The above values have been provided with both imperial and metric units. As with all calculations care must be taken to keep consistent units throughout. A guide to Soil Types has been provided by StructX and additional information has been provided below.

Notation

ρ = bulk density (the ratio of the total mass to the total volume), ib/ft³ or kg/m³
C_u = cohesian, psi or kPa
