Keeping Flour Weight Separate From Volume

Flour weight and cup volume answer different measuring questions. A reliable converter should refuse to bridge them without suitable density information, even when producing a number would look more convenient.

A baker has a flour weight of 120 g and wants to turn it into cups.

Try volume, then a compatible weight

1. Enter 120 in Convert a quantity. Choose g as From and US cup as To.
2. Select Convert and read the error message.
3. Change To to oz to request a supported mass conversion.

One request is refused for a reason

The gram-to-cup request is rejected. The gram-to-ounce request displays approximately 4.23288 oz.

Grams to ounces stays within weight. Grams to cups needs an ingredient-specific relationship that also depends on how flour is measured; the converter does not invent one.

Weigh the flour if the source recipe specifies grams.
