US Standard Volume

These are the most common measurements:

  • Fluid Ounces
  • Cups
  • Pints
  • Quarts
  • Gallons

fluid ounce

Fluid Ounces (fl oz) are pocket-sized.

Virtually how much fits in a small medicine cup.

Fluid Ounce!

"Fluid Ounce" is used for volume, "Ounce" for mass, and they are different.

  • For example, i fluid ounce of honey has a mass of near ane.5 ounces!
  • But for water, 1 fluid ounce has a mass of nigh 1 ounce.

If y'all mean an ounce of fluid say "fluid ounce" ("fl oz")

cup 2/3

Cups

A small glass holds virtually 8 fluid ounces, which is also called 1 cup.

1 cup = 8 fluid ounces

Here we have 2/three cup (two-thirds of a loving cup) of milk, or about 5 fluid ounces

Past the fashion ... we can measure volume using special Measuring Cups ... !

pint

Pints

A pint is equal to 2 cups (case: a big glass of milk!)

1 pint = 2 cups = xvi fluid ounces

When measuring many cups of liquid all put together we might desire to use quarts.

A quart (qt) is the same thing as 4 cups or 2 pints.

1 quart = 2 pints = four cups = 32 fluid ounces

quart

If we nevertheless demand more liquid we can switch to using gallons.

A gallon (gal) is the same as 16 cups or eight pints or 4 quarts.  It is the largest liquid measurement.

(Note that a quart is a quarter of a gallon!)
