Question

if the depth of water in the rainguage is 1cm, it indicates the rainfall?​

Answer 1

Answer:

Suppose you have a vessel, preferably cylindrical, and kept on a horizontal base, the height up to which the rain is collected measures the rainfall. If it is one Cm, it is one cm rainfall. To measure accurately, a measuring glass of 1/10 th base area of the rain gauge will be used. So 1 cm will go up to a height of 10 Cm but will be calibrated as only 1 Cm. One cm of measuring glass will then refer to one mm only and one mm will refer to 1/10th of a mm. Rainfall will therefore will be measured correct up to one-tenth of a mm.
