Start with the units in your recipe. Choose an ingredient only when moving between volume and weight.
Volume conversions
Cups and fluid ounces
Convert in either direction with the cup and fluid-ounce standards named.
Cups and milliliters
Move between recipe cups and a jug’s metric markings.
Cups and tablespoons
Turn a smaller cup quantity into a measuring-spoon quantity.
Tablespoons and teaspoons
Work with smaller quantities while keeping the spoon definitions clear.
Weight and ingredient conversions
Ounces and grams
A direct mass conversion. Use ounces by weight, not fluid ounces.
Cups and ingredient weights
Choose flour, sugar, butter, or whole milk to estimate weight from a named source portion.
Not sure which tool fits?
If the recipe says fl oz, start with volume. If it gives oz by weight, start with mass. If you need a scale weight for a cup of food, use the ingredient tool.
The unit guide explains the distinction; the cup-size guide helps you choose a standard.
