Understanding Milliliters (mL) and Ounces (oz)
What is a Milliliter (mL)?
- A milliliter (mL) is a metric unit of volume.
- Used worldwide for measuring liquids.
- 1 mL = 1/1000 of a liter (about 20 drops of water).
What is an Ounce (oz)?
- An ounce (oz) is an imperial/US unit of volume.
- Commonly used in the US for liquids.
- 1 fluid ounce (fl oz) ≈ 29.5735 mL (US standard).
- UK fluid ounce ≈ 28.4131 mL (slightly different).
How to Convert mL to oz (Step-by-Step)
The Exact Conversion Formula
The basic formula is:
oz = mL / 29.5735
Example:
Convert 100 mL to oz
100 / 29.5735} ≈ 3.38 oz (US
Quick Estimation (Easy Method)
For a rough estimate:
- 30 mL ≈ 1 oz (close enough for cooking).
- So, 100 mL ≈ 3.3 oz (instead of 3.38 oz).
