Snowfall Water Equivalent Calculator

The snow water equivalent (SWE) is a measure used in meteorology and hydrology to quantify the amount of liquid water contained within a volume of snow. This metric is crucial for understanding the potential impact of snow on water resources, infrastructure, and outdoor activities such as skiing and snowboarding.

The SWE is calculated by multiplying the depth of the snow (in inches) by its density (in pounds per cubic foot). The formula provides a standardized way to compare different types of snow and their impacts. For example, fluffy powder snow has a lower density compared to compacted or wet snow, resulting in a lower SWE for the same depth.
