Metres or centimetres.
Millimeters.
A ruler.
A ruler will measure anything smaller than a piece of paper (paper size is not given). If this is not meant by the question, more info is required.
On a ruler using the metric system, you would typically find units such as centimeters and millimeters. These units are used for measuring length and are based on powers of ten for easy conversion. The metric system is widely used in many countries around the world.
The answer depends on what characteristic you wish to measure: its mass, length, volume etc.
I would use a ruler (metric) but careful to only measure the inside. You could also wet the beaker and place it on a piece of paper (rim down). This will leave a wet ring that you can measure. But be sure only to measure the dry inner part of the ring.
