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 pound per cubic inch?

Pound per Cubic inch (lb/in3) measures density. A US customary density unit suited to describing dense materials in a small volume. It is classified as a US customary density unit.

About Converting Kilograms per Gallon to Pound per Cubic inches

Kilogram per Gallon and Pound 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. 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

pound per cubic inches = kilograms per gallon × 0.0095438208738

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 inch equals 27679.9047102 base units, so dividing one by the other gives the direct kilogram per gallon-to-pound per cubic inch factor of 0.0095438208738.

Simple example

1 kg/gal × 0.009543820874 = 0.0095438209 lb/in3

1 kilogram per gallon = 0.0095438209 pound per cubic inches.

Real-world example

1,000 kg/gal × 0.009543820874 = 9.543820874 lb/in3

1,000 kilograms per gallon = 9.543820874 pound per cubic inches.
