Gauge to mm (Steel Sheet): Based on standard gauge charts.
  • Cubic Feet to Liters: 1 ft³ = 28.3168 L.
  • Newton to kg: For pressure testing (1 N = 0.10197 kgf).
  • BTU to kW: For HVAC (1 kW = 3412 BTU/h).

🌍 Global Trade Standards: US vs Imperial vs Metric

International projects often require switching between US customary, Imperial (UK), and Metric systems. Key differences:

  • Gallon: US gallon = 3.785 L; UK gallon = 4.546 L.
  • Ton: Short ton (US) = 907.18 kg; Metric ton = 1000 kg; Long ton (UK) = 1016 kg.
  • Inch: 1 inch = 25.4 mm exactly.
  • Acre: 1 acre = 4046.86 m² = 43560 sq ft.

Our tool seamlessly handles these variations to avoid costly errors.

Varies by state: UP = 27,225 sq ft; MP = 14,400; Rajasthan = 27,255 (Pucca).

1 Cent = 435.6 sq ft (Kerala/TN).

1 Gaj = 1 Sq Yard (identical).

1 Kanal = 20 Marlas. 1 Marla = 272.25 sq ft.

10,000 m².

RFT is linear length. Area = RFT × width (ft).

1 Brass = 100 Cubic Feet.

3,785.41 mL.

In construction, 1 Brass represents a volume of 100 cubic feet (CFT) or an area of 100 square feet for plastering/roofing. To convert area from square feet to Brass, divide the total square footage by 100 (e.g., 500 sq ft = 5 Brass).

Decimal and Cent are identical measurements of area used in different states of India. Both represent exactly 1/100 of an acre, which is equal to 435.6 square feet or approximately 40.47 square meters.

Varies; common widths 36"-58". 1 running meter = length × width.

~18.15 Grounds (1 Ground = 2400 sq ft).

Use gauge chart; approximate: 16 gauge = 1.5 mm steel.

1 Lakh sq ft = 100,000 sq ft ≈ 2.295 acres.

1 Hectare = 100 Are.

Running feet (RFT) and running meters (RMT) measure linear lengths. Since 1 meter is equal to 3.28084 feet, you convert running feet to running meters by dividing the total running feet by 3.28084 (or multiplying by 0.3048).

No, they are different regional land units. 1 Guntha is equivalent to 1,089 square feet (standard in Maharashtra and Karnataka), whereas 1 Cent is equivalent to 435.6 square feet (standard in South India).

In Punjab and Haryana, 1 Biswa is equal to 1.25 Marlas, which is equivalent to approximately 340.31 square feet. However, in Uttar Pradesh, 1 Biswa is usually larger, measuring 1,350 square feet.

Area = linear feet × height.

UP: ~125.42 sq yd; varies regionally.
