When 2.5 centimeters of rain freezes what amount of snow does it make?

It is estimated that about 1 ft of snow is equal to 1 inch of rain.

Converting inch to cm

1 inch=2.54 cm

Thus, 1 cm=0.393 inch

2.5 cm of rain will be 0.984 inch

now 1 inch of rain is equal to 1 ft of snow, thus, 0.983 inch of rain will be:

0.983 inch of rain=0.983 ft of snow.

Converting ft to cm:

1 ft = 30.48 cm

Thus,

0.983 ft = 29.96 cm

Thus, 2.5 cm of rain = 29.96 cm of snow.
