Enter the total amount of rain precipitation in inches and the temperature to calculate the equivalent amount of snow.
Rain to Snow Formula
The following formula is used to calculate the amount of snow in inches from 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 this 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.
FAQ
One inch of rain will equal between 5-7 inches of snow depending on the temperature
