We're considered to be quite high up the side of our hill, (Mt. Egmont,) 750 ft., and we get 6 ft. of rain annually whether we need it or not.
And we've had snow only about half-a-dozen times in the last fifty years.

With those two factors, that's why we can grow grass all year round, (albeit a bit more slowly over winter,) and can run dairy cows outside all year round too.
Yep; God's Own Country alright!
They say that 1" of snow = see below.

That is usually common knowledge for meteorologists.
They also have that info here: What is the formula for switching rain to snow in inches? - Yahoo Answers

The general formula is as follows.

About 1 inch of rain = 10 inches of snow.

However, there are various forms of snow. Some is low density while other snow is high density. This will help you in general.

If it is a dry, cold snow and the temperature is BELOW 12ºF than the snow is most likely LOW DENSITY and with the following formula.

12 inches of snow = 1 inch of liquid rain.

If the snow falls when the temperature is between 12ºF and 24ºF then the average of 10 to 1 - 10 incoes = 1 inch of rain - can be followed in general.

If snow is falling and the temperature is between 24ºF and 28ºF the snow is more dense usually and the following forumla is used in general. 7 inches of snow = 1 inch of rain.

If the temperature is above 28ºF and lower than 31ºF than it is usually a heavy - wet and dense snowfall with some melting taking place especially in heavy snows. Then the formula wildely varies but usually 5 inches to 1 inch - 5 inches of snow = 1 inch of rainfall - is used.
