Video transcript

Approximately 4 inches of snow is equivalent to 0.4 inches of water, assuming an average snow-to-water ratio of 10:1. This conversion helps in understanding snowmelt and potential water accumulation.

Questions and answers

  1. What is the snow-to-water ratio?

    The snow-to-water ratio is the average amount of snow that melts down to a specific depth of water, commonly around 10:1, meaning 10 inches of snow equals about 1 inch of water.

  2. How do you convert inches of snow to inches of water?

    You can convert inches of snow to inches of water by dividing the snow depth by the snow-to-water ratio, often 10, so 4 inches of snow would equal approximately 0.4 inches of water.

  3. Does the snow-to-water ratio vary?

    Yes, the snow-to-water ratio varies depending on snow density, temperature, and moisture content, with ratios commonly ranging from 8:1 to 15:1.
