a graduated cylinder is used to measure

They are cylindrical in nature like the graduated cylinders with their calibrations printed on the side. For water and most liquids, this is the bottom of the meniscus. what is a graduated cylinder used to measure, How you can Calibrate a Graduated Cylinder. The obvious answer to what a graduated cylinder measures is of course the volume of liquids. Graduated cylinders are thin glass tubes used to measure the volumes of liquids. This cylinder is a measuring container, made up of glass or resistive plastic materials with volume units marked on it, along its length. The markings are calibrated according to actual volume measurements, by manufacturers. The bottom of the meniscus in this case clearly lies between the 21 and 22 mL markings, meaning the liquid volume is certainly greater than 21 mL but less than 22 mL. In this case, the measurement interval marked by each line equals 1 (the numbered interval) divided by 5 (the count from one interval line to next), or: So, this sample graduated cylinder measures accurately to 0.2 ml. The smaller measurement is more accurate. Always read a graduated cylinder from the bottom of the meniscus.
