## How many pounds in a gallon?

The weight of a gallon of liquids such as milk, gasoline, liquid propane or beer is dependent upon the density of the liquid in question. And the density of a liquid can often depend upon the temperature at which it is being stored. To give a simple explanation, a gallon of water at room temperature will weigh less than a gallon of honey (because honey is a denser substance).

When making a conversion, it's important to remember that the US gallon is smaller than the imperial (UK) gallon. In the US, a gallon is equivalent to 128 fluid ounces. But, in the UK an imperial gallon is bigger at 160 fluid ounces.

With the above in mind, let's look at some approximation conversions from gallons to pounds for various liquids.

Liquid (1 gallon) | Density (g/ml) | Weight (lb) |
---|---|---|

Water | 0.998 g/ml | 8.329 pounds |

Beer | 1.01 g/ml | 8.429 pounds |

Cider | 1.007 g/ml | 8.404 pounds |

Crude Oil | 0.915 g/ml | 7.636 pounds |

Diesel (fuel) | 0.85 g/ml | 7.094 pounds |

Gasoline (petrol) | 0.737 g/ml | 6.152 pounds |

Honey | 1.42 g/ml | 11.85 pounds |

Ice Cream | 0.56 g/ml | 4.673 pounds |

Jet Fuel | 0.804 g/ml | 6.71 pounds |

Milk | 1.035 g/ml | 8.637 pounds |

Olive oil | 0.92 g/ml | 7.678 pounds |

Orange juice | 1.038 g/ml | 8.663 pounds |

## How much does a gallon of milk weigh?

A US gallon of milk weighs approximately 8.637 pounds, a quart weighs 2.16 pounds and a pint weighs 1.08 pounds. These weights are based upon a milk density of 1.035 g/ml.

## Weighing gallons of water

The precise weight of water varies according to its density, which in turn depends on its storage temperature. You can find out more in our article how much does a gallon of water weigh?

## Densities of liquids

It's important to note that the density (mass per unit volume) of a liquid can vary depending upon many factors. These include the ingredients within the liquid, the processing method and how it is subsequently stored. Many of the ingredient densities referenced within this converter and page come from the FAO / INFOODS Database (version 2).
