About Imperial pint (imp pt)
The imperial pint is a unit of volume equal to one eighth of an imperial gallon, approximately 568.3 milliliters (20 imperial fluid ounces). It is the standard serving size for draft beer and cider in the United Kingdom, Ireland, and Australia. Despite UK metrication, the pint survives as the legally mandated unit for selling draft beer and milk in UK pubs and shops. The imperial pint is notably 20% larger than the US liquid pint (473 mL).
A pint of beer in a UK or Irish pub is exactly 568 mL (1 imperial pint). A UK pint of milk is 568 mL.
About Liter (l)
The liter (L) is the fundamental practical unit of volume in the metric system, defined as exactly one cubic decimeter (dm³) or 0.001 cubic meters. It is accepted for use with the SI but is not technically an SI base unit. The liter is the universal standard for beverages, fuel, and everyday liquid measurement in nearly all countries. One liter of pure water at 4°C has a mass of exactly one kilogram — a relationship that underpins many metric system conventions.
A standard 1-liter water bottle. A car petrol tank holds 40–70 liters. A human body contains roughly 5 liters of blood.
Etymology: From French "liter", derived from Old French "litron" (a unit of dry measure), from Medieval Latin "litra", from Greek "litra" (a monetary unit of weight in Sicily).
Imperial pint – Frequently Asked Questions
How many milliliters is a UK pint?
One imperial (UK) pint equals exactly 568.26 mL (20 imperial fluid ounces). A UK pint glass holds just over half a liter.
Why is beer still sold by the pint in the UK?
The UK is legally permitted to sell draft beer and cider in pints under exemptions to metrication rules. The pint is a protected official supplementary unit for draft alcohol. Milk may also be sold in pints.
Is an Irish pint the same as a UK pint?
Yes, an Irish pint is an imperial pint — 568 mL. A pint at an Irish pub is 20 imperial fluid ounces, identical to a UK pint.
How does an Australian pint compare to a UK pint?
In Australian pubs, a "pint" is technically 568 mL, but serving sizes vary by state. In South Australia and Western Australia, a "pint" is actually 425 mL. Australian glassware terminology is notoriously inconsistent.
How many fluid ounces are in an imperial pint?
One imperial pint equals exactly 20 imperial fluid ounces. A US pint equals 16 US fluid ounces. The fluid ounce sizes also differ slightly (28.41 mL imperial vs 29.57 mL US), compounding the pint size difference.
Liter – Frequently Asked Questions
How many milliliters are in a liter?
There are exactly 1,000 milliliters in one liter. This is one of the most fundamental metric relationships: 1 L = 1,000 mL = 1 dm³ = 1,000 cm³.
Why does 1 liter of water weigh 1 kilogram?
The kilogram was originally defined as the mass of one liter of pure water at 4°C (the temperature at which water is densest). Although the kilogram is now defined by the Planck constant, the relationship still holds to very high precision.
What is the difference between "liter" and "liter"?
"Liter" is the standard spelling in British English and most of the world. "Liter" is the American English spelling. Both refer to the same unit. The SI formally prefers "liter" but accepts both spellings.
How many liters are in a gallon?
One US liquid gallon equals approximately 3.785 liters. One imperial (UK) gallon equals approximately 4.546 liters. Because the two gallons differ by about 20%, fuel economy figures in L/100km and MPG do not convert directly without specifying which gallon.
How much blood does the human body contain in liters?
An average adult has approximately 4.5–5.5 liters of blood, with 5 liters being the commonly cited figure. Blood volume varies with body size, fitness, and altitude.
