Dairy & liquids
Convert butter, water, milk, olive oil, yogurt, sour cream, and cream cheese with ingredient-specific references.
This group brings together water, milk, olive oil, butter, yogurt, sour cream, and cream cheese. They share common measuring tasks, but they do not share one universal density or one preparation state.
Identify the kind of measurement
Millilitres and cups describe volume. Grams and ounces of mass describe weight as used by a kitchen scale. Fluid ounces and ounces of mass are different units; read the full unit before choosing a conversion.
A volume-to-volume conversion uses the stated unit definition. A volume-to-mass conversion also needs the selected ingredient reference. Do not assume that every liquid has the same relationship as water.
Check the product and form
A reference for butter should be read with its stated form. A solid package marking, a measured portion, and melted butter may describe different ways of establishing the original amount.
Keep yogurt, sour cream, and cream cheese as separate ingredients. If the recipe identifies a particular style or preparation, preserve it in the row note. A broad ingredient name does not establish every brand or variation.
Use package weights when available
When a package or recipe supplies the weight you need, use that weight directly. A half portion of a known 200 g amount is 100 g without a cup conversion.
If the recipe instead gives “half a tub,” identify the tub size before treating it as a fixed mass. Retain package information in the note so a later shopping list does not combine unequal packages as though they were identical.
Keep formula water explicit
In a basic baker’s formula, the whole mass of milk, butter, or yogurt should not be counted as water. BatchLadle’s hydration figure uses identified water and the declared water contribution of a starter.
Mixed ingredients remain separate formula rows. A more detailed water-composition calculation would require additional composition data and a stated method; an ingredient density alone does not supply that information.
