Unit conversions come up more often than you might think — from checking your luggage weight before a flight to scaling a recipe from cups to millilitres. This guide covers the most common conversions and when you are likely to need them.
Weight conversions are among the most searched worldwide. Kilograms are the global standard, but pounds are still widely used in the United States, the United Kingdom for body weight, and across aviation and shipping industries. Knowing that 1 kg equals 2.205 pounds is a useful shortcut you will reach for often.
Length conversions matter most when shopping internationally. Clothing and screen sizes are listed in inches in the US but centimetres across much of Europe and Asia. Height is another common pain point — a person who is 170 cm tall is 5 feet 7 inches, which is not obvious without a converter.
Volume conversions are essential in the kitchen. Most recipes from the United States use cups, tablespoons, and fluid ounces, while the rest of the world works in millilitres and litres. 1 cup equals 236.6 ml, and knowing this can save a recipe from disaster.
Temperature conversions matter when travelling, following international weather reports, or cooking with ovens calibrated in different scales. Water boils at 100°C, which is 212°F — a useful anchor point for any temperature calculation.
Use the converters in the menu above to get instant, accurate results for all of these and more.
