Converting millilitres to ounces is useful when working with recipes, drinks, cosmetics, bottles and other liquid measurements.
The process is simple once you know the correct conversion factor.
However, there are two common types of fluid ounces: US and UK imperial.
ML to US Ounces Formula
The formula is:
For example, converting 100 ml:
100 ÷ 29.5735296 = 3.3814
Therefore, 100 ml equals approximately 3.38 US fluid ounces.
ML to UK Ounces Formula
For UK imperial fluid ounces, use:
For example:
100 ÷ 28.4130625 = 3.5195
Therefore, 100 ml equals approximately 3.52 UK fluid ounces.
Common Conversion Examples
| ML | US fluid ounces |
|---|---|
| 10 ml | 0.34 |
| 20 ml | 0.68 |
| 30 ml | 1.01 |
| 40 ml | 1.35 |
| 50 ml | 1.69 |
| 60 ml | 2.03 |
| 100 ml | 3.38 |
| 200 ml | 6.76 |
| 300 ml | 10.14 |
| 400 ml | 13.53 |
| 500 ml | 16.91 |
| 750 ml | 25.36 |
Can You Use 30 ML Instead of One Ounce?
For everyday estimates, 30 ml is often treated as approximately one US fluid ounce.
However, the exact US measurement is 29.5735 ml.
For more precise calculations, use the exact conversion factor.
Can You Convert ML into Dry Ounces?
Not directly. Millilitres measure volume, while dry ounces generally measure weight.
You need the density of the ingredient to convert between these measurements.
