A unit converter helps you transform measurements between different units and systems, such as metric to imperial or Celsius to Fahrenheit. Whether you are a student solving physics problems, an engineer calculating technical specifications, or a traveler converting distances, this tool provides instant and precise conversions for length, weight, area, volume, and temperature.
What Does This Unit Converter Do?
This tool instantly converts between different measurement units across multiple categories: length (metres, feet, inches, kilometres, miles), weight (kilograms, pounds, grams, tonnes), temperature (Celsius, Fahrenheit, Kelvin), area (square metres, square feet, kanal, marla), volume (litres, gallons, cubic metres), and speed (km/h, mph, knots).
The area conversions are particularly relevant for Pakistan — the kanal and marla are the standard land measurement units used in property transactions in Punjab, KP, and AJK. This tool converts them to and from standard metric units instantly.
How to Use This Calculator
- Select a category (length, weight, temperature, area, volume, or speed).

Key Conversion Factors for Pakistan
Land Area (Pakistan):
1 Marla = 272.25 sq ft = 25.29 sq metres
1 Kanal = 20 Marla = 5,445 sq ft = 505.857 sq metres
1 Acre = 8 Kanal
Weight: 1 kg = 2.20462 lbs = 1,000 g
Length: 1 foot = 30.48 cm = 12 inches
Temperature: °F = (°C × 9/5) + 32
Worked Examples
- Property size: A 10 marla plot = 10 × 272.25 = 2,722.5 sq ft
- Temperature: 42°C (Karachi summer) = (42 × 9/5) + 32 = 107.6°F
- Weight for visa: 50 lbs luggage allowance = 50 ÷ 2.20462 = 22.68 kg
- Speed limit: UAE speed limit 120 km/h = 120 ÷ 1.60934 = 74.6 mph
Practical Use Cases
- Property purchase: Convert property listings between marla, kanal, square feet, and square metres to compare plots across different listing sites that use different units.
- International recipe conversion: Convert cups to ml, ounces to grams, or Fahrenheit oven temperatures to Celsius for recipes from US or UK cookbooks.
- Luggage weight checks: Airlines specify limits in kg or lbs depending on origin. Convert between the two before packing to avoid excess baggage fees.
- Medical measurements: Convert body weight between kg and lbs for Pakistani patients using foreign pharmaceutical dosing charts (which often use lbs).
Marla and Kanal: Pakistan Land Units Explained
In Punjab, KPK, and AJK, residential and commercial land is measured in marla and kanal. A standard marla is 272.25 sq ft (though some older systems use 225 sq ft). Property advertisements in Pakistan typically list plot sizes as "5 Marla," "10 Marla," "1 Kanal," or "2 Kanal." When comparing with international property listings or mortgage calculations requiring square metres, this tool does the conversion instantly.
Common Mistakes to Avoid
- Marla size varies by region: Lahore Development Authority (LDA) and the Punjab standard marla is 272.25 sq ft. Some Karachi-based developers use square yards or square metres exclusively. Always confirm the local definition before signing a property agreement.
- Using Fahrenheit as Celsius: A patient temperature of 98.6°F (normal body temperature) is NOT the same as 98.6°C (which would be immediately fatal). Always confirm the unit before interpreting temperature values.
Frequently Asked Questions
How many square feet is 1 kanal in Lahore?
1 kanal in the standard LDA/Punjab system = 20 marla × 272.25 sq ft = 5,445 square feet. This is the most commonly used definition in Lahore, Islamabad, and most of Punjab.
What is the difference between kanal and acre?
1 acre = 8 kanal = 43,560 sq ft. Agricultural land in Pakistan is often quoted in acres. Residential land uses kanal and marla. This tool converts between both.
How do I convert km/h to mph for UK driving?
1 km/h = 0.621371 mph. The UK uses miles per hour. 100 km/h = 62.1 mph. Common reference: the M25 motorway speed limit is 70 mph = approximately 113 km/h.
