It is important to read the fluid measurement at the meniscus level or horizontal center
of the fluid. Liquids curve up at the edge of the medicine cup, and reading the fluid level
at the edge of the cup is not accurate. Using the metric and household calibrations is not
an accurate reading of the meniscus.
