What is a Milliliter?
A milliliter (mL) is one-thousandth of a liter and is ubiquitous on packaging, lab glassware, and medical devices. It pairs naturally with teaspoons (5 mL) and tablespoons (15 mL) and scales up to liters (L) for larger volumes.
What is a UK Fluid Ounce?
A UK fluid ounce is an Imperial unit of liquid volume defined as exactly 1/160 of an Imperial gallon (4.54609 L), so one UK fl oz equals 28.4130625 mL. You’ll encounter it in brewing references, maritime documentation, and historical cookbooks.
Step-by-Step: Converting mL to UK fl oz
- Write down your volume in milliliters (mL).
- Divide by 28.4130625.
- Express the result in UK fl oz.
Example walkthrough:
Input: 355 mL
Divide: 355 ÷ 28.4130625 = 12.49425
Output: 12.49425 UK fl ozPrecision, Rounding & Significant Figures
For everyday use, 2–3 decimals are often enough. This tool defaults to 5 decimals for high precision. In technical contexts, keep significant figures consistent with your instruments and reporting standards to avoid rounding bias in chained calculations.
