In the first decades of the 18th century in the Dutch Republic, Daniel Fahrenheit made two revolutionary breakthroughs in the history of thermometry. He invented the mercury-in-glass thermometer (first widely used, accurate, practical thermometer) and Fahrenheit scale. Fahrenheit has been the first standardized temperature scale to be widely used, although its use is now limited. It is the official temperature scale in the United States (including its unincorporated territories), its freely associated states in the Western Pacific (Palau, the Federated States of Micronesia and the Marshall Islands), the Cayman Islands, and Liberia. Fahrenheit is used alongside the Celsius scale in Antigua and Barbuda and other countries which use the same meteorological service, such as Saint Kitts and Nevis, the Bahamas, and Belize. A handful of British Overseas Territories still use both scales, including the British Virgin Islands, Montserrat, Anguilla, and Bermuda. In newspapers in the United Kingdom, degrees Fahrenheit figures are sometimes used in headlines for the sensationalism of heatwaves. All other countries in the world now officially use the "Celsius scale", the name given to the "centigrade scale" in 1948 in honor of Swedish astronomer Anders Celsius.
