# Is 16 fluid ounces equal to 1 pound?

## It could be...

A fluid ounce is a measure of volume while a pound is a measure of weight. A fluid ounce of a particular substance "could" weigh an ounce in which case, 16 fluid ounces would weigh a pound, but depending on the weight of the substance you're measuring, it could also weigh more or less than a pound. Gasoline, oil, water, blood, mercury, etc. all have different weights per ounce of volume, so all would weigh more or less than a pound. What confuses many folks, though, is that water weighs approximately 8.34 pounds per gallon, which works out to slightly more than an ounce (weight) per fluid ounce. When the weight of water is rounded off to 8 pounds per gallon, it works out to be exactly one ounce per fluid ounce...and that confuses many people. Hope that helps.

IF IT IS LABELED---16 FLUID OUNCES IT IS ALSO 1 POUND----IF IT IS A PRODUCT THAT IS NOT 1 POUND IT IS LABELED AS SIMPLY A VOLUME OF LIQUID----FOR EXAMPLE A PINT OF MERCURY WOULD NOT BE LABELED AS ANY PARTICULAR NO OF FLUID OUNCES--ONLY AS 1 PINT---ONLY THOSE PRODUCTS THAT WEIGH 1 POUND PER PINT WILL BE LABELED IN FLUID OUNCES----SO WHATEVER THE FLUID OUNCES---SIMPLY DIVIDE BY 16 TO FIND THE WEIGHT----EXAMPLE---40 FLUID OUNCES WILL WEIGH 2-1/2 POUNDS REGARDLESS OF THE PRODUCT--OTHERWISE IT WILL NOT BE LABELED IN FLUID OUNCES. -----SUBMITTED BY travellingdittohead@yahoo.com
