The density of snow is very different, depending on its age. It ranges between 0.03 g/cm3 and 0.8 g/cm3. Therefore the prescribed values are given just for orientation.
|Precipitation||Units for rainfall and volume spread|
|Amount of rain||Volume of precipitation on an area|
|Pressure||Several units for pressure|
At first choose the kind of precipitation for which you want to calculate the equivalents.
For some kinds the density is already given. You may also choose "?"
and type your own values for the density.
Next, either type the height of the precipitation, the volume per area, the mass per area or the pressure on the ground into the field behind which you find the correct unit. Click on any empty space in the window or the "calculate" button. Read the result in the other fields.
In order to calculate the equivalent amount of another kind of precipitation choose this kind from the pull-down-menu. The equivalent height and the volume per area are newly calculated. The mass per area and the pressure stay the same.
Move the mouse over a unit or click on it to read its full name. Use the "reset" button to reset your calculation.
Example: There have been 30 cm of fresh snow. What is the pressure of this snow
on a roof? At first choose "Fresh snow" from the pull-down-menu.
Type "30" into the field behind which "cm" is written.
Click on any empty space in the window or the "calculate" button.
The pressure of the snow is 294.2 Pascal
What is the equivalent amount of rain to this snow? Choose "Rain" in the pull-down-menu. The height and the volume per area are newly calculated. The amount of snow corresponds to 30 mm of rain.
