Inch per Hour (in/h)
Inches per hour describe infiltration, soil permeability classes and rainfall intensity in US practice; USDA soil surveys give saturated conductivity in in/h.
Symbol: in/h
Quantity: hydraulic conductivity (coefficient of permeability k)
SI relation: 1 in/h = 0.000007055555555556 m/s (exact)
Derivation: 1 in/h = 0.0254/3600 m/s.
Exact: yes, by definition
Typical uses
- USDA soil survey permeability classes
- US stormwater design rainfall intensity
- Turf and sports-field drainage
