Notation and Units

Metric and Imperial Units

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.


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