| Amount | The multiplier that converts the FromUOM to the ToUOM. It is intended to represent a ratio. It applies to simple conversions. A separate attribute is used to define a conversion formula for more complex conversions (e.g. between degrees Faharenheit and degress Celcius) | MO_UOM_CVN | Quantity | DECIMAL(9,3) | |
| ConversionRuleDescription | A short text representation of the formula used to convert between two distinct units of measure. For example to convert degrees celcius to degrees Fahrenheit use F=(C * 9/5)+32. It requires a little more information that a simple ratio. | DE_CVN_RUL | DescriptionShort | varchar(255) | |
