The density of water is documented at given temperatures to a very high degree of reliability. With this knowledge, an analytical balance and a thermometer, the mass each implement contains or displaces can be translated into a volume. Compare the measured volume to the written volume for accuracy.
As an aside, in order of decreasing accuracy they are: pipette, graduated cylinder then beaker.
