The primary language spoken here is British English, which features different terms and pronunciations than American English. Other common languages here include Gujarati, French and Turkish, but there are many others. London is a diverse city with up to 300 different languages spoken throughout the area, according to the B.B.C., the British national media outlet.
London's official currency is the pound terling (£), abbreviated as G.B.P. Banknotes (bills) come in denominations of £5, £10, £20 and £50, while coins are available in denominations of 1p, 2p, 5p, 10p, 20p, 50p, £1 and £2. "P" represents "pence," where 100p makes up £1, just like the relationship between the American penny and dollar.
The current conversion rate for U.S.D. to G.B.P. is approximately 1.34 U.S.D. to 1 G.B.P.
The exact amount that a bottle of water costs varies depending on where you buy from and the size of the bottle. At Sainsbury's, a British grocery store chain, a single bottle of water costs £1.25. I typically stick to my reusable water bottle, though, which can be challenging to fill as water stations are not as prevalent as in the U.S. Usually, however, tap water is available.
