## USA metric system

According to the US system, a gallon of water has 128 ounces of water present in it. To calculate how many ounces are present in the gallon, you will go through the following steps:

- Know the Ounces: The first step is understanding the number of ounces in the water bottle.
- Divide by 128: In the US system, a gallon of water contains 128 ounces, so in this sense, you have to divide the number of ounces seen in step one by 128.
- Answer: The answer you will get as a result of the division will be the presence of water bottles in a gallon.
- Example: In a 500 ml bottle of water, which is the standard size, there are almost 17 ounces of water present. You will divide this into 128, and the remaining answer comes at around three rounds off, meaning that there is a total of 3 liters available in the bottle.

## UK metric system

- Divide by 160: You will divide the number of ounces identified in the first step by 160.
- Answer: The answer that you will get as a result of the division will be the presence of bottles of water in a gallon
- Example: A 500 ml bottle of water, which is the standard size, contains almost 17 ounces of water. If you use the metric system, you will divide this by 160. The remaining answer is about 4 liters of water.

Should a person drink an entire gallon in a day?
