Rain to Snow Formula
The following formula is used to calculate the amount of snow in inches from the rain in inches.
S = R * 5 + T/16
- Where S is the amount of snow (inches)
- R is the amount of rain (inches)
- T is the temperature in F (if the temperature is less than 0, leave these blanks)
Rain to Snow Conversion
Converting rain to snow is the process of calculating the amount of snow that would fall from a given amount of rain precipitation if it was cold enough outside.
Rain to Snow Example
How to convert rain to snow?
- First, determine the expected amount of rain.
For this example, we will say the total amount of precipitation is expected to be 2inches of rain.
- Next, determine a theoretical temperature.
We will say that in theory, the temperature would be 30 F.
- Finally, calculate the snow.
We can calculate the amount of equivalent snow using the formula above so S = 2*(5+30/16) = 2 * (6.875) = 13.75″ of snow at that temperature.
One inch of rain will equal between 5-7 inches of snow depending on the temperature
