Factors for Converting Units of Volume This page contains a number of useful equivalences and conversion factors which can be used to equate the many units used to measure volume. When working out the amount of insecticide or weedikiller to use, it is important to get the measurement correct. Some are from a previous era and are rarely used to-day, but are interesting and useful if consulting old publications. The calculator below can be dragged around with your mouse for working out the conversion. Use these links to other pages of conversion factors.

Useful Volume Relationships

Imperial (GB)

Although they are called the same thing there is a difference between Imperial or GB measurements and those in the USA,
eg. 1 Imperial gallon = 0.1605 cubic feet and 1 US gallon = 0.1337 cubic feet

fluid ounce = 1/20th pint = 1/32nd quart = 1/160th gallon
1 cup (GB) = 10 fluid ounces = ½ pint (GB) = ¼ quart = 1/16th gallon
1 cup (US) = 8 fluid ounces = ½ pint (US) 1 pint (GB) = 20 fluid ounces = ½ quart = 1/8th gallon
1 quart = 40 fluid ounces = 4 cups = 2 pints = ¼ gallon
1 gallon = 160 fluid ounces = 8 pints = 4 quarts = 0.1605 cubic feet (GB) = 0.1337 cubic feet (USA)

Metric

1 millilitre = 1 cubic centimetre (cc, cm³) ie. 1cm x 1cm x 1cm
1 centilitre (cl) = 10 cubic centimetres
1 litre = 1000 cubic centimetres (cm³)
1 litre = 1 cubic decimetre ( ie. 10cm x 10cm x 10cm )
1 litre = 1/1000th of a cubic metre
1 British Standard metric teaspoon = 5 millilitres (ml)
1 British Standard metric tablespoon = 15 millilitres (ml)

In cookery dry ingredients are often measured out by volume, so the weight will vary depending on the density (see also Factors for Converting Units of Mass page). So a cupful of sifted flour is roughly half the weight of a cupful of granulated sugar. Also when given the volume in spoonsful it usually means a heaped spoonful of the dry ingredient with as much above the bowl of the spoon as in it. A spoonful of liquid ingredient would obviously be less.

Dry Measure 4 gills - 1 pint 2 pints = 1 quart 4 quarts = 1 gallon 2 gallons = 1 peck 4 pecks = 1 bushel 3 bushels = 1 bag 4 bushels = 1 coomb 5 bushels = 1 sack (flour) 8 bushels = 1 quarter 36 bushels (12 bags) = 1 chaldron 40 bushels (5 quarters) = 1 wey (horse-load) 2 weys = 1 last.

Liquid Measure 4 gills = 1 pint 2 pints = 1 quart 4 quarts = 1 gallon 9 gallons = 1 firkin 10 gallons = 1 anker 2 firkins = 1 kilderkin 2 kilderkins = 1 barrel 1½ barrels = 1 hogshead 2 hogsheads = 1 butt 2 butts = 1 tun

Cubic measure Note that when converting volume units, the linear and volume relationships are not the same. So a cubic foot is not 12 cubic inches, it is 12 inches cubed

1 cubic foot = 1728 cubic inches

ie. 12in x 12in x 12in.

12 cubic inches is approximately 2.289434in x 2.289434in x 2.289434in

1 cubic yard = 27 cubic feet
16 cubic feet = 1 cord foot
8 cord feet = 1 cord

Champagne Bottle Sizes

Type	Capacity	Number of bottles
Quarter	18.75 cl	¼
Half-Bottle	37.5 cl	½
Bottle	75 cl	1
Magnum	1.5 litre	2
Jeroboam	3 litre	4
Rehoboam	4.5 litre	6
Methuselah	6 litre	8
Salmanazar	9 litre	12
Balthazar	12 litre	16
Nebuchadnezzar	15 litre	20
Melchior (Solomon)	18 litre	24
Primat	27 litre	36

The for ease of handling the secondary fermentation which gives champagne its sparkle, is usually carried out in Magnum-sized bottles then decanted into the other sizes. A full Nebuchadnezzar weighs 38 kilograms and the Primat weighs 65 kg.
These bottle sizes are also used for some Fench wines with the addition of a Marie Jeanne (3 bottle) and Double Magnum (4 bottle) for Bordeaux - the Jeroboam for this wine contains 6 bottles. Needless to say they are usually served from a special cradle.
