Gallons per day per ft² to meters per second
Type a value in gpd/ft² to get it in m/s instantly.
4.716×10⁻⁹m/s
That's 47× as permeable as clay, while silt is 21× more permeable.
Convert the other way: m/s to gpd/ft²
What it means
How fast does water pass?
For water at about 20 °C. Ranges for each soil span a factor of 100 or more; the darcy unit applies to water at 20 °C.
The math
How to convert gpd/ft² to m/s
To convert gallons per day per ft² to meters per second, multiply by 4.716×10⁻⁷.
Example: 0.01 gpd/ft² × 4.716×10⁻⁷ = 4.716×10⁻⁹ m/s.
In the other direction, 1 m/s = 2,120,460 gpd/ft².
