When selecting the Units of Measure to be used in the AFS Pro 600 and AFS Pro 700 (Toolbox > Operator Setup), what is the difference between "Imperial" and "USA"?
"USA" displays standard "English" units of measure (acres, gallons, pints, quarts, bushels, pounds, ounces, tons, etc.)
"Imperial" is very similar to "USA", except that an Imperial Gallon contains 5 quarts, rather than a "USA Gallon", which contains 4 quarts.
"Metric" displays standard metric units of measure (hectares, liters, milliliters, kilograms, grams, metric tonnes, etc.)
Note that when "Metric" is selected, user-defined windows (Run screen windows) displaying any bushel-related values ("Bushels, Dry", "Bushels, Wet", "Flow, Dry bu", etc) are not available, as the "bushel" is not a valid unit of measure in the Metric system of measurement.
