Also, notice that the drop down boxes contain further unit breakdown options.
The following list details the different types of Measurement fields and their contained units:
Length (small) - mm/cm/in
Length (medium) - m/ft
Pressure - kPa/psi
Area - mm2/cm2/in2
Weight - kg/lbs
Force - KdaN/lbf
Density - kg/m3 / lb/gal
Flow - m3/min / gal/min
Temperature - C/F
Volume (small) - cm3/ml/in3/oz US
Volume (medium) - m3/L/ft3/gal US/bbl US
Volume (large) - 10m3/ML/Mcf
All Measurement field units are available to be chosen in a view. Values will be automatically converted to the other units available for the measurement field type.
