Use a liquid measuring cup for accurately measuring thin liquids such as milk, juice, and oil.
Put the cup on a flat surface to get an accurate measurement. Then, pour the liquid in until it reaches the correct measurement line.
Use the meniscus (or measurement line). Lean down until your reach an eye-level on the measurement cup.When you see the light concave curve in the surface of the liquid, make sure that the bottom touches the meniscus.
Use a measuring spoon for a small quantity of liquid. Use measuring spoon if you're measuring less than a quarter cup of a thin liquid.
To catch the excess liquid, hold the spoon over a separate bowl and gently pour in the liquid until the spoon is full.
Use a syringe in measuring a small amount of liquid. This tool can also give an accurate result of measurement for low volumes of liquid.
