The American System (US Customary Units) and British Imperial Measures

American weights and measures are based on units used in Britain prior to 1826, when imperial system was officially established. Until 1960-1963 American and British units of length were different in 2 parts per million. In the middle of 20th century it started causing problems and the governments of the two countries agreed to refine the measures to exactly match. Since then Great Britain and the United States were using the same measures of length. In the U.S. the old standard of foot was retained with the name US survey foot.

From 1995 the UK adopted metric units for general use. The only imperial measures of length that can be officially used now are miles, yards, feet and inches for road traffic signs.

British Imperial Measure before 1963

The first English official measurement standards were defined in 15th century. British system of units, known as imperial units, was established in 1824. The British Weights and Meausurements Act of 1824 repealed all existing British measures legislation and redefined existing units. The 1963 Weights and Measures Act standartized the international measures.

International Nautical Measure

The international nautical mile was defined by the First International Extraordinary Hydrographic Conference, Monaco in 1929. This is the only definition in widespread current use, and is the one accepted by the International Bureau of Weights and Measures. Before 1929 different countries had different definitions, and the Soviet Union, the United Kingdom and the United States did not immediately accept the international value.

Grace Hopper's units of distance

Grace Hopper is famous for her nanoseconds visual aid. People used to ask her why satellite communication took so long. She started handing out pieces of wire that were just under one foot long (11.80 inches) — the distance that light travels in one nanosecond. She also passed out packets of pepper, calling the individual grains of ground pepper picoseconds. She also used these aids to illustrate why computers had to be small to be fast.

Does convert-me.com really exist since 1996? In fact it's even older. We launched the first version of our online units converter in 1995. There was no JavaScript there and all conversions had to be done on server. The service was slow. A year later the technology allowed us to create an instant units conversion service that became the prototype of what you see now.
