In the event you wish to journey it actually helps to have a superb grasp on the conversion between ounces and 100 ml.
Figuring out how mass and quantity relate to those measurements will provide help to adjust to the TSA liquids rule and simply make life simpler for everyone.
Beneath, I’ll stroll you thru some conversions on ounces to 100 ml and provide you with some suggestions for coping with TSA when deciding to carry by way of your liquids.
Why vacationers have to know ounces to 100ml
If you recognize your conversions, you’ll be capable to:
- Higher store round for objects to take with you in your travels with out the chance of getting to throw stuff away.
- Higher persuade a TSA agent to chorus from throwing out your objects
However most of all, you’ll know the distinction between mass and quantity.
I do know to many individuals this appears apparent however a number of us by no means actually acquired a superb grasp of this at school.
Mass is expounded to weight and might be measured in grams or ounces (amongst different issues).
(I name these kind of ounces weight ounces on this article to make issues 100% clear).
Quantity is expounded to measurement and might be measured in liquid/fluid ounces or milliliters.
It’s additionally well-liked to measure quantity utilizing the family measurement system the place one cup equals 8 fluid ounces.
I speak concerning the TSA liquids rule beneath however simply take into account that it applies to quantity — not mass.
Now that we acquired the fundamentals out of the way in which, let’s begin off with a fast refresher of the liquids rule in order that issues will make just a little extra sense.
TSA Liquids 3-1-1 Rule
The TSA Liquids 3-1-1 Rule states that you could solely carry liquids in containers no bigger than 3.4 liquid ounces (100 milliliters) and that all your liquid containers should match “comfortably” into one clear, quart-size bag.
TSA makes use of 3.4 ounces as a result of it’s simpler to recollect however actually 100 ml comes out to three.3814 fluid ounces.
Anyway, everytime you’re going by way of the checkpoint, you’ll must take away your quart-size bag out of your baggage (until you will have TSA Pre-Test) in order that your liquids might be screened individually.
TSA has a fairly broad definition of what’s thought-about a “liquid.”
Any varieties of lotions, gels, lotions, and so forth., are all thought-about liquids.
Principally something that’s often poured, pumped, scooped, squeezed, slurped, or mashed might be thought-about a liquid for TSA functions.
The massive caveat right here is that objects which can be thought-about liquids don’t all have the identical density.
Which means that the web weight that you simply see on packaging doesn’t have to be 3.4 ounces or below so as so that you can transport the contents of that container by way of TSA.
For instance, let’s say that you simply had a bundle of toothpaste that was 4.5 ounces in internet weight.
Given the density of toothpaste which is 1.3 g/ml, you possibly can refill a 3.4 fluid ounce container to the brim along with your 4.5 weight ounces of toothpaste.
On the flipside, if one thing isn’t very dense you could be shocked how rapidly it fills up 3.4 fluid ounces.
For instance, whipped cream solely takes about 1.75 weight ounces to refill a 3.4 liquid ounce container.
It’s because solely water and liquids with the same density have a ratio that works out completely to: 1 fluid ounce = 1 weight ounce (28.3495 grams).
Substances with different densities don’t work out like that.

What to do with the knowledge
Figuring out how weight ounces translate to liquid ounces and milliliters is basically useful.
Let’s say you wished to carry a 4 ounce container of 100% Uncooked Georgia (USA) Wildflower Honey Comb + Honey by way of airport safety.
If you recognize your conversions then you definitely would know that 4 ounces of honey occupies lower than 3.4 liquid ounces and will (probably) be introduced on a airplane.
However there are two completely different routes with TSA that you could go along with your information on conversions.
First, you may take the protected route.
The protected route is while you switch your liquid objects out of the unique container you bought it in and right into a TSA permitted liquid container.
That is very doable for sure varieties of issues like alcohol however much less sensible with one thing like toothpaste which you wish to simply depart within the authentic container.
That is the protected choice as a result of TSA brokers ought to permit your liquids to undergo with out a difficulty: 1) so long as they’re in a container 3.4 ounces or smaller and a pair of) not hazardous.
If you recognize your conversions, you’ll additionally be capable to plan out what number of containers you may refill and may give you the option to take action fairly precisely.
The extra dangerous choice
The extra dangerous route can be to simply depart your liquids within the authentic container.
Let’s say that you simply had a container stuffed with that scrumptious Uncooked Georgia Honey that weighed 4 ounces.
That quantity of honey can be below 100 ml.
Assume the honey is crammed to the highest of the container, that implies that you’d have a TSA compliant liquid container as a result of it could have quantity no bigger than 100 ml or 3.4 fluid ounces.
If the container said fluid ounces on the label you possibly can present that to a TSA agent and there in all probability can be no subject.
The issue is that the packaging for our Uncooked Georgia Honey simply says “NET WT 4oz.”
A TSA agent who isn’t well-informed on quantity versus mass, and who’s working in a doubtlessly hectic safety line, could not make the connection.
On this case, you possibly can inform them “the container exhibits ounces in weight but it surely really holds lower than 3.4 fluid ounces.”
Whether or not or not that may really work is one other query.
But when you recognize your conversions at the very least you may have them in your again pocket within the occasion it is advisable make clear why you might be compliant with the liquids rule.
General, it’s actually useful to know the connection between ounces/grams and weight and liquid ounces/milliliters and quantity.
That is very true in the event you plan on bringing objects that fall below the TSA liquids class however should not merely water that has an ideal 1:1 ratio of weight to liquid ounces.
