What is the volume of liquid in a cylinder?
The numbers of milliliters, Liters, centiliters...on the side of the cylinder. Measure it at the line that the liquid is at.
A graduated cylinder is used to measure liquid volume in milliliters, mL. When you place a liquid into a glass graduated cylinder, you will see that the "line" at the top of the column of liquid is actually curved downward. This is called the meniscus. When you measure the liquid volume, you record the volume in mL at the bottom of the meniscus.
