Snow Water Equivalent Calculator

Convert snow depth to an approximate liquid-water depth without assuming one universal snow density.

Snow depth

Depth unit

Snow : liquid ratio

—Liquid-water depth

—Millimeters water

—Water depth as % of snow depth

—Ratio used

Snow density varies widely. This tool does not guess a universal snow-to-liquid ratio; use a measured or locally appropriate ratio when available.
