This line is called the meniscus.
A graduated cylinder is divided into ounces or milliliters.

To determine the volume of an irregular object using graduated cylinders, you fill a graduated cylinder with water right to the top, then submerge the object in the water. Measure the water that overflows using a second graduated cylinder, and read the water level in it in cc's or cubic inches. That is the object's volume.

Using a 10 ML graduated cylinder you can read 2 decimal places. This is also measuring volume.
In milliliters (mL)
You *don't* read the line where the fluid meets the glass. You look past it, to the middle of the downward curve in the fluid, the "meniscus" and read from that.
You should read a graduated cylinder at eye level. See the related link for rules regarding menisci.
This line is called the meniscus.
When measuring with a graduated cylinder, you pour the liquid into the cylinder to a precise level. Read the measurement at the bottom of the meniscus, which is the curved surface of the liquid. Be sure to read the measurement at eye level for accuracy.
The "bottom of a curved line" made by the liquid in a graduated cylinder could be called the "measuring line" or "reference line" in the application of that piece of labratory equipment. The curved surface of the liquid itself is called the meniscus, and we look to the bottom of the meniscus to make our reading as to the volume of the liquid in the graduated cylinder. The liquid in the cylinder "grabs" the sides of the cylinder and "pulls itself up" just a bit, and that creates the curve in the surface of the liquid. And that curve, the meniscus (which is from the Greek word for crescent), leaves us with a problem: where do we "read" the volume marked off by the graduations along the side of the cylinder? And the answer is, "At the bottom of the meniscus."

To read the volume of water in a graduated cylinder, make sure your eye is level with the meniscus (the curved surface of the water). Read the volume at the bottom of the meniscus to get an accurate measurement. Ensure the graduated cylinder is on a flat surface to prevent parallax errors.
Use the water displacement method. You need a graduated cylinder and some water. Fill the graduated cylinder with enough water so that when you place the rock in the graduated cylinder it will cover the rock. Read the meniscus (the slightly curved line of the water) at eye level. Record your measurement of the water in the graduated cylinder (in mL). Place the rock in the graduated cylinder and record your new measurement of the water line, again at eye level. Subtract the original measurement from the new one to get the volume of the rock.
