Frequently asked questions
How many centimeters are in an inch?
There are exactly 2.54 centimeters in an inch. The international yard and pound agreement of 1959 defined the inch as 25.4 millimeters, so a foot is exactly 30.48 centimeters.
How do I convert Celsius to Fahrenheit?
Multiply the Celsius value by 1.8 and add 32. For example, 20 °C × 1.8 + 32 = 68 °F. To convert back, subtract 32 and divide by 1.8.
How many pounds are in a kilogram?
One kilogram is about 2.2046 pounds. The international pound is defined as exactly 0.45359237 kilograms, so dividing a value in kilograms by that number gives pounds.
Is a US gallon the same as an imperial gallon?
No. A US gallon is exactly 3.785411784 liters, while the imperial gallon used in British measurements is exactly 4.54609 liters, about 20 percent larger. US and imperial fluid ounces, pints and quarts differ too.
