This entry keeps an olive-oil source recipe measure and a separate FAO/INFOODS density record. It does not use water or a generic cooking-oil value to fill a missing relationship.
Keep the olive-oil scope
The FAO/INFOODS entry reports olive-oil density with an underlying bibliography reference. The consulted record does not provide a measurement temperature, so that missing condition remains a limitation.
The King Arthur record uses a source-cup relationship without an established millilitre definition. It remains usable as that source’s own recipe measure.
Distinguish volume ounces from mass ounces
If the original recipe says fluid ounces, it describes volume. An ounce read as a mass unit on a scale describes a different quantity. Choose the appropriate unit before requesting a conversion.
A direct change between volume units needs a defined unit system. Moving from that volume to grams additionally needs the selected olive-oil reference.
Keep the recipe’s oil choice
Do not attach this reference to another oil solely because both ingredients are liquid. Keep the named oil and any product preference in the ingredient note.
When the recipe already gives grams, scale the weight directly. In a baker’s formula, oil remains a separate ingredient and does not add its entire mass to identified water.
