What Does 1.7 Fl Oz Mean in Perfume? Understanding Perfume Volume Measurements

Have you ever come across a perfume that’s labeled as 1.7 fl oz? If you're unsure about what that means and how much perfume you're actually getting, you're not alone. It represents approximately 50 ml of perfume, which is a decent amount to last you for a considerable period of time. However, it's important to note that perfumes are also available in other sizes, such as 2 fl oz (60 ml) and 3 fl oz (90 ml), which offer more product for those who prefer to have a larger supply.

What Does Fl Oz Mean on Perfumes?

FL. OZ. and ml are units of measurement used to quantify the volume of perfumes and other liquids. When we see 1.7 fl oz on a perfume bottle, it means that the volume of the fragrance is 1.7 fluid ounces. Fluid ounces, sometimes abbreviated as fl oz or oz, are the most common measurement used in the United States to express liquid quantities. In contrast, ml or milliliters are the standard unit of measure for volume in most other parts of the world, including Europe and Canada.

Now, lets understand the slight difference between the two fluid ounces. The US fluid ounce is slightly larger than the UK fluid ounce. 1 US fluid ounce is equivalent to approximately 29.57 milliliters, while 1 UK fluid ounce is about 28.41 milliliters. So, if we consider a perfume bottle labeled as 1.7 USFL., it will contain around 50 milliliters of fragrance. On the other hand, if it’s labeled as 1.7 UKFL., the volume will be slightly smaller, around 48 milliliters.

It’s important to note that the choice of measurement depends on the region and the regulations set by each country. This allows consumers all over the world to understand the size of the product. It’s worth mentioning that some countries also use other volume measurements, such as centiliters or ounces, so it’s always wise to check the label or consult a conversion chart if needed.

Understanding these perfume volume measurements is crucial when purchasing fragrances, as it helps you determine the amount of product you’ll be getting. It also allows you to compare prices and value for money across different brands and sizes.

However, there are some considerations to keep in mind when it comes to traveling with perfume. While the TSA’s 3-1-1 rule restricts you from carrying larger perfume bottles in your carry-on, there are still ways to bring your favorite fragrance along for your trip.

Can I Travel With 1.7 Oz Perfume?

When it comes to traveling with perfume, it’s important to understand the restrictions set by the Transportation Security Administration (TSA). According to the TSAs 3-1-1 rule, you can only bring travel-size containers that are 3.4 ounces or less in your carry-on bag. This means that if your perfume bottle is 1.7 fluid ounces (fl oz) or smaller, you can bring it with you in your carry-on.

Traveling with your favorite fragrance can enhance your travel experience, just remember to follow the rules and guidelines set by the TSA for a smooth and hassle-free journey.

What Happens if You Accidentally Bring a Perfume Bottle Larger Than 3.4 Ounces in Your Carry-On?

Accidentally bringing a perfume bottle larger than 3.4 ounces in your carry-on can result in it being confiscated by airport security. The Transportation Security Administration (TSA) imposes a limit on the volume of liquids that can be brought in carry-on bags for safety reasons. Bottles exceeding this limit are typically not allowed through security checkpoints. To avoid any issues, it’s important to adhere to the TSA regulations and pack your perfumes accordingly.

When it comes to perfume, the longevity of a 1.7 fl oz (50 mL) bottle depends on various factors, including the concentration and frequency of application. With an estimated 500-750 sprays, the duration can vary significantly. From 6 months for an Eau de Cologne sprayed four times daily to up to 2 years for a Parfum sprayed once a day, the longevity of your favorite scent is impacted by your personal usage.

How Long Does 1.7 Oz Perfume Last?

When it comes to understanding the volume measurements of perfume, 1.7 fl oz (50 mL) is a popular size for fragrance enthusiasts. But how long does a 1.7 oz perfume actually last? The answer depends on a few factors, including the concentration of the fragrance and how often it’s applied.

A 1.7 fl oz (50 mL) bottle of cologne or perfume typically contains around 500-750 sprays, depending on the design of the bottle and the intensity of the spray. This means that if you were to use your perfume four times a day, you could expect it to last for approximately 3-6 months. However, if you prefer a more subtle application and only use it once a day, you could extend it’s lifespan to around 1-2 years.

The longevity of a perfume also depends on it’s concentration. Fragrances usually come in various concentrations, such as Eau de Cologne (EDC), Eau de Toilette (EDT), Eau de Parfum (EDP), and Parfum. EDC has the lowest concentration of fragrance oils, typically around 2-5%, while parfum has the highest concentration, often ranging from 15-30%.

Considering this, a 1.7 oz bottle of EDC, which may need to be sprayed more often due to it’s lower concentration, may last for a shorter period compared to a parfum sprayed fewer times.

It’s important to note that personal application habits can vary greatly between individuals. Some people prefer a more generously applied fragrance, while others are more sparing with their spritzes.


In conclusion, understanding perfume volume measurements is essential when purchasing fragrances. By being aware of these measurements, consumers can make informed decisions and ensure they’re getting the desired amount of product.
