# How Much Is 100 Ml In Ounces

## Understanding the Conversion: How Much Is 100 Ml In Ounces

If you like to travel, it really helps to have a good grasp on the conversion between ounces and 100 ml. Knowing how mass and volume relate to these measurements will help you comply with the TSA liquids rule and just make life easier for everybody. Below, I’ll walk you through some conversions on ounces to 100 ml and give you some tips for dealing with TSA when deciding to bring through your liquids.

### Why travelers need to know ounces to 100ml

If you know your conversions, you’ll be able to better shop around for items to take with you on your travels without the risk of having to throw stuff away. But most of all, you’ll know the difference between mass and volume. Mass is related to weight and can be measured in grams or ounces (among other things). Volume is related to size and can be measured in liquid/fluid ounces or milliliters. It’s also popular to measure volume using the household measurement system where one cup equals 8 fluid ounces. The TSA Liquids 3-1-1 Rule states that you can only bring liquids in containers no larger than 3.4 liquid ounces (100 milliliters) and that all of your liquid containers must fit “comfortably” into one clear, quart-size bag.

### TSA Liquids 3-1-1 Rule

The TSA Liquids 3-1-1 Rule states that you can only bring liquids in containers no larger than 3.4 liquid ounces (100 milliliters) and that all of your liquid containers must fit “comfortably” into one clear, quart-size bag. TSA uses 3.4 ounces because it’s easier to remember but really 100 ml comes out to 3.3814 fluid ounces. Whenever you’re going through the checkpoint, you’ll have to remove your quart-size bag from your luggage (unless you have TSA Pre-Check) so that your liquids can be screened separately. TSA has a pretty broad definition of what is considered a “liquid.” Any types of creams, gels, lotions, etc., are all considered liquids. Basically anything that is usually poured, pumped, scooped, squeezed, slurped, or mashed will be considered a liquid for TSA purposes.

### Ounces to 100ml conversion chart

To help you make easy conversions from weight ounces to 100 ml (or ~3.4 fluid ounces), we’ve put together a helpful chart below. Keep in mind that sometimes the conversion will differ based on the exact composition of your product. But these numbers should at least be in the ballpark.

### What to do with the information

Knowing how weight ounces translate to liquid ounces and milliliters is really helpful. Let’s say you wanted to bring a 4 ounce container of 100% Raw Georgia (USA) Wildflower Honey Comb + Honey through airport security. If you know your conversions then you would know that 4 ounces of honey occupies less than 3.4 liquid ounces and could (possibly) be brought on a plane. But there are two different routes with TSA that you can go with your knowledge on conversions.

### Safe route

The safe route is when you transfer your liquid items out of the original container you purchased it in and into a TSA approved liquid container. This is very doable for certain types of things like alcohol but less practical with something like toothpaste which you would like to just leave in the original container. This is the safe option because TSA agents should allow your liquids to go through without an issue: 1) as long as they are in a container 3.4 ounces or smaller and 2) not hazardous. If you know your conversions, you’ll also be able to plan out how many containers you can fill up and should be able to do so pretty accurately.

### The more risky option

The more risky route would be to just leave your liquids in the original container. Let’s say that you had a container full of that delicious Raw Georgia Honey that weighed 4 ounces. That amount of honey would be under 100 ml. Assume the honey is filled to the top of the container, that means that you’d have a TSA compliant liquid container because it would have volume no larger than 100 ml or 3.4 fluid ounces. If the container stated fluid ounces on the label you could show that to a TSA agent and there probably would be no issue.

### Final word

Overall, it’s really helpful to know the relationship between ounces/grams and weight and liquid ounces/milliliters and volume. This is especially true if you plan on bringing items that fall under the TSA liquids category but are not simply water that has a perfect 1:1 ratio of weight to liquid ounces.

## Conversion of 100 Milliliters to Ounces

The conversion factor from mL to oz is 0.03381402265. To convert any value of mL to oz, multiply the mL value by the conversion factor. To convert 100 mL to oz, multiply 100 by 0.03381402265 (or divide by 29.5735296), that makes 100 mL equal to 3.3814023 oz.

### What is a Milliliter?

Milliliter (millilitre) is a volume unit in the metric system. The symbol is “mL”.

### What is a Fluid Ounce?

Fluid ounce is an Imperial and United States Customary measurement systems volume unit. 1 US fluid ounce = 0.03381402265 mL. 1 UK fluid ounce = 28.4130625 mL. The symbol is “fl oz”.

### Quick conversion chart of ml to oz

1 ml to oz = 0.03381 oz, 10 ml to oz = 0.33814 oz, 20 ml to oz = 0.67628 oz, 30 ml to oz = 1.01442 oz, 40 ml to oz = 1.35256 oz, 50 ml to oz = 1.6907 oz, 100 ml to oz = 3.3814 oz, 200 ml to oz = 6.7628 oz.

Definition: Millilitre – The millilitre (ml or mL, also spelled milliliter) is a metric unit of volume that is equal to one thousandth of a litre. It is a non-SI unit accepted for use with the International Systems of Units (SI). It is exactly equivalent to 1 cubic centimetre (cm³, or, non-standard, cc). Definition: Ounce – Note that this is a fluid ounce measuring volume, not the typical ounce that measures weight. It only applies for a liquid ounce in U.S. measurements.
