Temperature
Temperature is not a simple multiplication, because the scales start at different points. To go from Celsius to Fahrenheit, multiply by 9/5 and add 32. To go back, subtract 32 and multiply by 5/9. Kelvin is Celsius plus 273.15. Water freezes at 0 °C (32 °F) and boils at 100 °C (212 °F).
Marla and kanal
Land in Pakistan and parts of India is often measured in marla and kanal. This converter uses 1 marla = 272.25 square feet and 1 kanal = 20 marla = 5,445 square feet. Some housing societies use a 225 square foot marla instead, so check the local standard before you buy or sell land.
US and UK measures
Cups, pints, quarts and gallons use US sizes unless marked UK. A UK gallon (4.546 litres) is about 20% larger than a US gallon (3.785 litres).
