About Converting Ounces per Cubic foot to Kilograms per Gallon
Ounce 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. Both are mass per volume density units.
Formula
kilograms per gallon = ounces per cubic foot × 0.00378978000109
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per cubic foot equals 1.00115396087 base units, and 1 kilogram per gallon equals 264.172052358 base units, so dividing one by the other gives the direct ounce per cubic foot-to-kilogram per gallon factor of 0.00378978000109.
Simple example
1 oz/ft3 × 0.003789780001 = 0.00378978 kg/gal
1 ounce per cubic foot = 0.00378978 kilograms per gallon.
Real-world example
1,000 oz/ft3 × 0.003789780001 = 3.789780001 kg/gal
1,000 ounces per cubic foot = 3.789780001 kilograms per gallon.

Understanding the 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.
Uses of the Kilogram per Gallon today
- 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
Kilogram per Gallon — sources
- Fuel and petroleum liquid-density references — Liquid density figures for fuels are typically reported in kg/L, kg/m³, or lb/gal rather than kg/gal.

What is a ounce per cubic foot?
Ounce per Cubic foot (oz/ft3) is a unit of density.
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.
Is the ounce per cubic foot to kilogram per gallon conversion exact?
