**How Many Ounces /OZ in a Gallon:** As we know there are numbers of units of mass and Ounces or OZ is one of them used in some systems of measurements. There are several of OZ like ounces use in measuring weights of liquids and Troy use in measuring the weight of precious metal. But today we’ll discuss about liquid measurement.

Some times we found its hard to convert how many Ounces in a Gallon or how many oz in a gallon. To get rid off this problem i’m going to provide you a table by which you can easily remember how many ounces are in a gallon. Not only gallons i’m also giving you the table of

- How much fluid in one ounce?
- How many ounces in a litter?
- How many cups in a quart?
- How many Cups in a gallon?
- How many quarts in a gallon?
- How many ounces in a quart?

In USA 1 fluid ounce = 29.5735 but if you are not doing any experiment then you can rounding up to 30ml and in UK 1 ounce of liquid = 28.4131 ml but you can rounding up to 28 ml. so Ounce to ml conversation is different in different country. so take a look at the below table.
