Mostly in big and well-known countries of the world, the conversion of 16 ounces to a cup is almost the same. 16 ounces is equals to 2 measuring cups.
Calculation: calculation of 16 ounces is very easy 1 ounce = 0.125 cup if we want to find 16 ounces into a cup then we simply multiply 0.125 with 16 to get the answer.

16 ounces * 0.125 cups = 2 cups

What is an ounce?

An oz is a unit of weight of one-sixteenth of a pound avoirdupois (approximately 28 grams).

Units like weight, mass, or volume come under the ounce category, used in most British derived customary systems of measurement

The common avoirdupois ounce is (approximately 28.3 g) or you can say that ​1⁄16 of a common avoirdupois pound; this is the United States customary and British imperial ounce. In United State, the unit ounce is used to measure packaged foods and food portions, postal items, areal density of fabric and paper, boxing gloves, and so on; but sometimes also elsewhere in the Anglosphere.

Apart from common ounce, some other ounces are using as a measuring unit.

  • The troy ounce of 31.1034768 grams is used for the mass of precious metals such as gold, silver, platinum, palladium, rhodium, etc.
  • The ounce-force is a measure of weight, that is, force
  • The fluid ounce is a measure of volume

In the United Kingdom, it is not using as a standard measuring unit. In 2000 it ceased but still, it is using on an informal basis but still, it is a legal standard of measuring in the united states.

International troy ounce

The abbreviation of a troy ounce is (oz t). one troy oz is equal to 480 grains. Consequently, there are exactly 31.1034768 grams in the international troy ounce.

Now a days, the troy ounce is used just to express the mass of precious metals such as gold, silver, palladium, rhodium or platinum . The most common products produced and marketed in troy ounces are bullion coins.

Fluid ounce

A fluid ounce (abbreviated fl oz, fl. oz. or oz. fl.) is a unit of volume, in the imperial system, it is equal to about 28.4 ml or about 29.6 ml in the US system. The fluid ounce is sometimes called an “ounce” in applications where its use is implicit, such as bartending (work for bars to serve drinks)

What is a cup?

The cup is a cooking measure of volume, commonly associated with cooking and serving sizes. In US customary units It is equal to half a liquid pint, or an amount between 200 ml and 250 ml (​1⁄5 and ​1⁄4 of a liter) in the metric system, it can vary due to location. Due to this reason actual drinking cups may vary from the size of this unit, standard measuring cups are usually used instead.

There are different kinds of cups which are using in different countries are given below.

United States

Three types of cups are using in the united states.

Customary cup

Legal cup

Coffee cup

Customary cup

US customary cup [c (US)] is a volume unit. It is half of a liquid pint. The table below shows all the measures into a cup.

1 US customary cup = ​1⁄16 US customary **gallon
= ​1⁄4 US customary quart
= ​1⁄2 US customary pint
= 8 US customary fluid ounces
= 16 US customary tablespoons
= 48 US customary teaspoons
= 236.5882365 milliliters exactly
= 15.7725491 international tablespoons
= 11.829411825 Australian tablespoons
​5⁄6 imperial cups
8 ​1⁄3 imperial fluid ounces

Legal cup

Legal US cup is a measuring cup used in cooking units, serving sizes, and nutrition labeling. It is defined in United States law as 240 ml = 1 US legal cup or 8 ounces = 1 legal cup

1 US “legal” cup = 240 milliliters

20 oz to cup [Can] = 2.60211 cup [Can]
30 oz to cup [Can] = 3.90316 cup [Can]

United Kingdom cup

The UK has its standard cup. It was set as 10 imperial fluid ounces or half an imperial pint. Historically in UK’S kitchen, there was a trend of using scales, and ingredients were measured by weight, rather than volume. 5 fluid oz or imperial cup was commonly used to measure liquid in old cookbooks and it is still using in fraction form like this 1/4, 1/5, and 1/6.

Here is a table shows conversion from ounce to cup in the United Kingdom.

Question answer section

A lot of question comes in mind when we think about measuring units, here we discuss ounces and cup so, here are some answers regarding the topic.

Q1. How many 16 oz bottles of water are equal to 10 cups of water in a recipe?

Thinking with my other ‘credential’ more math teachers. We have conversion factors we need



Using some old-fashioned unit calculations, we have

10cups|8oz.|1bottle / xxxx|1cup|16oz

Note units on top cancel with units on the bottom, you multiply top values and divide out bottom values, the XXXX, is just a place holder since we start with 10 cups; 8 oz per cup so 80 oz, then 16 oz per bottle so 5 total bottles.

Q2. How many 16 oz water bottles are equal to 64 oz?

Its answer is very simple if we want to know that how many 16 oz bottles we need to make it equals 64 oz, then we need to multiply 64 oz with 1 which equals 64 then we divide it with 16. It can be written like this:
64 * 1 / 16 = 4

So, its answer is 4. We need 4 16 oz bottles to make it equals 64 oz

Q3. How many 16 fl oz water bottles are 2 gallons?

It depends upon the fluid ounce on your gallon.

16.9 Imperial Fluid ounces are 480.2 ml. An Imperial gallon is 160 Imperial fluid ounces, so there are 9.467 bottle contents in a gallon.

16.9 US fl. ounces is 499.8 ml. This suggests to me that the intention of the “16.9 fluid ounces” is a US American obfuscation for “half a liter”. A US gallon has 128 US fluid ounces, so it would be 7.73 US fluid ounces in a US gallon.

A US gallon is 3.7854 liters, so there would be 7.883 Imperial 16.9 fluid ounce bottle contents in a US gallon.

An Imperial gallon is 4.546 liters, so there would be 9.01 US fluid ounce bottle contents in an Imperial gallon.

Simply it can be calculated like this

16 oz = 1 pint
2 pints = 1 quart
4 quarts = 1 gallon, so 8 pints = 1 gallon


1 gallon = 128 fl oz
128/16=8 bottles to a gallon

Two gallons will be 16 bottles 8×2=16

Q4. How much plastic would I save by buying a gallon of water bottled instead of 16-ounce bottled water?

Let’s do a comparison between a 5-gallon plastic water container and the 16.9 fl oz water bottle.

A small bottle contains 12 gm of plastic including lid and label. There are 37.8 of these bottles in 5 US gallons so the total amount of plastic used to bottle five gallons using 38 bottles is 456 gm.

A 5-gallon container, with lid label and handle, weighs 768 gm. That is around 70% more than individually packed small bottles of water.

Q5. What “does ounce-for-ounce” means?

“Ounce-for-ounce” means the actual unit of weight for an ounce. It equals 28.34 grams, 437.5 grains, 1/16 of a pound, or one fluid ounce, (32 ounces equals a quart).

If we figure out it, the ratio weight of an object compared to its value. For example, gold is more valuable than aluminum.


The repeatedly asked question regarding topics is given below.

1. Is 1 cup dry the same as 1 cup liquid?

Yes, technically the measurement in 1 dry cup is the same as the 1 cup liquid.

2. What size cup is 6 oz?

1 ounce equals 0.125 cups. So, if we multiply 6 with 0.125 then the answer is 0.75

6*0.125=0.75 (6 ounce equals 0.75 cup)

3. How many glasses of water in 16 ounces?

A cup equals 8 ounces; some glasses are 16 ounces. If we want to drink in a cup then 2 cups equal to 16.

4. Is 16 ounces of water in a day enough?

The institute of medicine (IOM) recommends that a man should drink 101 ounces of water that equals almost 13 cups and a woman should drink at least 74 ounces of water in a day which equals 9 cups.

5. Does tea count as water?

Juices and sports drinks are also hydrating – you can lower the sugar content by diluting them with water. Coffee and tea also count in your tally. Many used to believe that they were dehydrating, but that myth has been debunked. The diuretic effect does not offset hydration.
