Understanding grams per cubic centimeter to ounces per US gallon Conversion
The gram per cubic centimeter (g/cm³) is the metric density unit used in science and material datasheets. The ounce per US gallon (oz/gal) pairs the avoirdupois ounce with the US liquid gallon (3.785411784 liters) and appears in US liquid formulation, brewing, and chemical dosing. Because a US gallon is a large volume, the numeric density in oz/gal is much larger than in g/cm³, scaling by roughly 133.5.
Conversion Formula
To convert grams per cubic centimeter to ounces per US gallon, multiply by this factor:
Step-by-Step Example
Convert 25 grams per cubic centimeter to ounces per US gallon.
How to Convert grams per cubic centimeter to ounces per US gallon
This conversion scales a metric density up to imperial ounces per US gallon with one fixed factor.
- Take the density in g/cm³: Note your value in grams per cubic centimeter.
- Multiply by the factor: Multiply by 133.5265 to switch to ounces per US gallon.
- Report in oz/gal: The result is the density in ounces per US gallon.
- Worked result: 25 g/cm³ × 133.5265 = 3338.16 oz/gal.

What is the Gram per Cubic Centimeter?
The gram per cubic centimetre is a metric unit of density widely used in chemistry, materials science, and geology because most solids and liquids have convenient single- or double-digit values in these units.
Definition
One gram per cubic centimetre is one gram of mass in a volume of one cubic centimetre. Since a cubic centimetre is one millionth of a cubic metre and a gram is one thousandth of a kilogram, the unit equals exactly 1000 kilograms per cubic metre.
It is numerically identical to the gram per millilitre and to the tonne per cubic metre.
Origin and History
The unit arose from the centimetre-gram-second (CGS) system introduced in the 19th century, in which it was the standard measure of density. It was historically anchored to water: the gram was originally defined so that one cubic centimetre of water at maximum density weighed almost exactly one gram, giving water a density near 1 g/cm³.
Law and Notable Facts
Though CGS has been superseded by SI, the gram per cubic centimetre remains the everyday unit for tabulating densities of materials. A substance with density less than 1 g/cm³ floats on water while a denser one sinks. Osmium and iridium, the densest naturally occurring elements, sit around 22.6 g/cm³.
Real-World Examples and Conversions
- Water at 4 °C: about 1.000 g/cm³ (1000 kg/m³).
- Aluminium: about 2.70 g/cm³; iron: about 7.87 g/cm³.
- Gold: about 19.3 g/cm³ (19300 kg/m³).
- 1 g/cm³ = 1000 kg/m³ = 1 g/mL = 1 kg/L.
What is the Ounce per US Gallon?
The ounce per US gallon is a unit of density expressing the mass in avoirdupois ounces contained in one US liquid gallon. It appears in everyday US contexts such as mixing ratios, water treatment, and beverage or fuel formulations.
Definition
One ounce per US gallon equals the mass of one avoirdupois ounce (28.349523125 g) divided by the volume of one US liquid gallon (3.785411784 L).
Here the ounce is the avoirdupois ounce of mass and the gallon is the US liquid gallon (exactly 3.785411784 L, or 231 cubic inches). Using the imperial gallon (4.54609 L) instead gives a different value of about 6.236 kg/m³, so the gallon variant must always be specified.
Origin and History
The US gallon descends from the English wine gallon of 231 cubic inches, retained by the United States after Britain adopted the larger imperial gallon in 1824. Pairing it with the avoirdupois ounce created a practical density and dosing unit for American trade and agriculture.
Law and Notable Facts
This is a derived unit fixed by the exact definitions of the avoirdupois ounce and the US liquid gallon. It is especially common in dosing and concentration work, where an "ounces per gallon" rate is easy to measure and mix by hand.
Real-World Examples and Conversions
- Water (about 1000 kg/m³) corresponds to roughly 133.5 oz/gal.
- A concentration of 1 oz/gal is about 7.489 kg/m³, or 7.489 g/L.
- 8 oz/gal (a half pound per gallon) equals about 59.9 kg/m³.
- 16 oz/gal (one pound per gallon) equals about 119.8 kg/m³.
Frequently Asked Questions
What is the conversion factor from g/cm³ to oz/gal?
One gram per cubic centimeter equals about 133.527 ounces per US gallon, reflecting the large size of the US liquid gallon.
Which gallon does this use?
It uses the US liquid gallon of about 3.78541 liters, not the larger imperial gallon, so the factor differs from any UK-gallon version.
Where is ounces per US gallon useful?
It is handy in US brewing, liquid chemical dosing, and formulation, where ingredient mass per gallon of product must be tracked.
What is water's density in oz/gal?
Water at about 1 g/cm³ is roughly 133.5 oz/gal, close to the well-known figure of about 8.34 pounds per US gallon.
How do I convert back from oz/gal to g/cm³?
Multiply the oz/gal value by about 0.00748915; for example, 133.527 oz/gal returns 1 g/cm³.
