iLOG supports the following unit systems:

  • Imperial (US CUstomary) units: lb, ft, in
  • Metric (Asia) units: kg, m, cm
  • Metric (US) units: kN, m, cm


There is no global unit system in iLOG. Instead, unit system is defined for each project when creating the project and it can be edited at any time (see more). Changing unit system, will affect the depth units shown in the borehole log.
