About Converting Troy ounces per Cup to Grams per Cup
Troy ounce per Cup and Gram per Cup both measure density — mass per unit volume — a property used to identify materials, check manufacturing quality, and predict whether something floats or sinks. As a fixed reference point, water has a density of exactly 1000 kg/m³ (1 g/cm³, 1 g/mL) at its temperature of maximum density, which is why many density figures in science and engineering are quoted relative to water. Both are mass per volume density units.
Formula
grams per cup = troy ounces per cup × 31.1034768
This factor comes from each unit's defined relationship to the category's base unit: 1 troy ounce per cup equals 131.466708828 base units, and 1 gram per cup equals 4.22675283773 base units, so dividing one by the other gives the direct troy ounce per cup-to-gram per cup factor of 31.1034768.
Simple example
1 oz t/cup × 31.1034768 = 31.1034768 g/cup
