Unit conversion is a multi-step process that involves multiplication or division by a numerical factor; selection of the correct number of significant digits; and rounding. Accurate unit conversions are obtained by selecting an appropriate conversion factor (a ratio which converts one unit of measure into another without changing the quantity). 

Note: These approximate approximate conversion factors are published as NIST SP 365, which is a laminated metric conversion card. Copies of this publication can be requested by contacting theSI [at] nist.gov

    US and imperial units

    The American system is based on British measures before the Reform of 1826, when the British Empire system of measures was officially introduced. Until the 1960s, US and UK length measures differed by 2 parts per million. At first, such a small difference did not cause problems, but by the middle of the 20th century, the accuracy of measurements increased and the difference could no longer be ignored. Countries have agreed to adjust their length measurement systems so that the unit values ​​are exactly the same. Since then, British and American length units have been identical. In the USA, the old version of the units of length was retained under the special name «Surveying Units»

    Since 1995, the UK has completely switched to metric units. Now, from non-metric measures of length, only miles, yards and feet are officially allowed to be used for road signs.

    British units before 1963

    The first official standards for units of measurement in Britain appeared in the 15th century. A single British system of units, measures of the British Empire, was introduced in 1824. Later at 1963g measures were synchronized between the US and UK and redefined in terms of the standard Parisian definition of the metre.

    International nautical units

    The international nautical mile was determined in 1929 at the International Extraordinary Hydrographic Conference. Now this definition is accepted by the International Bureau of Weights and Measures and is widely used throughout the world. Prior to 1929, different nautical mile values ​​were used in different countries. In particular, the USSR, Great Britain and the USA did not immediately switch to a single international value, but for some time continued to use their own versions of the nautical mile.

    Units of distance from Grace Hopper

    Grace Hopper is famous for having figured out how to visualize the concept of a nanosecond. She was often asked why satellite communications take so long. For clarity, Grace began to give out pieces of wire about 30 centimeters long, since that is how much light travels in one nanosecond. She also handed out packets of ground peppers, which she called picoseconds. Grace also used these visual aids to demonstrate why fast computers need to be small.
