WebThe phi scale is a useful, logarithmic-based modification of the Udden-Wentworth scale. Grain-size diameters in millimetres are converted to phi units using the conversion formula: phi (ϕ) = - log 2S, where ϕ is size expressed in phi units and S is the grain size in millimetres. Phi values for grains coarser than one millimetre are negative ... WebMay 13, 2012 · Another noted that in Greek the letter PHI is indeed pronounced PHEE.
