📖 About Ml to Oz

Beverage Volumetric Metrology & NIST SP 811 Standards

A fluid ounce (fl oz) measures liquid volume (not mass). There are two primary global standards:

  • US Customary Fluid Ounce: (1) / (128) US Gallon = 29.573530 mL
  • UK Imperial Fluid Ounce: (1) / (160) UK Gallon = 28.413063 mL
  • US FDA Nutrition Labeling: 30.000000 mL (rounded for dietary tables)

Primary Beverage Bottle Volume Benchmarks

  • 30 mL (Shot Glass): = 1.01 fl oz
  • 240 mL (Small Coffee): = 8.12 fl oz = 1.01 cups
  • 330 mL (Euro Beer Can): = 11.16 fl oz
  • 355 mL (US 12 oz Soda Can): 12.00 fl oz
  • 500 mL (Water Bottle): = 16.91 fl oz = 2.11 cups
  • 750 mL (Wine Bottle): = 25.36 fl oz = 3.17 cups
  • 1,000 mL (1-Liter Bottle): = 33.81 fl oz = 4.23 cups

Equations

  • US Fluid Ounces (fl oz) = Milliliters (mL)29.57353
  • Milliliters (mL) = Fluid Ounces (fl oz) × 29.57353

How to Use This Calculator

Enter your Volume Value to Convert (e.g. 500.0), Fluid Ounce Standard — choose from US Customary Fluid Ounce (29.574 mL / Standard US), UK Imperial Fluid Ounce (28.413 mL / British Pint), US Nutrition / FDA Labeling Ounce (30.000 mL), Beverage Packaging Benchmark — choose from Custom Volume Value, 30 mL Liquor Shot Glass (1.01 fl oz), 240 mL Small Coffee Mug (8.12 fl oz), and Conversion Direction — choose from Milliliters to Fluid Ounces (mL → fl oz), Fluid Ounces to Milliliters (fl oz → mL). Results update instantly as you type — adjust any value to compare scenarios.

Understanding Your Result

Unit conversion precision: round to the same number of significant figures as your original measurement. Converting 6 feet to meters gives 1.8288 m — but if your measurement was approximate (±1 inch), expressing more than 2 decimal places is false precision. For international trade and technical specifications, SI units (meters, kilograms, liters) are the standard. US customary units (feet, pounds, gallons) differ from Imperial UK units: 1 US gallon = 3.785 L vs. 1 UK gallon = 4.546 L.
