How many milliliters of a soft drink are contained in a 12.0-oz can?

We know that

\(1\,fluid\,ounce\,\, = \,\,29.57\,mililitres\)

Now, using the above conversion factor between a fluid ounce and milliliters.

\(\begin{aligned}{}Volume\,of\,Soft\,drink\,in\,fluid\,ounce\,\, &= \,\,12\,ounce\\Hence,\\\,Volume\,in\,milliliters\,\,& = \,\,(Volume\,in\,fluid\,ounce)\,(29.57\,{{milliliters} \mathord{\left/ {\vphantom {{milliliters} {1\,fluid\,ounce}}} \right.} {1\,fluid\,ounce}})\\\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, &= \,\,12\,fluid\,ounce\, \times \,29.57\,{{milliliters} \mathord{\left/ {\vphantom {{milliliters} {1\,fluid\,ounce}}} \right.} {1\,fluid\,ounce}}\\\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, &= \,\,12\, \times \,29.57\,milliliters\\\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, &= \,354.84\,milliliters\end{aligned}\)

≃355 mL

As the magnitude in a unit of oz is smaller than in milliliters. When we need to conclude, check the magnitude properly.

The fluid ounce is 29.57 times milliliters.

A can of soft drink with 12 oz can contain 355 milliliters of volume.
