Centimetre per Hour (cm/h)
Centimetres per hour express infiltration rates and the saturated conductivity of agricultural soils: about 2.5 cm/h for a sandy loam and under 0.1 cm/h for clay.
Symbol: cm/h
Quantity: hydraulic conductivity (coefficient of permeability k)
SI relation: 1 cm/h = 0.000002777777777778 m/s (exact)
Derivation: 1 cm/h = 0.01/3600 m/s.
Exact: yes, by definition
Typical uses
- Infiltration capacity and Horton’s equation
- Soil permeability classes (USDA)
- Irrigation design
