About Converting Slugs per Imperial gallon to Pounds per Cubic Millimeter
Slug per Imperial gallon and Pound per Cubic Millimeter 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
pounds per cubic millimeter = slugs per imperial gallon × 0.00000707730127569
This factor comes from each unit's defined relationship to the category's base unit: 1 slug per imperial gallon equals 3210.20985885 base units, and 1 pound per cubic millimeter equals 453592370 base units, so dividing one by the other gives the direct slug per imperial gallon-to-pound per cubic millimeter factor of 0.00000707730127569.
Simple example
1 slug/imp gal × 0.000007077301276 = 0.0000070773 lb/mm3
1 slug per imperial gallon = 0.0000070773 pounds per cubic millimeter.
Real-world example
1,000 slug/imp gal × 0.000007077301276 = 0.0070773013 lb/mm3
1,000 slugs per imperial gallon = 0.0070773013 pounds per cubic millimeter.
