How do I convert kilograms to pounds?

Multiply the kilograms by 2.20462 to get pounds. For example, 5 kilograms times 2.20462 equals 11.0231 pounds, which most people round to 11.02 pounds. To go the other way, multiply pounds by 0.453592 to get kilograms. The converter above does both directions for you, and it shows the exact factor it used.

How many centimetres are in an inch?

There are exactly 2.54 centimetres in one inch, by international agreement, so the conversion is exact rather than approximate. To convert inches to centimetres, multiply by 2.54, and to convert centimetres to inches, divide by 2.54 or multiply by 0.393701. For example, 10 inches equals 25.4 centimetres, and 100 centimetres equals 39.3701 inches.

One inch was defined as exactly 25.4 millimetres by the international yard and pound agreement of 1959, adopted by the United States, the United Kingdom and other countries, according to the National Institute of Standards and Technology (NIST).

What is the easiest way to convert kilometres to miles?

Multiply kilometres by 0.621371 to get miles, or divide miles by 0.621371 to get kilometres back. A quick mental shortcut is to multiply kilometres by 0.6 and add a little more, since 5 kilometres is about 3.11 miles rather than exactly 3 miles. For road trips or race distances, use the converter above for the exact figure.

How do I convert litres to gallons?

Multiply litres by 0.264172 to get US gallons, so 10 litres equals about 2.6417 gallons. To convert gallons back to litres, multiply by 3.78541, so 1 gallon equals 3.78541 litres. Be careful with the word gallon, because a UK imperial gallon is larger, at 4.54609 litres, and this converter uses the US gallon.

How do I convert Celsius to Fahrenheit?

Multiply the Celsius temperature by 9, divide by 5, and then add 32 to get Fahrenheit. For example, 20 degrees Celsius times 9 divided by 5 is 36, plus 32 gives 68 degrees Fahrenheit. To go back, subtract 32 from Fahrenheit, multiply by 5, and divide by 9. The converter above handles both directions, including temperatures below freezing.

The table above is generated from the pair you select, so it always matches the converter. Change the pair to see the common conversions for that unit, from 1 to 10 for most units, or the familiar temperatures for Celsius and Fahrenheit.
