How to Convert Metre per Second to Gallon per Day per Square Foot
- 1 m/s = 2120462.215 gpd/ft²
- 1 gpd/ft² = 4.715952932 × 10⁻⁷ m/s
- Example: convert 15 m/s to gpd/ft²: 15 m/s = 15 × 2120462.215 gpd/ft² = 31806933.22 gpd/ft²
Formula
gpd/ft² = m/s × 2120462.21495
Derivation from SI units:
- Hydraulic conductivity K = discharge per unit area per unit hydraulic gradient, in m/s.
- 1 gpd/ft² = 0.003785411784 m³ ÷ 86,400 s ÷ 0.09290304 m².
Both units are defined exactly, so the factor is exact. Metre per Second definition: metre per second; Gallon per Day per Square Foot definition: US gallon per day per square foot.
Worked examples
- A reading of 0.0000001 m/s converts to 0.2120462215 gpd/ft².
0.0000001 m/s × 2120462.215 = 0.2120462215 gpd/ft² - A value of 0.0001 m/s is 212.0462215 gpd/ft².
0.0001 m/s × 2120462.215 = 212.0462215 gpd/ft²

Where it's used
Metres per Second are used for darcy’s law and seepage analysis, while US gallons per day per square foot appear in older USGS and well-driller reports. Both measure hydraulic conductivity (coefficient of permeability k), so the conversion is a fixed factor.
