The instrument commonly used to measure the external diameter of a glass rod is a caliper, specifically a vernier caliper or a digital caliper. These tools allow for precise measurements by fitting around the rod and providing a reading on a scale or digital display. For larger diameters, an inside micrometer or a dial gauge can also be used.
Because its true diameter would be inaccurate because of the curvature of the glass.
It depends on the size of it.
Circumference = pi*diameter = 17.3 centimetres.
The volume of a glass cylinder with an inside diameter of 6.0 cm and height of 28 cm is 791.68 cubic cm.

No, the external bulb of a thermometer is typically made of glass to hold the mercury inside. Mercury is usually contained within the glass bulb to measure temperature accurately without exposing the user to the toxic substance.
The average diameter of the mouth of a 500 ml glass beaker is around 8-9 cm.
Top diameter at 1.75" and the height at 2.25"
It depends on the size of it.
A Campbell-Stokes sunshine recorder is commonly used for this purpose. It consists of a glass sphere about 140mm diameter, and which, by focusing the Sun's rays, burns a track in a curved slip of paper. This burn mark is read manually. Nowadays replaced by electronic equipments that do the same task automatically, and with repeatable results.
Circumference = pi*diameter = 17.3 centimetres.
The instrument used to measure temperature is called a thermometer. It typically contains a liquid, such as mercury or alcohol, that expands and rises in a glass tube as the temperature increases. Thermometers can be used in various settings, including weather stations, homes, and laboratories, to provide accurate readings of ambient temperature.
The eardrum, because it is recessed and less affected by external temperatures, is an extremely accurate point to measure body temperature. It is actually quicker than using a traditional glass medical thermometer. with the risk of the glass tube breaking.

Only the diameter is measured in milimetres.
