What Does 100 ml Look Like?

100 ML equals 3.4 OZ or 100 grams but many people mistake it with 4 OZ bottles.

A 100 millilitres bottle is the most common size of perfumes that you can see everywhere, but 450 ml and 1000 ml is most popular for other liquids.

But here is what a 100 ml looks compared with 1000 ml in bottles.

This is an example of 100 ml compared to a 1000 ml of shampoo.

Here is how 100 ml look like

The TSA and airlines do not allow those large bottles in carry-on baggage.

If you wanted to take more shampoo on a flight for instance, a 1000 millilitres bottle will give you 10 bottles of 100 ml / 3.4 oz, meaning you can travel with a full bottle of shampoo if you divide it into small 100 ml containers and fits well inside a toiletry bag.

We have already covered the exact measurements of a toiletry bag and why it is called a quart sized bag.

What Is 100 millilitres In Inches?

It is hard to identify the volume of 100 ml with its dimensions, also it is complicated, as most companies tend to make large bottles but fill them only with 100 ml of liquids,(it is for marketing purposes).

The best way to know if a bottle has a 100 ml in volume is to get an empty bottle, like this 3 FL OZ 89 ml Oursunshine Silicone Travel Bottles for Toiletries.

Is 100 millilitres Enough When You Travel ?

It really depends on your trip and the product you will need.

Actually sometimes you may need more than 3.4 oz / 100 millilitres of certain items and sometimes less.

But sometimes it is really better to take small containers rather than large ones, so you can save space inside your toiletry bag and carry-on bag in general.

There is also more chance that you will find some of the items at your destination.

We have gathered some of the essential items that you may want to travel with to show you how their 100 ml travel size will look like.

Products How much is 100 ml
Water/ and other drinks A 100 ml is a small bottle of 3.4 oz and it is really not enough for your flight, so it is better to bring water or fill your bottle after you pass the security checkpoint.
If you only have 100 ml, you won’t even have a full cup of water.
ShampooYou can find travel friendly shampoo bottles that come in 3.4 oz / 100 ml, but you will need to make sure that they will cover your needs during your trip.
Body washBody wash comes in large bottles and sometimes even in 34 oz / 1000 ml, you may want to take several small bottles of body wash in your quart size bag or place a large bottle in your checked bag.
SunscreenSunscreen usually comes in small bottles which is a great thing, as the spray is difficult to refill in other bottles.
Hair gelThe most common and regular size of hair gel is 6.8 oz / 201 ml which is larger than the allowed size in carry-on baggage, you will need to fill a small bottle.
ToothpasteToothpaste companies are already aware that travelers have such difficulties traveling with large tubes of toothpastes, thus they quickly adapt and provide travel friendly containers, so there is more chance that you will find your favorite toothpaste in small containers.
MascaraThe good thing about Mascara is most of the tubes are less than 3.4 oz / 100 millilitres and you can fit as many as you can in your toiletry bag.

Final Thoughts

The liquid limit is almost the same on most airlines and in both domestic and international flights, and they may refer to it in their regulations as 3.4 oz or 100 millilitres

You can find 3.4oz / 100 millilitres travel sized bottles in some products like shampoo and other toiletries, or you can opt for empty bottles and fill them with your desired toiletries.

However; it is not a good idea to take only one single bottle, especially for long trips.

A 100 ml bottle is not that big, so you will need to consider how many days and how many times you are going to use the product on your trip.

We hope this helps

Happy travels
