How figure out 1.25 pints equals oz?

Answer 1

in liquid measure 1 pint = 16oz.

so 1.25 pints = 16 + 4oz

1.25 pints = 20oz

Answer

The conversion from pints to dry ounces can only be done easily for water and then at 4oC. For all other liquids and water at other temperatures the ratio does not hold due to the differing density of water. In America the fluid ounce is 1/16 of a pint but the dry ounce is either an avoirdupois ounce or a troy ounce. In the Imperial system once used in Britain and its Commonwealth there were 20 fluid ounces in a pint.

With conversions and all 1.25 American pints = 1 Imperial pint= 20 fluid ounces
