it doesnt matter, as long as you are consistent

Explanation:

To accurately measure the volume of a liquid in a graduated - cylinder, one should look straight at the meniscus (at eye - level). Looking up or down can introduce parallax errors. However, if the same non - ideal viewing angle is used consistently in a series of measurements, relative differences can still be accurately determined.
