Answer key: Milliliters to Fluid Ounces worksheet

1. In milliliters: 14,786.76 mL
1. Start with the conversion factor: 1 US fl oz is exactly 29.5735295625 mL
  $1 US fl oz$ $= 29.5735295625 mL$
2. Multiply your US fluid ounces by 29.5735295625 to get milliliters
  $500 US fl oz \times 29.5735295625$ $= 14,786.7647813 mL$
2. In US fluid ounces: 18.6 US fl oz
1. The official definition goes the other way: 1 US fl oz is exactly 29.5735295625 mL
  $1 US fl oz$ $= 29.5735295625 mL$
2. So divide your milliliters by 29.5735295625 to get US fluid ounces
  $\frac{550 mL}{29.5735295625}$ $= 18.597712486 US fl oz$
3. Or multiply by 0.0338140227018 instead. It gives the same answer, because 1 ÷ 29.5735295625 ≈ 0.0338140227018
  $550 mL \times 0.0338140227018$ $= 18.597712486 US fl oz$
3. In US fluid ounces: 14.2 US fl oz
1. The official definition goes the other way: 1 US fl oz is exactly 29.5735295625 mL
