Cocktail and Bar Measurements

Bartending » Cocktail and Bar Measurements

The cocktail recipes you find at are all based on the imperial standard of measurement that is used pretty much only by the United States. However, we've made it so that you, the thirsty global citizen, can see our recipes in all their international SI glory. You can set your display settings accordingly in your account settings if you've registered a username. This is a list of the conversion factors we use. Note that they are not precise in many cases, but it is easier to deal with 1 oz. converting to 3 cL rather than 2.957353 cL.

Some common terms and their measurements

Term Imperial Metric
Shot 1 1/2 oz. 4.5 cL
Jigger 1 1/2 oz. 4.5 cL
Cup 8 oz. 24 cL
Tablespoon (tbsp.) 1/2 oz. 15 mL
Gallon 128 oz. 3.8 L
Quart 1/4 gallon or 32 oz. ~ 1 L
Fifth 1/5 gallon or ~26 oz. 0.75 L
Dash or Splash 1/32 oz. (see below) (see below)


Many recipes on the site call for measurements in "parts". This is simply a relative measurement, often used for mixing large batches of drinks at once. So if the recipe calls for 1 part of ingredient A, and 2 parts of ingredient B, then you would use twice as much of ingredient B.

Shot Glasses

A proper shot glass is 1.5 oz., but many bars use "pony shots", which are only 1 oz. A double shot glass holds 3 ounces.

Dash or Splash

These are terms that simply refer to small amounts. When you are using dashes or splashes, you are flavouring a cocktail for taste, so it becomes a bit of a judgement call. Don't go overboard, but make sure you use enough to be noticed. A splash is a little more than a dash, and generally involves less viscous liquids such as mixers, whereas dashes are used with stronger flavourings, such as tabasco.
