About Converting Kilograms per Cubic foot to Kilograms per Gallon
Kilogram per Cubic foot and Kilogram per Gallon 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 Cubic foot is most often used for can be used to express the density of construction and bulk materials such as insulation, soil, or aggregate — in practice, pounds per cubic foot (us) or tons per cubic yard are the units more commonly seen in us construction references.
Formula
kilograms per gallon = kilograms per cubic foot × 0.133680555556
This factor comes from each unit's defined relationship to the category's base unit: 1 kilogram per cubic foot equals 35.3146667215 base units, and 1 kilogram per gallon equals 264.172052358 base units, so dividing one by the other gives the direct kilogram per cubic foot-to-kilogram per gallon factor of 0.133680555556.
Simple example
1 kg/ft3 × 0.1336805556 = 0.1336805556 kg/gal
1 kilogram per cubic foot = 0.1336805556 kilograms per gallon.
Real-world example
1,000 kg/ft3 × 0.1336805556 = 133.6805556 kg/gal
1,000 kilograms per cubic foot = 133.6805556 kilograms per gallon.
