Centimeters of water to millimeters of water

300mm SWE
That's 3× as deep as a good ski base, while a deep mountain pack is 1.33× deeper. On a 10 m by 10 m roof that is about 30,000 liters of water.
What it means
How much water is that?
Snow density changes as a pack settles, so a measured depth converts differently on the day it falls and a week later.
The math
How to convert cm SWE to mm SWE
To convert centimeters of water to millimeters of water, multiply by 10.
Example: 30 cm SWE × 10 = 300 mm SWE.
In the other direction, 1 mm SWE = 0.1 cm SWE.
The table below is for Cold powder (5% water).
