Unit Converter

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

1. Select a category (length, weight, temperature, area, volume, or speed).
2. Enter the value you want to convert.
3. Select the From unit and the To unit.
4. Click Convert. The result is displayed instantly.

Key Conversion Factors for Pakistan

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.

Pakistan-Specific Measurements That Global Converters Get Wrong

Standard unit converters handle metric and imperial systems. What they almost never include are the traditional South Asian and local Pakistani units still in active daily use — especially in real estate, agriculture, and gold trading:

• Land measurements: Marla, Kanal, Bigha, and Acre are the dominant units in Pakistani real estate — not square meters or square feet. Key conversions: 1 Marla = 272.25 sq ft (25.29 sq meters). 1 Kanal = 8 Marla = 2,178 sq ft (202.3 sq meters). 1 Bigha varies by province: 1 Bigha Punjab ≈ 4,500 sq ft; 1 Bigha KPK ≈ 3,125 sq ft. Always confirm which regional Bigha is being used before signing a land deed.
• Gold weight: Gold in Pakistan is sold and priced by the tola. 1 Tola = 11.66 grams. When PMEX or jewellers quote gold prices per tola, this is the unit. Converting to grams: multiply tola by 11.66.
• Cooking units (desi vs metric): Recipes in Urdu often use pao, seer, and chhatak. 1 Seer = 933 grams. 1 Pao = 233 grams (quarter seer). 1 Chhatak = 58.3 grams. These are not in Google's unit converter.

Where Unit Conversion Mistakes Actually Cost Money

These are not theoretical errors — they happen in real transactions:

• Property purchases: A plot listed as "10 Marla" in Lahore vs "10 Marla" in Karachi may use different standard measurements. DHA Lahore, LDA, and KDA all define Marla as 272.25 sq ft — but some private housing societies use 225 sq ft per Marla. Always confirm the society's definition before negotiating price.
• Construction material orders: Cement bags, steel rods, and bricks are ordered in different units by different suppliers. Mixing metric tons and long tons (used in some steel quotations) is a 1.6% error that becomes significant at large volumes.
• Fuel and travel: Pakistan's fuel is sold in litres; vehicle fuel efficiency is often stated in km/L locally but some imported car specs list mpg (miles per gallon). 1 km/L = 2.35 mpg. Not knowing this leads to wrong range estimates.
• Jewelry and Gold (Tola vs Grams): Gold in Pakistan and the GCC is often priced per Tola or per 10 Grams. 1 Tola = 11.6638 grams (standardized). When buying from Dubai (priced in grams) and comparing to Pakistan (priced in Tola), converting incorrectly can lead to thousands of rupees in lost value.
• Import/export pricing: Commodities are often priced in metric tonnes internationally but traded in long tons or short tons depending on origin country. A 1.6% weight difference on a 100-tonne wheat order is 1.6 tonnes of financial exposure.

Real-World Decision Scenarios for Unit Conversion

• Buying a plot: The broker says it's 500 square yards. You think in Marla. 500 sq yd ÷ 30.25 = 16.5 Marla. Use this converter to instantly check before negotiating.
• Cooking for a large event: A recipe in cups needs scaling to kilograms for bulk buying. 1 cup of rice ≈ 190 grams. 50 cups = 9.5 kg. Buy 10 kg bags and have a small surplus.
• Checking fuel efficiency: Your car manual says 32 mpg highway. Convert: 32 × 0.425 = 13.6 km/L. At Rs. 280/litre, expect Rs. 20.6 per km — or Rs. 2,060 per 100 km. To estimate electricity usage cost for an EV, you can use our Electricity Bill Calculator.

The Most Common Unit Conversion Errors

• Temperature direction confusion: Celsius to Fahrenheit uses (°C × 9/5) + 32. People often forget the +32 and get a wrong result. 37°C (body temperature) = 98.6°F — not 66.6°F.
• Volume vs weight mixing: 1 litre of water = 1 kg. But 1 litre of oil ≈ 0.92 kg, and 1 litre of milk ≈ 1.03 kg. For anything other than water, volume and weight are not interchangeable.
• Square vs linear units: Doubling the length of a room increases its area by 4× (if width also doubles), not 2×. A 20% increase in room dimensions means a 44% increase in area.
