This mark is the indication of the exact volume of the flask at a given temperature (generally at 20 0C).

NO!!! Use a 'Measuring Cylinder' for an exact volume of liquid.

They both do something :)

Use a calibrated flask.
The unit that the rain gauge and measuring flask measured is centimeter
They are calibrated to water.
It is a measuring tape which is calibrated in metric units.
There are various instruments that can be used, even a kitchen jug with calibrated marks. Others include:BeakerErlenmeyer FlaskFlow meterGraduated CylinderGravimetric scales (if the specific gravity of the liquid is known)Measuring cupPipetteVolumetric flask
A measuring flask.
Strictly, it's measuring weight, but most are calibrated to give mass.

Volumetric flask, also known as measuring flask or graduated flask, is a kind of glassware which is used for accurate dilutions and preparation of standard solutions. Volumetric flasks are usually pear-shaped with a graduation mark on the neck. The mark indicates the volume when the solution reaches there. Volumetric flasks are various in size, but they come in standard size, 10.00 ml, 25.00 ml, 50.00 ml, 100.0 ml, 250.0 ml, 500.0 ml, etc.
Solutions with known molarity are usually made in volumetric flasks that are calibrated and certificated. So for example I would weigh 58.5 g of NaCl and wash with water into a 1 liter volumetric flask and make exactly to the calibrated mark on the flask neck so I would have exactly 1 liter. My molarity would be exactly 1.00 moles NaCl per liter. Similarly there are 100 ml, 250 ml, 500 ml and other calibrated volumetric flasks so the volume is always exactly known.
