About Unit Converter
This converter changes a value from one unit to another as you type. It covers seven groups: length, weight, temperature, area, volume, speed and storage. Choose a group, pick the unit you are converting from and to, enter a number, and the answer appears instantly.
Examples of what is included are metres, kilometres, feet, inches and miles for length; kilograms, grams, pounds and ounces for weight; Celsius, Fahrenheit and Kelvin for temperature; square metres, square feet, acres and hectares for area; litres, US gallons, quarts, pints and cups for volume; km/h, mph, m/s and knots for speed; and bytes up to terabytes for storage.
Two notes. Gallons, quarts, pints and cups are US units, which are smaller than the imperial ones used in the UK. Storage units here are binary, so 1 KB is 1,024 bytes and 1 GB is 1,024 MB, which is how computers usually report memory, while drive makers often use 1,000. Results are rounded to seven significant digits.
