What is a Gallon?

What is a Gallon
A gallon contains 128 fluid ounces, so what comprises half of that?

In the US, we measure liquid volume in a complex system. A U.S. gallon is comprised of 128 fluid ounces. There are two types of fluid ounces: U.S. vs Imperial. In the US, 1 fl oz equals 29.6 ml. The Imperial British fl oz is 28.4 ml. The word gallon has roots in Latin for container.

Half of 128 oz is 64 oz. So a U.S. half-gallon is 64 fl oz precisely. It’s common for milk, juice, water, and other beverages. Half gallon containers help dispense a useful amount for drinking, mixing, cooking.

Remember, it’s not the same as a half-gallon in the UK. Their Imperial system is different.

What is an Ounce?

What is an Ounce
You’d weep realizing your measuring cup holds too little. When measuring liquids, the ounce is a unit of volume, not weight. In the US, a fluid ounce equals about 30 milliliters. The UK fluid ounce is slightly smaller at 28 milliliters.

To complicate things further, the Imperial system uses a separate ounce for mass versus volume. For recipes and measurements, focus on the fluid ounce, which equates to 1/128 of a US gallon.

Converting between gallons, quarts, pints, cups and ounces requires care – mismeasuring ingredients can ruin your baked goods or cocktails. With practice, you’ll commit the conversions to memory. For now, use charts, calculators or apps to double-check your amounts.

Precise measuring instruments help ensure accuracy when portioning sauces, mixing drinks or canning fruits and veggies.
