How to convert milliliters to ounces

1 mL = 0.035274 oz, so multiply by 0.035274 to go from milliliters to ounces (avoirdupois). Going the other way, 1 oz = 28.3495 mL.

oz = mL × 0.035274
mL = oz × 28.3495

Worked example:

5 mL = 5 mL
× 1 g/mL (USDA FDC 174158, 1 ml = 1 g) = 5 g
= 0.176369809748 oz
