Measurement is among the most important tasks in bar-tending and due to the diverse systems of measurement around the world perhaps the most confusing for a project such as ours. This page lists common liquid measurements in terms of fluid ounces and their metric equivalents.

Common bar measurements[edit]

Term Measurement (US) Measurement (Metric)
1 part any equal part any equal part
1 dash (*) 1/32 fl. ounce 0.92 mL
1 splash (*) 1/12 fl.ounce approximately 2-3 mL
1 teaspoon (tsp) 1/6 fl. ounce 4.93 mL
1 tablespoon (Tbsp.) or 'count' 1/2 fl. ounce 14.79 mL
1 pony 1 fl. ounce 29.57 mL
1 jigger 1 1/2 fl. ounces 44.36 mL
1 shot (†) 1 1/2 fl. ounces 44.36 mL
1 snit 3 fl. ounces 88.72 mL
1 wineglass 4 fl. ounces 118.29 mL
1 split 6 fl. ounces 177.44 mL
1 cup 8 fl. ounces 236.58 mL
1 pint (pt) 16 fl. ounces 473.17 mL
1 quart (qt) 32 fl. ounces 946.35 mL
1 fifth 25.6 fl. ounces
(1/5 gallon)
757.08 mL
1 gallon (gal) 128 fl. ounces 3785.41 mL
(*) The "dash" and "splash" are variable measurements with no formally agreed upon definition.
(†) A "shotglass" is usually 1.5 ounces, but sometimes 2 ounces with a measuring line at 1.5 ounces. You can also buy (in US) "short shot" glasses or "pony shots" which are 1 ounce. Pony shots are usually used with martinis, manhattans, and rob roys.


Dash and fill[edit]

Some recipes call for a small amount or "dash" to taste. A dash can be loosely defined as 1/6 teaspoon or about 1 mL, essentially the smallest amount one is able to pour from a dasher (a device which fits in the mouth of a bottle to slow the flow of liquid) or dasher bottle (a bottle equipped with such a device).

When instructed to 'fill' with a given spirit or mixer it is presumed that you are working in a glass of the given size and should, after adding the cocktail's other ingredients, 'top off' or fill the glass as instructed. If your recipe lists no specific glassware it may assume a standard highball glass of eight to ten ounces.
