Darcy To Nanodarcys Converter
Reverse Conversion
How This Converter Works
Convert between Darcy (D) and Nanodarcys (nD). Select either direction to convert directly.
Formula or rule
Nanodarcys = Darcy * 1000000000; Darcy = Nanodarcys / 1000000000
Example
- Input
- 1 D
- Calculation
- 1 * 1000000000 = 1000000000
- Result
- 1000000000 nD
Notes
Intrinsic porous-media permeability is an area quantity. The Darcy flow definition uses 1 cm³/s, 1 cP, 1 cm length, 1 cm² area, and 1 atm pressure difference; k = qμL/(AΔp) gives 1 D = 9.869232667… × 10⁻¹³ m² (usually rounded to 9.869233 × 10⁻¹³ m²). Darcy prefixes use exact SI powers of ten. Hydraulic conductivity is not interchangeable because it also depends on fluid properties.
