What Is a Quid? Quid vs. Pound Explained
By Forex & Brokers DeskUpdated Nov 10, 2026
Definition
A quid is British slang for one pound sterling (£1), worth 100 pence. It is used in casual speech, while coins, banknotes, banking and forex markets always use the pound, written £ or GBP.
Key takeaways
- A quid is slang for £1, the British pound sterling, worth 100 pence. The plural is usually just "quid."
- The word dates to the late 17th century, and its origin is uncertain.
- The pound sterling is often described as the oldest currency still in use, with roots in Anglo-Saxon silver pennies from around 775 A.D.
- In forex markets the currency is always quoted as GBP.
A quid is British slang for one pound sterling (£1), the official currency of the United Kingdom. One quid equals 100 pence. The word is informal: it appears in everyday speech and casual writing, but never on coins, banknotes, bank statements or exchange-rate quotes, where the currency is always the pound (symbol £, ISO code GBP).
So the difference between quid and pound is a difference of register, not value. “Ten quid” and “£10” are the same amount of money.
What a Quid Means in UK Money
When someone in the UK says something costs “a quid,” they mean £1. “Two quid” is £2, “10 quid” is £10, and “60 quid” is £60. The word works like “buck” for the US dollar: a casual stand-in for the currency’s main unit.
Quid is not an American term and does not refer to the dollar. It belongs to British English and is understood across England, Scotland, Wales and Northern Ireland, the four countries that make up the UK.
Grammar: Why It’s “Five Quid,” Not “Five Quids”
Quid is almost always used with a singular form even for plural amounts. A British speaker would say “that cost me 30 quid.” The main exception is the fixed phrase “quids in,” covered below.
Quid normally counts whole pounds. Pence are given separately, either as an exact figure (“£3.50”) or casually (“three quid fifty”).
Quid vs. Pound
| Quid | Pound | |
|---|---|---|
| Type of word | Slang, informal | Official currency name |
| Value | £1 | £1 (100 pence) |
| Used on coins and notes | No | Yes, as “£” and “pound” |
| Used in contracts, invoices, banking | No | Yes |
| Forex code | None | GBP |
| Plural | Usually “quid” | “Pounds” |
The pound is the legal currency name, as “dollar” is for the US; quid is a nickname for one unit of it. You would write “£250” on an invoice but might tell a friend the repair cost “250 quid.”
A related distinction sometimes confuses readers: sterling is the name of the currency as a whole, and the pound is its unit. China’s currency has a similar split, covered in yuan vs. renminbi.
Origins of the Word “Quid”
The word appears in English from the late 17th century, but how it became attached to money is unclear. Three explanations circulate:
- Latin “quid.” The word means “what” or “something” in Latin and appears in the phrase quid pro quo, “something for something.” A coin exchanged for goods fits that sense of a thing given in return.
- Italian “scudo.” Some link it to the scudo, the name for gold and silver coins of various denominations used in Italy from the 16th to the 19th century, possibly carried into English by Italian immigrants.
- Quidhampton. A village in Wiltshire, England, was home to a paper mill that produced paper for banknotes. One theory holds that paper money from the mill came to be called a quid.
None of these is confirmed.
A Short History of the Pound Sterling
Historians trace sterling to around 775 A.D., when Anglo-Saxon kings issued silver pennies known as sterlings. A pound weight of silver produced 240 of these pennies, which is where the name “pound sterling” comes from.
The £ symbol comes from Latin. Libra means a balance or weight, and libra pondo means “a pound by weight.” The old pre-decimal system was written £sd: pounds (librae), shillings (solidi) and pence (denarii).
Key points in the currency’s development:
- 1489: The first pound coin, the gold sovereign, was introduced under King Henry VII.
- Early 1500s: Shillings entered circulation. The structure became 12 pence to a shilling and 20 shillings to a pound, so 240 pence to a pound.
- 1694: The Bank of England was founded under King William III and began issuing banknotes.
- 1717: Britain effectively moved from a silver standard to a gold standard, so sterling was no longer tied to silver in practice.
- 1971: Decimalization, introduced on 15 February 1971 (“Decimal Day”), replaced 240 pence with 100 new pence to the pound.
Modern pound coins and notes contain no silver, but the name “sterling” survives. The pound also served as the currency of several former British colonies, including Australia, New Zealand and Canada, before they adopted their own currencies.

Idioms That Use “Quid”
- Quid pro quo: an exchange of one thing for another. “Her funding came as quid pro quo for a share of the profits.” The phrase is Latin, not money slang.
- Quids in: in a profitable or advantageous position. “After selling the flat above the asking price, they were quids in.”
- Not worth a quid: of little or no value.
- In for a penny, in for a pound: once you have committed to something, you may as well commit fully. “Quid” sometimes replaces “pound” in casual versions.
How a Quid Converts to Other Currencies
A quid has no exchange rate of its own. To find what a quid is worth in euros, dollars or Canadian dollars, convert £1 at the current GBP rate for that currency. Those rates float and can change from minute to minute during market hours.
Formula: amount in quid × GBP/XXX rate = amount in the other currency
Hypothetical example (rates are illustrative, not current): Say GBP/EUR is 1.15 and GBP/CAD is 1.85.
- 50 quid in euros: 50 × 1.15 = €57.50
- 150 quid in Canadian dollars: 150 × 1.85 = C$277.50
The same applies to slang amounts: “a tenner” in euros is 10 × the GBP/EUR rate. Banks and exchange bureaus usually give a rate less favorable than the mid-market rate, so you may receive less than the formula suggests.
Quid in Forex Trading
In currency markets the pound appears only as GBP, in pairs such as GBP/USD, EUR/GBP and GBP/JPY. Traders do have their own nicknames: GBP/USD is widely called “cable,” a reference to the transatlantic telegraph cable once used to send exchange rates between London and New York. “Quid” is not used as a market convention, ticker or quote label.
One point about pair notation trips up beginners. In GBP/USD, the pound is the base currency and the quote shows how many US dollars one pound buys. In EUR/GBP, the pound is the quote currency, and the number shows how many pounds one euro buys. Reading the pair backward turns a conversion into its inverse.
Limitations of the Term
- Not for formal use. Contracts, invoices, price tags and financial statements use “£” or “GBP”; writing “quid” can look careless or create ambiguity.
- Whole pounds only. Exact amounts with pence still need the £ figure.
- Regional and informal. Outside the UK, especially in the US, listeners may not know the word or may assume it means a dollar.
- No market meaning. Conversions and trades must use GBP.
The Bottom Line
The term matters to travelers, newcomers to the UK and anyone reading British prices or conversation. Quid and pound carry the same value, so ten quid is simply £10. For contracts, invoices, currency conversions and forex trades, use £ or GBP, since quid has no formal or market meaning and its own exchange rate does not exist.
