187 mL = 6.32 fl. Oz.

What is an Ounce and How to Calculate It?

An ounce is a small unit of measurement. There are many types of ounces that measure several different units, such as mass, weight, or volume.

For this article, we’re mostly concerned with fluid ounces, or ounces that measure volume or liquid. The three most common types of fluid ounces is the U.S. Customary fluid ounce, ounces for the U.S. food label, and the Imperial fluid ounce. Continue reading to learn more about these types of fluid ounces.

You can calculate ounces in a variety of ways. The easiest way to measure ounces is using a food scale. Many food scales are built to measure the amount of ounces for the food you weigh.

Another way to calculate ounces is to convert the mass, volume, or weight of something into ounces from a unit of measure you already know. Let’s use the topic of this article as an example. If you know you have 187 mL, then use a common divider to calculate the equivalent in ounces.

If you convert to U.S. fluid ounces, divide 187 mL by 29.573. You’ll get 6.32 fluid ounces. 29.573 is the conversion factor and is a constant you use every time you convert mL to oz.

What is a Milliliter and How to Calculate It?

A milliliter (mL) is 1/1,000th of one liter. When you have 1,000 milliliter, you have one liter. A liter is the volume of one kilogram of water, equal to 1,000 cubic centimeters, 61 cubic inches, 0.001 cubic meters, or 1.75 pints.

You can calculate milliliter in a similar way as ounces. First, food scales can measure milliliter, and it’s one of the easiest ways to measure mL.

However, if you don’t have a food scale, then you can manually calculate mL by converting a volume you have from another unit of measure.

For example, if you have 100 oz of liquid, how many mL is that? Multiply 100 oz by 29.573. 29.573 is the conversion factor that will always remain constant no matter how many ounces you’re converting.

Ounce QuantityFormulaTotal mL
100 ounces100 x 29.5732,957 mL
50 ounces50 x 29.5731,479 mL
10 ounces10 x 29.573296 mL
1 ounce1 x 29.57329.6 mL

Can You Convert mL to Oz?

Yes, you can! You can do a simple calculation, and convert in less than a minute!

Divide the number of mL by the conversion factor, 29.573. That will convert your mL to oz.

In order to convert 187 mL, divide 187 by 29.573. You’ll get 6.32 fluid ounces.

How to Calculate Oz from 187 mL?

You can calculate ounces by dividing the number of mL you want to convert, by the conversion factor of ounces. Keep in mind that there are different types of ounces, including fluid ounces (that measure liquid), that have different conversion factors.

U.S. Customary Fluid Ounce (US Fl Oz)

A U.S. customary fluid ounce is 1/16th of a U.S. liquid pint, and 1/128th of a U.S. liquid gallon, or exactly 29.5735295625 mL. The U.S. fl. Oz. is about 4% larger than the imperial ounce.

To calculate 187 mL to oz using U.S. customary fluid ounce, divide 187 mL by the conversion factor of 29.5735295625. You’ll get 6.32 U.S. customary fluid ounces.

187 mL ÷ 29.5735295625 mL = 6.32 fl. Oz.

U.S. Food Label

Food labels in the U.S. can often label how many milliliters are in something. What if you’re reading a food label with mL, and you want to know what 187 mL to oz for U.S. fluid ounce is? Maybe you’re writing your own food label.

The conversion factor is 30. Every one fluid ounce is equal to 30 mL. Here is the calculation:

187 mL ÷ 30 mL = 6.23 fl. Oz.

Imperial Fluid Ounce (UK Fl Oz)

The Imperial fluid ounce is used in Europe. One imperial fluid ounce is equal to 28.4130625 mL. Divide 187 mL by 28.4130625 mL. You’ll get 6.58 fl. Oz.

187 mL ÷ 28.4130625 mL = 6.23 fl. Oz.

What Fl. Oz. To Use?

First, ask yourself, what type of fluid ounce do you want to convert? This will largely depend on what you’re using your conversion for.

If you’re living in the United States, making a European recipe that calls for 187 mL, then you’ll want to use U.S. fluid ounces. If you are calculating the amount of fluid ounces for a food label, then use the conversion factor for the U.S. food label.

It’s important to assess your goals and the reason you need to convert these numbers in the first place, before deciding what type of fluid ounce to use.

Milliliter and Ounce Abbreviations

It’s easier to work with these measurements when you can abbreviate the unit label quickly. If you’re cooking and you have to quickly calculate and write down how many mL is in ounces, you don’t want to write out the long words of milliliter and ounces.

Here are the abbreviations:

  • Milliliter = mL
  • Ounces = Oz.
  • U.S. Customary Fluid Ounces = U.S. Fl. Oz.
  • Imperial Fluid Ounce = UK Fl. Oz.

Is There a Difference Between a Liquid mL and Dry mL?

While a milliliter remains the same volume whether measuring liquid or dry ingredients, the weight can vary due to the density of the substance. For instance, 1 mL of water has the same weight as 1 gram, whereas 1 mL of flour might weigh less due to its lower density.

Is There a Difference Between a Liquid Oz and Dry Oz?

Similarly, the ounce remains almost the same whether measuring liquid or dry ingredients in terms of volume, but the weight can differ. Keep in mind that fluid ounces (US fl oz) for liquids and dry ounces might have slight variations due to density.

Also keep in mind, that different fluid ounce units of measure will yield slightly different results. If you’re converting 187 milliliters to U.S. customary fluid ounces, food label ounces, and imperial fluid ounces, all your ounces will slightly vary. See below:

Qty.U.S. Customary Fluid OuncesU.S. Food Label OuncesImperial Fluid Ounces
187 mL6.32 fl. oz.6.58 fl. oz.6.23 fl oz.

Does the differences in the fluid ounces matter in cooking and baking? Yes, they do! It’s important to be as exact as possible while cooking and especially baking, so you can yield consistent (and flavorful) results from your recipes every time.

Tips for Precise Pouring and Measuring

  • Choose the Right Tools: Just like a painter selects the finest brushes, you should choose the right measuring tools for the job. Utilize graduated measuring cups designed specifically for liquids and dry ingredient measuring cups for powders, flours, and other dry substances. This difference ensures accurate measurements, as each type of cup is calibrated to provide precise volumes for its intended contents.
  • Convert with Care: In recipes that use metric and imperial measurements, ensure you convert accurately. Use a reliable conversion chart or calculator to maintain the proper ratios, preserving the integrity of your culinary masterpiece. I recommend you bookmark this article, and sign up for my newsletter so you can follow when new conversion articles come out.
  • Use a Unit Converter: You can use a measurement converter, whether that’s googling one online, using an app on your phone, or food scale. Using a converter can be a quick and simple way to convert a variety of different measurements without having to know the math behind it. They can be useful to convert for tablespoons, teaspoons, U.S. and Imperial pints, U.S. and Imperial gallons, inches, meters, cups, and more.
  • Mind Your Eye Level: When measuring liquids in graduated measuring cups, always check the volume at eye level. This eliminates parallax errors, which can occur if you read the measurement from an angle. Accurate readings prevent over-pouring or under-pouring, leading to consistent and balanced flavors in your dishes.
  • Be Mindful of Density: Keep in mind that different ingredients have varying densities. A cup of chopped vegetables will have a different weight than a cup of grated cheese. Be sure to adjust your measuring technique based on the ingredient to maintain precision.
  • Practice Patience: Rushing through measuring can lead to inaccuracies. Take your time and measure with care, especially for critical components like leavening agents or spices that can impact the final taste and texture of your dish.
  • Taste and Adjust: Remember, precision is your ally, but don’t forget the essence of cooking – your palate. Taste as you go and make adjustments to seasoning and flavors as needed. The numbers guide you, but your intuition and creativity bring your dishes to life.
