The absolute permeability is a property of the rock and is essentially the permeability measured with single phase or at 100% single phase saturation. The [[relative permeability]] is a dimensionless quantity whose magnitude is between 1.0 and 0, depending on the saturation ([[:file:fundamentals-of-fluid-flow_fig3.png|Figure 3]]). Relative permeabilities are measured in core (petrophysical) laboratories, and the results are reported versus the saturation. Some laboratories normalize relative permeability values with values different than the single phase or 100% saturation value, so some caution needs to be taken in interpreting and using reported data.
