Bulk density (g/cm 3) = Dry soil weight (g) / Soil volume (cm 3) Bulk density is usually expressed in megagrams per cubic metre (Mg/m 3 ) but the numerically equivalent units of g/cm 3 and t/m 3 are also used (1 Mg/m 3 = 1 g/cm 3 = 1 t/m 3 ) (Cresswell and Hamilton, 2002).

Bulk density = Oven dry soil weight / volume of soil solids and pores Bulk density of mineral soils commonly ranges from 1.1 to 1.5 g/cm 3 in surface horizons. It increases with depth and tends to be high in sands and compacted pan horizons, and tends to be low in soils with abundant organic matter.

Unit weight of a soil mass is the ratio of the total weight of soil to the total volume of soil. Unit Weight, g, is usually determined in the laboratory by measuring the weight and volume of a relatively undisturbed soil sample obtained from a brass ring.Measuring unit weight of soil in the field may consist of a sand cone test, rubber balloon or nuclear densiometer.
