You should always measure at the lowest part of the meniscus. The meniscus is a slight curvature at the top of a liquid in a container.

What is a meniscus is and how it is used to measure liquids?
A meniscus is the curve of a liquid. Like when you are filling a glass of water, if you continue to put water in the glass after it has reached the top, then the extra water will go above the glass in a curved shape. When you are measuring liquids in for example a graduated cylinder, you would take the measurement from the bottom of the meniscus. I hope this helps!
Where do you read the meniscus?
Take the measurement at the bottom of the meniscus, not where it arches up against the sides.
How is a meniscus used in measuring?
As the diameter of the container decreases, the meniscus becomes more pronounced. The meniscus may be convex (curving upward) or concave (curving downward). Most of the time you will find that the meniscus is concave. The most notable exception is the meniscus that forms from mercury. When taking measurement readings it is important that the reading is done properly. The following rules must be adhered to: I. Read the meniscus at eye level. Do not read the meniscus from above or below eye level. Significant measurement errors may occur II. Read the bottom of a concave meniscus and the top of a convex meniscus.
What is a meniscus why it necessary to know about it when measuring liquids?
The meniscus is the concave line of liquid that forms in a graduated cylinder (measuring volume) due to that liquid's adhesion (the tendency to want to stick to other things). When measuring a liquid's volume in a graduated cylinder, you read the volume from the bottom of the meniscus. Therefore, the meniscus does not measure anything, it is where you measure a liquid's volume from.
What meniscus is being read if you measuring the volume of dark colored liquids?
1.read the bottom of the curve 2. you must read the meniscus at eye level

When you are measuring the volume of water in a graduated cylinder do you look at the top of the meniscus or the bottom of the meniscus?
You measure from the bottom of the meniscus. The top of the meniscus can vary wildly depending on the diameter of the tube, or the air pressure, or room temperature.
Why do we use the lower meniscus to read the clear liquid and upper meniscus to read the colored liquid?
If the colored liquid is opaque (you can't see through it) you can't see the bottom of the meniscus. If the liquid is like mercury, you can't see through it but it doesn't make any difference because the meniscus is reverse from that of water. You read the top.
Would a graduated cylinder be read at the middle of a meniscus?
The answer depends on the liquid, or more specifically, how the surface tension in the liquid affects the meniscus. It should be the top of the meniscus for liquids such as mercury but the bottom for liquids such as water or alcohol.
How is the meniscus used in measuring the volume of liquids?
AnswerA meniscus is when the attractive force between the liquid and the container is greater than the attraction between the individual liquid molecules. This causes the liquid to "stick" to the side of the container, creating a curve. The volume must be read at the bottom of the meniscus.

When reading a graduated cylinder you look at?
When you read a scale on the side of a container with a meniscus, such as a graduated cylinder or volumetric flask, it's important that the measurement accounts for the ... For mercury, take the measurement from the top of the meniscus. ...
Did you measure at the top of the meniscus or the bottom?
You measure at the bottom of the meniscus.
How do you read the correct measurement from the measuring apparatus?
If you are talking about a liquid measuring cup (or a breaker) you must get eye level with the cup and where the line of water (meniscus) meats the line on the cup you have the correct amount.
