                                The density of an ingredient significantly affects its volume-to-weight conversion, which is why 100g of mayonnaise does not equal the same volume as 100g of water or flour. For most traditional mayonnaise varieties, 100g is approximately 0.43 to 0.47 U.S. cups, though this can vary slightly by brand.
