Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Measured uniform snow only. Not design snow load; drift, ice, roof shape and structural capacity are excluded.
Example Calculation
- Snow depth: 0.3 m
- Bulk snow density: 200 kg/m³
- Horizontal area: 100 m²
Snow depth = 0.3 m; Bulk snow density = 200 kg/m³; Horizontal area = 100 m². Primary result: 0.588399.
Frequently asked questions
How do I use this calculator?
Enter snow depth, bulk snow density, horizontal area. The result updates automatically. Use Reset to restore the example values.
What method does it use?
pressure=depth ×density ×g; total force=pressure ×area.. Measured uniform snow only. Not design snow load; drift, ice, roof shape and structural capacity are excluded.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
