150 mL is equal to about 5.07 US fluid ounces. For everyday use, this is often rounded to about 5 fl oz.
In Imperial measurements used in the UK, 150 mL is about 5.28 Imperial fluid ounces. This article shows the conversion, related units, everyday examples, and a simple way to measure 150 mL.
How Many Ounces Is 150 mL?
The exact conversion depends on which type of fluid ounce you use.
150 mL = 5.0721 US fluid ounces
Rounded to two decimal places:
150 mL ≈ 5.07 US fl oz
For Imperial fluid ounces:
150 mL ≈ 5.28 Imperial fl oz
A US fluid ounce is about 29.5735 mL, while an Imperial fluid ounce is about 28.4131 mL. That is why the two answers are slightly different.
For most US recipes, drinks, and product labels, 5.07 US fl oz is the useful answer.
Also, fluid ounces measure volume. They are different from regular ounces used to measure weight.
How Much Is 150 mL in Cups and Other Units?
Here are some useful ways to express 150 mL:
| Unit | 150 mL Equals |
|---|---|
| US fluid ounces | 5.07 fl oz |
| Imperial fluid ounces | 5.28 fl oz |
| Liters | 0.15 L |
| Centiliters | 15 cL |
| Cubic centimeters | 150 cm³ |
| US cups | About 0.63 cup |
| Metric cups | 0.6 cup |
| US tablespoons | About 10.14 tbsp |
A US cup holds about 236.59 mL, so 150 mL is a little less than two-thirds of a US cup.
A metric cup is 250 mL, making 150 mL exactly three-fifths of a metric cup.
Everyday Examples of About 150 mL
Container sizes vary, so there is no single glass, cup, or bottle that always represents 150 mL. The examples below use labeled capacities or standard measuring units where possible.
1. A 150 mL Juice Container
Some small juice drinks are sold in containers labeled 150 mL. A product with that printed capacity gives you an exact example of the volume.
Juice boxes come in many sizes, though, so an ordinary juice box should not automatically be assumed to hold 150 mL.
2. A 150 mL Cosmetic Bottle
Small bottles of lotion, cleanser, shampoo, and other personal-care products are sometimes sold in 150 mL sizes.
If the label says 150 mL, its stated liquid capacity matches the target amount. Bottle shapes can look very different even when they hold the same volume.
3. About 10 US Tablespoons
One US tablespoon holds about 14.79 mL.
Ten tablespoons equal about:
10 × 14.79 = 147.9 mL
That is only about 2.1 mL less than 150 mL, so 10 tablespoons is a very close kitchen comparison.
4. About 30 US Teaspoons
One US teaspoon holds about 4.93 mL.
Thirty teaspoons equal approximately:
30 × 4.93 = 147.9 mL
That is close to 150 mL, although tablespoons are much quicker to use for an amount this large.
5. Five 30 mL Portions
Many medicine measuring cups and dosing containers include a 30 mL marking, although their total capacities vary.
Five accurately measured 30 mL portions make:
5 × 30 mL = 150 mL
Use the printed markings rather than assuming every medicine cup has the same capacity.
6. Three 50 mL Portions
Three measured portions of 50 mL equal exactly:
3 × 50 mL = 150 mL
This can be useful if you have a measuring container with a clear 50 mL line.
Some small bottles are also sold in 50 mL sizes, but their capacity should always be checked on the label.
7. Half of a 300 mL Bottle
If a bottle is labeled 300 mL, exactly half of its liquid volume is 150 mL.
This is an easy visual reference if you regularly use drinks, sauces, or personal-care products sold in 300 mL containers.
The bottle must actually be labeled 300 mL for the comparison to be reliable.
8. Slightly Less Than Two-Thirds of a US Cup
Two-thirds of a US cup is about 157.7 mL.
That makes 150 mL roughly 7.7 mL less than two-thirds of a cup.
For casual cooking, this can help you picture the amount, but a milliliter-marked measuring cup will be more accurate.
9. More Than Half a US Cup
Half a US cup is about 118.3 mL.
So 150 mL is about 31.7 mL more than half a cup. Visually, it sits between one-half and two-thirds of a US cup.
This is useful when a recipe gives milliliters but your measuring cup uses fractions.
10. About Five US Fluid Ounces
Five US fluid ounces equal about 147.87 mL.
That is only about 2.13 mL less than 150 mL, making 5 fl oz one of the easiest ways to picture the amount.
It is very close, but it is not an exact match.
How to Convert 150 mL to Fluid Ounces
To convert milliliters to US fluid ounces, divide the number of milliliters by 29.5735.
For 150 mL:
150 ÷ 29.5735 = 5.0721 US fl oz
Rounded:
150 mL ≈ 5.07 US fl oz
For Imperial fluid ounces, divide by about 28.4131:
150 ÷ 28.4131 ≈ 5.28 Imperial fl oz
If you only need a quick estimate, you can think of 150 mL as roughly 5 fluid ounces.
100–200 mL to Oz Conversion Table
Here are several nearby measurements using US fluid ounces:
| Milliliters | US Fluid Ounces |
|---|---|
| 100 mL | 3.38 fl oz |
| 120 mL | 4.06 fl oz |
| 125 mL | 4.23 fl oz |
| 150 mL | 5.07 fl oz |
| 175 mL | 5.92 fl oz |
| 200 mL | 6.76 fl oz |
The table shows that 150 mL sits almost exactly around the 5-fluid-ounce mark.
Final Thoughts
150 mL equals about 5.07 US fluid ounces, or roughly 5 fl oz for everyday use.
An easy way to picture it is about 10 US tablespoons, slightly less than two-thirds of a US cup, or the contents of a container specifically labeled 150 mL.
Common Questions
Is 150 mL Exactly 5 Oz?
No. 150 mL is about 5.07 US fluid ounces, while exactly 5 US fl oz is about 147.87 mL.
The difference is only around 2.13 mL, so 5 fl oz is often used as a convenient approximation.
How Many US Fluid Ounces Are in 150 mL?
There are approximately 5.07 US fluid ounces in 150 mL.
The more precise value is about 5.0721 US fl oz.
How Many Imperial Fluid Ounces Are in 150 mL?
150 mL is about 5.28 Imperial fluid ounces.
Imperial fluid ounces are slightly smaller than US fluid ounces, so the numerical result is higher.
Is 150 mL the Same as 5 Fl Oz?
Not exactly. Five US fluid ounces is about 147.87 mL, which is roughly 2.13 mL less than 150 mL.
For casual measuring, they are very close.
Is 150 mL an Ounce Measurement of Weight or Volume?
The conversion from 150 mL to ounces refers to fluid ounces, which measure volume.
Regular ounces measure weight or mass. You cannot convert 150 mL directly to weight ounces without knowing what substance is being measured because different liquids have different densities.
How Much Is 150 mL Without a Measuring Cup?
A close kitchen estimate is about 10 US tablespoons.
Ten US tablespoons hold roughly 147.9 mL, so they fall just over 2 mL short of 150 mL. For recipes that need precision, use a container marked in milliliters.
