Why did the UK get rid of fahrenheits scale?

Answer 1

The UK weather agency, the Meterological Office, switched to Celsius for its work in 1961, as it had become the international standard for measurement. In their words:

"The Celsius scale is the World Meteorological Organization standard for temperature measurement and is used throughout the world by the meteorological community for global exchange of information."

By 1962, public weather forecasts were being given in Celsius, albeit with Fahrenheit conversions. This probably had a significant impact on public perception and encouraged a gradual move from one system to the other.

Additionaly, Britain decided to convert its other systems of measurement to metric in 1965, primarily to support trade and international collaboration. It also converted currency from the old pound containing 240 pence to the more conventional decimal pound of 100 pence in 1971. These developments reinforced the shift away from the mix of old measures to the internationally-standard system using metres, kilograms, litres -- and Celsius.

Answer 2

The UK switched to the metric system in the 1960s, which uses Celsius rather than Fahrenheit. This was done to align with the rest of the world and facilitate easier international communication and trade. The Celsius scale is also seen as more scientifically and mathematically consistent.
