About Converting Kilograms per Gallon to Pounds per Cubic foot
Kilogram per Gallon and Pound per Cubic foot 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. Kilogram per Gallon is most often used for can be used to express liquid density such as fuel or industrial liquids in kilograms per gallon — in practice, kilograms per liter (metric) and pounds per gallon (us customary) are the specific pairings more commonly seen in fuel and liquid-density references.
Formula
pounds per cubic foot = kilograms per gallon × 16.4917224699
This factor comes from each unit's defined relationship to the category's base unit: 1 kilogram per gallon equals 264.172052358 base units, and 1 pound per cubic foot equals 16.018463374 base units, so dividing one by the other gives the direct kilogram per gallon-to-pound per cubic foot factor of 16.4917224699.
Simple example
1 kg/gal × 16.49172247 = 16.49172247 lb/ft3
1 kilogram per gallon = 16.49172247 pounds per cubic foot.
Real-world example
1,000 kg/gal × 16.49172247 = 16,491.72247 lb/ft3
1,000 kilograms per gallon = 16,491.72247 pounds per cubic foot.
