To measure liquids, you should always use liquid measuring cups and spoons. Liquid measuring cups are usually glass or plastic, and most have a spout for pouring. Avoid dry measuring cups when measuring liquids. They will not be as accurate and could make a difference in the outcome of a recipe, which is especially important for baked goods.

Remember that the fluid ounces marked on the outside of the liquid measuring cups are not necessarily the same as ounces.

The fluid ounces are a measurement of volume while ounces are a measure of weight. Water and stock will be about the same weight in fluid ounces and weight ounces, but most liquids will be different. For instance, 1 cup of water or butter will be 8 ounces either way, but 1 cup of sweetened condensed milk will weigh around 11 ounces, and 1 cup of honey will weigh about 12 ounces.

Some scales have a liquid measuring feature for fluid ounces or milliliters. That would give you the option of adjusting the density of the liquid you are measuring.

Tips for Measuring Liquids

Set the liquid measuring cup on a flat surface. 

Bend or scooch down so you are eye level with the cup so that you can clearly see when the liquid is level with the measurement markings on the sides.

Measuring spoons, made to measure both dry and liquid ingredients, are not as accurate for liquid ingredients.

Since measuring cups don't measure such small increments, measuring spoons must be used for teaspoons and tablespoons of liquid (or, in most cases, anything under two fluid ounces). Be sure to fill the measuring spoon right to the rim for the best measurement.
