You are watching: 1 inch of snow equals how much rain
Perform the baseline rain-to-snow conversion. The baseline proportion of rain to snow is 1 inch of rain equals 10 customs of snow. For example, to calculation the snowfall equivalent of 3 inches of rain, main point 3 by 10 to obtain 30 inches of snow as the baseline conversion. This conversion applies for eye falling in ~ temperatures near freezing, in between 28 and 34 levels Fahrenheit.
Find the temperature in the place for which you"d prefer to do the conversion. You can track under this details via the national Weather Service, for example, or any number of other meteorological sources, such together the Weather Channel. In general, chillier temperatures make snow fall less densely and lower the rain-to-snow ratio, result in much more inches of eye per customs of rain.
Adjust your conversion to account because that temperature if the outside temperature is much less than or equal to 27 degrees Fahrenheit. To calculate rain to eye for temperatures in between 20 and 27 levels Fahrenheit, main point rainfall through 15 rather of 10. For temperatures in between 15 and also 19 levels Fahrenheit, multiply rainfall by 20. In between 10 and also 14, multiply by 30; in between 0 and also 9, main point by 40; between -20 and -1, main point by 50, and also between -40 and also -21, main point by 100. Because that example, to calculation the snowfall tantamount of 3 customs of rain in ~ 5 levels Fahrenheit, main point 3 by 40 to attain 120 inches of snow. Therefore, if 3 customs of rain room expected however the temperature drops all of sudden to 5 degrees Fahrenheit, 120 customs of snow will certainly fall.
Perform the calculations in turning back to calculate snow to rain. Because that example, because that 8 customs of eye falling in ~ a temperature that 20 levels Fahrenheit, divide 8 by 15, due to the fact that the conversion aspect for 20 degrees is 15. The an outcome is about 0.53 inch of rain. Therefore, 8 inch of eye that fell at 20 levels Fahrenheit will melt down to about 0.53 inches of rain.
numerous factors impact snow density apart indigenous ambient temperature. Wind, because that example, deserve to compact snow and cause it come fall more densely, lowering the rain-to-snow ratio.

many factors impact snow thickness apart native ambient temperature. Wind, for example, deserve to compact snow and also cause it come fall much more densely, lowering the rain-to-snow ratio.
