UK Coin Weight Calculator

The UK coin weight calculator helps you quickly find out how much your coins weigh based on quantity.

Coins in UK

As we can imagine, coins have been a very important part of the British Empire for centuries, evolving through the economic shifts. Today, the UK uses eight main coins: 1p, 2p, 5p, 10p, 20p, 50p, £1, and £2 (Remember that the 2p coin is no longer being produced. It's still in circulation, but it's becoming less common due to the lack of new coins being minted). The “p” stands for pence, a term that comes from the Roman denarius. Even though the UK moved to a decimal system in 1971, where 100 pence equals one pound, the historical names stuck.

Interestingly, while some countries phased out small coins, the UK still uses 1p and 2p coins, partly because of pricing psychology and tradition. The £1 and £2 coins were introduced fairly recently but are now firmly embedded in daily transactions.

UK coins by weight

Usually, each coin has a different weight, size, and shape to make it easy to tell them apart; it's the same thing with coins in the UK​.

Smaller coins like the 5p weigh just 3.25 grams, while bigger ones like the £2 coin are much heavier at 12 grams, and our UK coin weight calculator takes all of them into consideration. These weight and appearance differences help with everyday use, and machines like coin sorters or vending machines rely on them as well.

Below, you'll find a simple table showing all current UK coins and how much they weigh in grams, so you can understand UK coin bag weights.
