True: British road signs show speed limits in miles per hour (mph). The mile used in the UK is an old unit of length, first standardised in 1593 by Queen Elizabeth I! It is equal to just over 1.6km. More on the Mile

False: The first person to run a mile in under 4 minutes was British medical student, Roger Bannister on 6th May 1954. At the time many people thought his achievement was impossible. 23 days Later, Diane Leather became the first woman to run under 5 minutes for the mile.

However, before the currency was decimalised in 1971 prices were much more complicated: Each pound had 20 shillings and each shilling had 12 pennies. That meant there were 240 pennies in a pound. People also spoke about crowns (5 shillings) half-crowns (2 shillings 6 pence) and even Guineas (21 shillings, or 1 pound and 1 shilling). Doesn’t that sound fun?!

However, some people still use it to talk about temperature… plus our American friends like it!
