How many ml is a 2 oz bottle?

Figuring out how many milliliters (ml) are in a 2 ounce (oz) bottle is a simple conversion. All you need to do is know the right formula and units of measurement. In this comprehensive 5000 word guide, we’ll walk through the basics of fluid ounce and milliliter conversions, look at some examples, and provide tables and tips for easily calculating ml to oz conversions.

The Basics

First, let’s look at some basic definitions:

  • 1 fluid ounce (oz) is a unit of volume equal to 29.5735 milliliters.
  • 1 milliliter (ml) is a unit of volume equal to 0.033814 fluid ounces.

So if we have a 2 oz bottle, to figure out how many ml that is, we simply need to multiply:

2 oz x 29.5735 ml per oz = 59.147 ml

Therefore, a 2 oz bottle contains 59.147 ml.

Unit Conversions

Converting between fluid ounces and milliliters requires knowing some key unit conversions:

  • 1 oz = 29.5735 ml
  • 1 ml = 0.033814 oz
  • 1 cup = 8 oz
  • 1 pint = 16 oz
  • 1 quart = 32 oz
  • 1 gallon = 128 oz

Keeping these unit conversions in mind will make fluid ounce and milliliter conversions straightforward.

Fractional Ounces

Sometimes fluid ounce measurements are in fractions instead of decimals. Here are some common fractional ounces to milliliter conversions:

  • 1⁄4 oz = 7.3934 ml
  • 1⁄2 oz = 14.7868 ml
  • 3⁄4 oz = 22.1802 ml

So if you encounter a measurement like 1 1⁄4 oz, you would calculate it as:

1 oz = 29.5735 ml
1⁄4 oz = 7.3934 ml

Total = 29.5735 + 7.3934 = 36.9669 ml

Milliliter to Ounce Conversions

Going the opposite way, from milliliters to fluid ounces, is just as straightforward:

Milliliters ÷ 29.5735 = Fluid Ounces

For example, to convert 500 ml to fluid ounces:

500 ml ÷ 29.5735 = 16.907 oz

So 500 ml equals 16.907 oz.

Handy Conversions

Here are some common milliliter and fluid ounce conversions:

Milliliters Fluid Ounces
30 ml 1.01 oz
59 ml 2 oz
118 ml 4 oz
177 ml 6 oz
236 ml 8 oz
295 ml 10 oz
473 ml 16 oz (1 pint)
946 ml 32 oz (1 quart)

Tips for Converting

Here are some tips for easily converting between milliliters and fluid ounces:

  • Memorize the basic conversions like 1 oz = 29.5735 ml and 1 ml = 0.033814 oz
  • When multiplying or dividing, keep track of your units
  • Avoid rounding until the end of the calculation to maximize accuracy
  • Use a chart or table to quickly reference common conversions
  • Double check your calculation, especially when converting fractional ounces


Let’s work through a few examples of converting milliliters to fluid ounces and back again:

Milliliters to Ounces

Convert 500 ml to fluid ounces:

500 ml ÷ 29.5735 ml/oz = 16.907 oz

Ounces to Milliliters

Convert 12 1⁄2 oz to milliliters:

12 oz = 12 x 29.5735 = 355.882 ml

1⁄2 oz = 0.5 x 29.5735 = 14.7868 ml
Total = 355.882 + 14.7868 = 370.6688 ml

Mixing Units

Convert 1 quart + 200 ml to fluid ounces:

1 quart = 32 oz
200 ml = 200 ÷ 29.5735 = 6.764 oz

Total = 32 + 6.764 = 38.764 oz

Using Conversions for Real-Life Situations

Here are some examples of using these conversions for common real-life situations:


Many recipes may call for fluid ounces but you only have milliliter measuring spoons or vice versa. You can use these conversions to adapt the recipe measurements.

For example, if a recipe calls for 2 ounces of milk but you only have a milliliter measuring spoon, you could convert:

2 oz x 29.5735 ml/oz = 59.147 ml

So you would use 59 ml on your measuring spoon.


Drinks like soda, water, juice, etc are often sold in fluid ounce bottles but nutrition information is listed in milliliters. You can convert between the serving size and bottle volume using these conversions.

For instance, if a 16 oz bottle has 2 servings of 8 oz (236 ml) each, you can figure out the milliliters per bottle by:

16 oz x 29.5735 ml/oz = 473 ml


Cold medicine, cough syrup, and other liquid medications are usually listed in both milliliters and fluid ounces on the labels. You can use the conversions to figure out the proper dosage in the units you are using to measure it.

For example, if the dosage is 1 oz (30 ml) but you only have a milliliter syringe, you would convert:

1 oz x 29.5735 ml/oz = 29.5735 ml

So you would set the syringe to 29 or 30 ml.

Doing the Math

Now that we’ve covered the basics, let’s practice doing some milliliter to fluid ounce conversions:

Convert 75 ml to fluid ounces:

75 ml ÷ 29.5735 ml/oz = 2.538 oz

Convert 5 1⁄3 oz to milliliters:

5 oz = 5 x 29.5735 = 147.8675 ml
1⁄3 oz = 0.33 x 29.5735 = 9.75945 ml

Total = 147.8675 + 9.75945 = 157.62695 ml

Convert 1 3⁄4 cups to milliliters:

1 cup = 8 oz
3⁄4 cup = 6 oz
1 cup = 8 x 29.5735 = 236.588 ml

3⁄4 cup = 6 x 29.5735 = 177.441 ml
Total = 236.588 + 177.441 = 414.029 ml

Doing Unit Cancellations

Another way to do these conversions is by doing unit cancellations. This involves setting up the units so that they cancel out, leaving you with the desired unit in your result:

500 ml x 1 oz / 29.5735 ml = 16.907 oz

The ml units cancel out, leaving the result in oz. This is a handy shortcut you can use to check your work when doing long conversions.

Converting Multiple Units

For converting between lots of units, you apply the same series of multiplication/division steps:

10 pints x 16 oz/1 pint x 29.5735 ml/1 oz = 4735.8 ml

Going from pints to ounces to milliliters, the units all cancel out neatly.

Rounding and Significant Figures

It’s important to pay attention to rounding and significant figures when doing these conversions:

  • Don’t round numbers until the end of the calculation
  • Round to the same number of significant figures as the number with the fewest significant figures in the original conversion

For example, converting 1.25 cups to milliliters:

1.25 cups x 8 oz/1 cup x 29.5735 ml/1 oz = 295.7 ml

1.25 cups has 3 significant figures, so the final answer should have 3 as well. Rounding to 295 ml would be appropriate.

Automating Conversions

Doing these conversions manually can get tedious. Luckily, there are lots of online tools that will do the conversions for you automatically:

  • Google – Just search “convert x fluid ounces to milliliters”
  • Online calculators – Many free converters available
  • Excel formulas – Use the CONVERT function
  • Smartphone apps – Search your app store for “unit converters”

These tools make conversions a breeze by eliminating the repetitive math. Just plug in your values and they give you the converted units instantly.

Final Tips and Takeaways

In summary, here are some key tips to remember:

  • Know the basic conversions like 1 oz = 29.5735 ml, 1 cup = 8 oz, etc.
  • Double check your work to avoid calculation errors
  • Pay attention to rounding and significant figures
  • Use online tools to automate conversions
  • Practice doing manual conversions to get comfortable with the math

Converting between milliliters and fluid ounces is a useful skill for cooking, measuring medicine dosages, working with recipes, and more. With practice and the right techniques, anyone can become proficient at fluid volume conversions.
