What is the difference between a Fluid Ounce and an Ounce?

Fluid ounces (fl oz.) are used to **measure fluids/liquids **while an ounces (oz.) are used for **dry measurements**. Thus, fluid ounces are used to measure *volume* and ounces are used to measure *weight*.

Therefore, you need to know what it is you are measuring and not the object you are measuring from. For example, if you are using a cup to measure, you used fluid ounces if the cup contains milk. Whereas, if the cup contains sugar, you use ounces.

Volume Measure |
Equivalent in Fluid Ounces |

1 tablespoon | \(\frac{1}{2}\) fluid ounce |

1 cup | 8 fluid ounces |

1 pint | 16 fluid ounces |

1 quart | 32 fluid ounces |

1 gallon | 128 fluid ounces |

`Example 1`

Honey is poured into a jug that is equivalent to 3.5 quarts. How many fluid ounces are in 3.5 cups?

`Solution`

First, honey is a fluid/liquid, so fluid ounces are the correct measurement and not ounces.

\[ 3.5\, quarts \times \frac{32\, fl. oz.}{1\, quarts} = 112\, quarts\]

`Example 2`

We have 21 fluid ounces of juice. How many cups of juice do we have?

`Solution`

We know that 1 cup is equivalent to 8 fluid ounces. Using this, we get

\[21\, fl. oz. \times \frac{1\, cup}{8\, fl. oz.} = \frac{21}{8}\, cups = 2.625 \,cups\]
