Soil bulk dry density calculator

Calculate wet bulk density and dry density with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use wet bulk density and dry density to compare changes to your inputs. The method and limits below explain the scope.

Calculation method

Calculation method

Wet bulk density (g/cm³)

Bulk density=wet mass/volume; dry density=bulk density/(1+water content fraction).

Dry density (g/cm³)

Bulk density=wet mass/volume; dry density=bulk density/(1+water content fraction).

Symbols and units

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; Bulk density=wet mass/volume; dry density=bulk density/(1+water content fraction). 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.
