Calculation method
Calculation method
D10 (mm)
Interpolate log(diameter) linearly against percent passing; Cu=D60/D10, Cc=D30²/(D10D60).
D30 (mm)
Interpolate log(diameter) linearly against percent passing; Cu=D60/D10, Cc=D30²/(D10D60).
D60 (mm)
Interpolate log(diameter) linearly against percent passing; Cu=D60/D10, Cc=D30²/(D10D60).
Uniformity coefficient Cu
Interpolate log(diameter) linearly against percent passing; Cu=D60/D10, Cc=D30²/(D10D60).
Curvature coefficient Cc
Interpolate log(diameter) linearly against percent passing; Cu=D60/D10, Cc=D30²/(D10D60).

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Interpolate log(diameter) linearly against percent passing; Cu=D60/D10, Cc=D30²/(D10D60). Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
