About Converting Pounds per Fluid ounce to Grams per Cup
Pound per Fluid ounce 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 = pounds per fluid ounce × 3628.73896
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per fluid ounce equals 15337.7826966 base units, and 1 gram per cup equals 4.22675283773 base units, so dividing one by the other gives the direct pound per fluid ounce-to-gram per cup factor of 3628.73896.
Simple example
1 lb/fl oz × 3628.73896 = 3,628.73896 g/cup
