Questions
How many kilometers are in one mile?
There are 1.609344 kilometers in one mile, and 0.6213711922 miles in one kilometer.
How do I convert miles to kilometers?
To convert miles to kilometers, multiply the number of miles by 1.609344. For example, 5 mi = 8.04672 km.
What can I type in the conversion box?
A number, a unit and the unit you want, like “5 ft 10 in to cm”, “72 °F in C”, “3 cups to ml” or “60 mph to km/h”. It understands symbols, full names, plurals and British spellings, adds mixed units such as feet and inches together, and accepts fractions like 1 1/2 or ½. Leave out the second unit to see the value in every common unit.
Which units does the converter know?
448 units in 36 categories: everyday measures of length, weight, volume, temperature, area, speed and time, technical ones like pressure, energy, torque, viscosity and radiation, and regional units such as the Japanese tsubo, Chinese jin, Indian tola and Russian verst.
How accurate are the conversions?
They use exact definitions wherever one exists (an inch is exactly 2.54 cm, a pound exactly 0.45359237 kg) and show 10 significant figures. A few units have varied over time or by region; those are marked, and the value in common modern use is the one used.
Are US and UK gallons the same?
No. A US gallon is 3.785 litres and a UK (imperial) gallon is 4.546 litres, and pints, quarts and fluid ounces differ in the same way. Both are listed separately, and the plain names mean the US ones.
Is a kilobyte 1000 or 1024 bytes?
A kilobyte (kB) is 1000 bytes, as with every other metric prefix. 1024 bytes is a kibibyte (KiB), and the same goes for MB and MiB, GB and GiB. Disk makers use the first; many operating systems show the second, which is why a 1 TB drive shows up as about 931 GB.
Why can't I convert cups to grams, or kilograms to litres?
Volume and weight measure different things, so the answer depends on what's being measured: a cup of flour weighs far less than a cup of honey. The converter only converts between units of the same kind, and tells you when two units can't be converted.
Part of Unit Converter
