converting Freon from pounds to ounce

How do I calculate the amount of ounces of Freon in a pound?
Is is the same as water 16 ounces in a pound

Ounce has multiple meaning. As a unit of weight, the avoirdupois ounce is 1/16 of a pound, no matter what is being weighed. I am guessing that is the ounce you mean.

Then the is the fluid ounce, used in measuring the volume of liquids. There are 16 fluid ounces per pint. 1 fl oz of water is NOT 1 av oz of water, although it fairly close.

Then there is the troy ounce used in measuring gold and other precious metals. It is a different size than the av. oz., and there are 12 troy ounces in a troy pound.

(and they say metric is hard )

Re: converting Freon from pounds to ounce

JohnS is correct. There is a difference between fluid ounces and ounces [weight]. Here's an example

Fresh water weighs approximately 8.33 pounds (108.29 ounces) per gallon (128 fluid ounces). If you divide 108.29 by 128 you find that fresh water weighs 0.84 ounces/fluid ounce.

Sea water weighs approximately 8.6 pounds (137.6 ounces) per gallon (128 ounces). Using the same equation you discover that sea water weighs 1.075 ounces/fluid ounce.

Apply that to freon which has a specific gravity of 1.21 in liquid form. This means it weighs 1.21 times more than water (which has a specific gravity of 1) within the same volume. So if we multiply 0.84 (the weight of fresh water/fluid ounce) by 1.21 you discover that 1 fluid ounce of freon weighs approximately 1 ounce.

Hope this helps.
