A US shot is usually counted as 1 1/2 fl oz, though no law fixes the size and some shot glasses are bigger. In kitchen terms that pour is 3 tablespoons, or 9 teaspoons, a little under 1/4 cup.
There is no cup measure for this amount, so a tablespoon is the cleanest tool. Three level spoonfuls of vanilla, liqueur or lime juice land right on 1.5 fl oz (about 44 mL). If you only have a 1/4 cup, fill it and pour off a bit more than one tablespoon.
For a cocktail recipe that says "1 1/2 oz," the ounces are fluid ounces. A baking recipe that lists 1.5 oz of nuts or chocolate means weight, and that needs a scale. The ounces to cups chart covers the nearby pours.
