How It Works
Volume measurements in the UK can be confusing because UK gallons, pints and fluid ounces differ from US equivalents. A UK pint is 568 ml while a US pint is only 473 ml. This converter distinguishes between UK (imperial) and US measures to avoid errors.
The converter supports litres, millilitres, UK gallons, US gallons, UK pints, US pints, UK fluid ounces, US fluid ounces, cups (US standard) and tablespoons. It is useful for cooking (recipe conversions), fuel economy and liquid measurements in general.
UK volume units. 1 litre = 1.760 UK pints = 0.220 UK gallons. 1 UK pint = 568 ml (US pint 473 ml). 1 UK gallon = 8 pints = 4.546 litres (US gallon 3.785 L). 1 cup UK = 284 ml (legacy); cup US = 237 ml. UK still uses pints for: beer/cider in pubs (legal requirement), milk in glass bottles. Fuel sold in litres since 1995. Pub pint glasses must be 568 ml ±2% with HM Government crown stamp.
UK drink and container volumes. Pub beer pint 568 ml; half-pint 284 ml. Wine glass: small 125 ml, medium 175 ml, large 250 ml. Bottle wine 750 ml = 6 medium glasses. Spirits bottle 700 ml. Champagne 750 ml = 6 flutes. Single shot (England/Wales): 25 or 35 ml (pub displays). Scotland default 25 ml. Soft drinks: can 330 ml, bottle 500 ml, big bottle 2L. Milk: 1L or 2-pint (1,136 ml) or 4-pint (2,272 ml).
Cooking volumes. Soup recipe scaling: 250 ml/portion starter, 400 ml main. Coffee: filter 30g per 500 ml water; espresso 18-20g per 36 ml. Cooking wine: ½ bottle (375 ml) typical for boeuf bourguignon. Stock cubes: 1 cube = 500 ml. Tinned tomatoes 400g ≈ 6 medium fresh. Yorkshire pudding tin oil: 1 tsp per hole. Always measure liquids at eye level — meniscus convex for water-based, concave for syrup/oil.
Industrial and shipping volumes. Petrol tanker road: 38,000 L average. Domestic oil tank: 1,200-1,800 L typical. Heating oil minimum delivery: 500 L. UK skip sizes: mini 2 yd³ (1.5 m³); midi 4 yd³; builder's 6-8 yd³; RoRo 20-40 yd³. Shipping container: 20ft = 33 m³; 40ft = 67 m³. Water bills: m³ (1,000 L = 1 m³). UK average household 100-150 m³/year. Olympic swimming pool: 2,500 m³.
Volume in physics and engineering. Density formula: ρ = mass ÷ volume. Water density 1 g/ml at 4°C. Iron 7.87 g/cm³; gold 19.3 g/cm³; balsa wood 0.13 g/cm³. Boyle's Law: P×V = constant (at constant temperature). Charles's Law: V/T = constant (at constant pressure). Ideal Gas Law: PV = nRT. Practical: car tyre pressure increases when hot (warming a closed volume). Hot air balloon: heating air reduces density, less than surrounding air — lift.

- 2 UK gallons = 9.092 litres
- 2 UK gallons = 2.402 US gallons
- 2 UK gallons = 16 UK pints
