Measuring Tip
For liquids, place your measuring cup on a flat surface and read at eye level. The bottom of the meniscus (the curve at the surface) should align with the measurement line.
Understanding the Units
What is a Quart?
The quart gets its name from "quarter" (of a gallon). One US quart is about 5.7% smaller than 1 liter (946 ml vs 1,000 ml). Always use the exact unit your recipe specifies.
What is an Ounce?
Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.
