Q: What is a kilogram per gallon?

Kilogram per Gallon (kg/gal) measures density. A mathematically valid way to express liquid density in kilograms per US gallon. It is classified as a mixed metric/US customary density unit.

Q: What is a kilogram per cubic foot?

Kilogram per Cubic foot (kg/ft3) measures density. A mathematically valid way to express density in kilograms per cubic foot. It is classified as a mixed metric/US customary density unit.

About Converting Kilograms per Gallon to Kilograms per Cubic foot

Kilogram per Gallon and Kilogram 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

kilograms per cubic foot = kilograms per gallon × 7.48051948052

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 kilogram per cubic foot equals 35.3146667215 base units, so dividing one by the other gives the direct kilogram per gallon-to-kilogram per cubic foot factor of 7.48051948052.

Simple example

1 kg/gal × 7.480519481 = 7.480519481 kg/ft3

1 kilogram per gallon = 7.480519481 kilograms per cubic foot.

Real-world example

1,000 kg/gal × 7.480519481 = 7,480.519481 kg/ft3

1,000 kilograms per gallon = 7,480.519481 kilograms per cubic foot.
