💡 Volume Tips

  • 1 fl oz = 29.5735 mL — multiply oz by 30 for a quick estimate.
  • Standard soda can: 12 fl oz = 355 mL. Water bottle: 16.9 fl oz = 500 mL.
  • 1 US cup = 8 fl oz = 236.6 mL (NOT 250 mL — metric cup is different).
  • Medicine: 1 teaspoon = 5 mL, 1 tablespoon = 15 mL = 0.5 fl oz.

How to Convert Fluid Ounces to Milliliters

To convert US fluid ounces to milliliters, multiply by 29.5735. One US fluid ounce equals exactly 29.5735 mL. Note: a fluid ounce (volume) is different from an ounce (weight). Also, US fluid ounces differ from UK (Imperial) fluid ounces — 1 UK fl oz = 28.4131 mL. This converter uses US fluid ounces, which are standard in American recipes, nutrition labels, and drink sizes. The milliliter (1/1000 of a liter) is used worldwide for liquid measurements.

The OZ to ML Formula

The formula is: mL = fluid ounces × 29.5735. For quick mental math, multiply by 30 (error < 1.5%). For cups: 1 US cup = 8 fl oz = 236.588 mL (NOT 250 mL — that's a metric cup used in Australia). For tablespoons: 1 tbsp = 0.5 fl oz = 14.787 mL. For teaspoons: 1 tsp = 1/6 fl oz = 4.929 mL ≈ 5 mL. These relationships make it easy to convert between kitchen measurements.

Common OZ to ML Conversions

  • 1 fl oz = 29.57 mL — the fundamental conversion
  • 2 fl oz = 59.15 mL — standard espresso double shot
  • 8 fl oz = 236.59 mL — 1 US cup
  • 12 fl oz = 354.88 mL — standard soda can
  • 16 fl oz = 473.18 mL — US pint
  • 33.814 fl oz = 1,000 mL — 1 liter

Common Drink Sizes (fl oz → mL)

  • Espresso shot: 1 fl oz = 30 mL
  • Standard shot (liquor): 1.5 fl oz = 44 mL
  • Juice box: 6.75 fl oz = 200 mL
  • Soda can: 12 fl oz = 355 mL
  • Water bottle: 16.9 fl oz = 500 mL
  • Wine bottle: 25.4 fl oz = 750 mL

OZ to ML Examples

Step-by-step conversions

Recipe: 3/4 cup milk in mL

  1. 3/4 cup = 6 fl oz
  2. 6 × 29.5735 = 177.4 mL
  3. Quick: 6 × 30 = 180 mL (close enough)
  4. Use 175 mL for a metric recipe

3/4 cup = 6 fl oz = 177.4 mL

Medicine: 2 tablespoons to mL

  1. 1 tablespoon = 0.5 fl oz
  2. 2 tablespoons = 1 fl oz
  3. 1 × 29.5735 = 29.57 mL
  4. Or: 2 × 15 mL = 30 mL (standard dose)

2 tbsp = 1 fl oz ≈ 30 mL

Frequently Asked Questions

How many mL is 1 fl oz?

1 US fluid ounce = 29.5735 mL. For quick cooking conversions, 30 mL is close enough (error < 1.5%). Note: 1 UK (Imperial) fl oz = 28.4131 mL, slightly smaller.

How many fl oz is 500 mL?

500 mL = 16.907 fl oz, commonly written as 16.9 fl oz. This is the standard size of a water bottle in the US.

Is a US cup 250 mL?

No. A US cup = 236.588 mL (8 fl oz), NOT 250 mL. The 250 mL "cup" is a metric cup used in Australia and some other countries. This 14 mL difference can matter in baking.

How do I convert fl oz to liters?

Divide fluid ounces by 33.814 to get liters. Example: 64 fl oz (half gallon) = 64 ÷ 33.814 = 1.893 liters. Or multiply fl oz by 0.02957 for liters.

What is the difference between fl oz and oz?

Fluid ounces (fl oz) measure volume (how much space a liquid takes up). Ounces (oz) measure weight/mass. For water, they're approximately equal (1 fl oz of water weighs ~1 oz), but for other liquids they differ. Honey: 1 fl oz weighs ~1.5 oz. Oil: 1 fl oz weighs ~0.8 oz.

How many mL in a tablespoon?

1 US tablespoon = 14.787 mL ≈ 15 mL. 1 US teaspoon = 4.929 mL ≈ 5 mL. In recipes and medicine, tablespoons and teaspoons are commonly rounded to 15 mL and 5 mL respectively.
