Imperial Gills to Milliliters (gi (UK) to mL)

1 imperial gill equals 142.0653125 milliliters exactly.

1 imperial gill = 142.0653125 milliliters

How to convert imperial gills to milliliters

To convert imperial gills to milliliters, multiply the number of imperial gills by 142.0653125. This factor is exact. To go the other way, multiply milliliters by 0.007039015946 (rounded).

milliliters = imperial gills × 142.0653125

Example: 10 imperial gills = 1,420.653125 milliliters.

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).

Milliliter (mL)

Metric (SI)Current unit

One thousandth of a liter, or exactly 1 cubic centimeter. Used for medicine, cooking and small containers.

Milliliters inherit everything from the liter, since the prefix simply means one thousandth. Because the liter is a cubic decimeter, a milliliter works out to exactly one cubic centimeter, a coincidence the metric system built in on purpose so that volume, length and mass interlock. One milliliter of water has a mass of about one gram, so a dosing syringe, a kitchen scale and a measuring jug can all be checked against one another.

Today milliliters dominate wherever small amounts must be measured precisely: medicine, flavorings, perfume, shampoo and the fine print on drink labels. Spelling is a mild regional split, with uppercase mL preferred in the United States, Canada and Australia and lowercase ml common in the UK and Europe. For scale, a US teaspoon is just under 5 mL, a US tablespoon is about 14.8 mL, and the US nutrition-label cup is exactly 240 mL, so one such cup is 240 of these tiny units.

1 milliliter = 0.001 liters (exactly).
