Weight of Snow

The Weight of Snow calculator computes the approximate weight (mass) of snow on a given area (A) (e.g. roof) based on the depth (d) and type (sT) of snow.  

INSTRUCTIONS:  Choose units and enter the following:

• (A) Area in Snow
• (d) Depth of Snow
• (sT) Type of Snow (Choose one: See Table) 

Weight of Snow (W): The calculator returns the weight of snow in kilograms.  However this can be automatically converted to other weight or mass units (e.g. pounds or tons) via the pull-down menu. 

The Math / Science

The Weight of Snow calculator takes in to account the area covered, the depth of the snow, and the type of snow (based on standard snow types).  It computes the volume of snow and then uses the mean density of the specified type of snow (see table) to compute the mass.

      M = A • d • ρ

where:

• M = mass or weight of snow
• A = area of snow
• d = depth of snow
• ρ = density of snow
