Convertible Units
Summary: That is, I can say that a Property is of type Volume. Any Volume from any System can be used.
When doing data entry, typically the display should be showing a consistent system. So if I am showing Metric, a Volume Property will allow me to choose from Liters, Milliliters, etc; if English, it will allow me to choose from Cups, Quarts, Tablespoons, etc.
