About This Calculator
The UK Coin Weight Calculator helps you quickly determine the total weight of your UK coins based on the quantity of each denomination. Whether you are sorting loose change, preparing coins for a bank deposit, checking the weight of a coin collection, or simply curious about how much your spare change weighs, this tool provides instant and accurate results.
The calculator uses official coin specifications from the Royal Mint. Each coin's weight in grams is multiplied by the quantity entered to compute the total weight. The results can be displayed in grams (g), kilograms (kg), or ounces (oz). The calculator also shows the total face value of your coins and a detailed breakdown of weight and value per denomination. A bar chart visualises the weight contribution of each coin type, and a pie chart shows the proportional distribution.
The United Kingdom currently has eight circulating coins: 1p, 2p, 5p, 10p, 20p, 50p, £1, and £2. Their weights range from 3.56g for the 1p coin to 12.00g for the £2 coin. Knowing the weight of coins is useful for bulk counting, vending machine operations, charity collections, and understanding the physical properties of UK currency.
