What Is a Milliliter (ml)?
A milliliter (ml) is a metric unit of volume that measures liquids. It is one-thousandth of a liter and is commonly used in cooking, baking, beverages, medicine, and science.
For example:
- 100 ml to oz ≈ 3.38 US oz
- 50 ml to oz ≈ 1.69 US oz
Milliliters allow precise measurements, making it easier to follow international recipes or medical instructions. Understanding ml is the first step in converting it accurately to ounces.
What Is an Ounce (oz)?
An ounce (oz) is an imperial unit of measurement. When measuring liquids, it is called a fluid ounce (fl oz).
- US fluid ounce: ≈ 29.5735 ml
- UK (Imperial) fluid ounce: ≈ 28.413 ml
Ounces are commonly used in recipes, drinks, bartending, and health measurements. For example:
- 30 ml to oz ≈ 1 US oz
- 60 ml to oz ≈ 2 US oz
Knowing the difference between weight ounces and fluid ounces ensures precise conversion.
