About Converting Pounds per Imperial gallon to Decigram per Cubic inches
Pound per Imperial gallon and Decigram per Cubic inch 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
decigram per cubic inches = pounds per imperial gallon × 16.3504180452
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per imperial gallon equals 99.7763726631 base units, and 1 decigram per cubic inch equals 6.10237440947 base units, so dividing one by the other gives the direct pound per imperial gallon-to-decigram per cubic inch factor of 16.3504180452.
