How the Conversion Works

This calculator uses a two-step conversion process through liters (L) as the base unit, which is the standard unit of volume in the International System of Units (SI).

Conversion Formula:

Step 1: Convert from fl oz (US) to liters (L)

Value in L = Input value ÷ 33.814

Step 2: Convert from liters (L) to mL

Result = Value in L × 1,000

Simplified Formula:

Result = Input × 29.5735494174
Where 29.5735494174 is the conversion factor from fl oz (US) to mL

Example Calculation:

Let's convert 16 fl oz (US) to mL:

16 fl oz (US) ÷ 33.814 = 0.473177 L
0.473177 L × 1,000 = 473.176791 mL

Result: 16 fl oz (US) = 473.176791 mL
