1 imperial gill = 0.1420653125 liters

How to convert imperial gills to liters

To convert imperial gills to liters, multiply the number of imperial gills by 0.1420653125. This factor is exact. To go the other way, multiply liters by 7.039015946 (rounded).

liters = imperial gills × 0.1420653125

Example: 10 imperial gills = 1.420653125 liters.

Pints, quarts, gallons and fluid ounces differ between the US and the UK. Units are labeled 'US' or 'imperial' to avoid confusion.

About these units

Imperial Gill (gi (UK))

Imperial (British)Traditional unit (still used in some regions)

Five imperial fluid ounces, 142.07 mL, a quarter of an imperial pint. Formerly a UK spirits measure.

Gill, pronounced with a soft g, is the quarter pint of the imperial system: five imperial fluid ounces, or 142.0653125 milliliters, which is about 4.8 US fluid ounces. Four gills make a pint, eight make a quart and thirty-two make a gallon. The unit is also known as a teacup, and half a gill is sometimes called a jack.

Its best-known use was in selling spirits. Before metrication, English pubs poured spirits in sixths of a gill (about 23.7 mL), Scottish bars in fifths (28.4 mL) or quarters (35.5 mL), and Northern Ireland and the Republic of Ireland used the quarter gill. Scottish drinkers also had names such as the nip for a quarter gill and the wee gill for three quarters of a gill. After UK metrication, pubs moved to 25 mL or 35 mL measures, while the Isle of Man kept the one-fifth gill until 2022. Outside the drinks trade the gill is now rare and mostly appears in old recipes and statutes.

1 imperial gill = 0.1420653125 liters (exactly).

Liter (L)

Metric (SI)Current unit

One cubic decimeter (1,000 cm³). The everyday metric unit of volume for drinks, fuel and cooking.

The liter was born in revolutionary France. In 1795 it was introduced as a republican unit and defined as one cubic decimeter, while the gram was tied to a cubic centimeter of water. The name comes from the older French litron, itself descended from a Byzantine Greek unit of weight, not volume. A small revision of the decimeter in 1798 left the first liter about 1.000974 of today's cubic decimeter, and in 1879 the international metric authorities adopted the liter with the symbol l.

The liter then took a strange detour. In 1901 it was redefined as the space taken up by one kilogram of pure water at its densest, which made it about 1.000028 cubic decimeters, and that muddled definition lasted until 1964, when it was restored to exactly one cubic decimeter. A capital L was added as an alternative symbol in 1979 because a lowercase l is easy to mistake for the digit 1, and NIST says L is the symbol to use in the United States. A liter of water is close to a kilogram, which is why a one-liter bottle feels like a kilo in the hand.

The liter is the reference unit for volume on this site.
