]> gistUOM The gist Unit of Measure Ontology Created with e6Tools Graphical OWL Editor Used for tempreature conversion because Celicus and Fehrenheit have non zero zero bases. It's the kelvin temperature of zero in the other temperature scale Currencies are rounded to specified precision used to convert from one unit of measure to another if they both have the same zero base. Note this is the conversion factor to multiply a unit by to get to the base. So the conversion factor for inch would be 0.0254. You divide by the convertToBase number to get from a base unit to another. Which unit of measure are you using. All measures are in some uom, even if we don't know what it is initially Second unit in the ratio unit of measure (Duration (time) in "speed"). Fiirst term in a ratio unit of measure. (Distance in the ratio unit "speed"). {Class.Description} {Class.Description} {Class.Description} {Class.Description} {Class.Description} {Class.Description} {Class.Description} {Class.Description} {Class.Description} This is a ratio class where the numerator and denominator are of the same unit of measure. This would have to be enforced as a SWRL rule. Note there are two conventions multiple by 100 or not (ie 50/100 could be .5 or 50) we are going with the .5 convention, despite the name, as it involves less additional conversion in its use. {Class.Description} {Class.Description} {Class.Description} {Class.Description} {Class.Description} {Class.Description} {Class.Description} {Class.Description} {Class.Description} {Class.Description} {Class.Description} {Class.Description} {Class.Description} {Class.Description} {Class.Description} 1.000 1.000 1.000 0 1.000 1.000 1.000 1.000 1.000 1.000 1.000 1.000
