Enter the snowfall in inches and the liquid equivalent in inches into the calculator to determine the snow to liquid ratio. This ratio helps in understanding the density of the snow.

Snow To Liquid Ratio Formula

The following formula is used to calculate the snow to liquid ratio.

SLR = S / L

Variables:

  • SLR is the snow to liquid ratio
  • S is the snowfall in inches
  • L is the liquid equivalent in inches

To calculate the snow to liquid ratio, divide the snowfall in inches by the liquid equivalent in inches.

What is a Snow To Liquid Ratio?

The snow to liquid ratio (SLR) is a measure used to describe the density of snow. It represents the depth of snow that falls compared to the equivalent amount of liquid water. A common average ratio is 10:1, meaning 10 inches of snow melts down to 1 inch of water. However, this ratio can vary significantly depending on the temperature and moisture content of the snow, ranging from light and fluffy snow to wet and heavy snow.

How to Calculate Snow To Liquid Ratio?

The following steps outline how to calculate the Snow To Liquid Ratio.


  1. First, measure the total snowfall (S) in inches.
  2. Next, measure the liquid equivalent (L) in inches. This is typically done by melting the collected snow and measuring the depth of the water.
  3. Use the formula SLR = S / L to calculate the snow to liquid ratio.
  4. Finally, enter the measurements into the calculator to verify the ratio.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Snowfall (S) = 8 inches

Liquid Equivalent (L) = 0.5 inches
