These days, two different types of ounces remain in common use:

Ho to Convert Oz to Lbs?Ounces are typically found in recipes, cookbooks etc. in countries which use the imperial system of measurement informally, e.g. UK, or officially such as in the US systems of measurement.
In these countries, the (international avoirdupois) pound, defined as 0.45359237 kg is the key unit of mass, serving for the same purpose as ounces in retail sale for grocery products.
To convert oz to lbs you simply divide the mass in oz by 16 to obtain the equivalent in pounds.
The oz into lbs formula is: [lb] = [oz] / 16.
This means that one ounce is 0.0625 lbs.

Troy Ounce to PoundYou already know how to conduct the oz to lbs conversion for the unit avoirdupois units, so we are left with how to change troy weights used to determine the mass of precious metals.
For the sake of disambiguation, for the troy weight system, used to measure gold, silver and platinum for example, we use the symbol oz t and lb t, respectively.
To change troy ounces to troy pounds you would use this formula: [lb t] = [oz t] / 12, yet the troy pound is a legacy unit long abolished in trade and general use.
Which means, that you are probably looking for troy ounces to pounds: [lb] = [oz t] × 12 / 175.
In contrast to the avoirdupois system, in which one ounce equals 1/16 pounds, in the troy weight system the mass of one ounce is equivalent to 1/12 pounds.
Both, the avoirdupois as well as the troy ounce are based on the unit grain, a measurement of mass, defined as 0.06479891 grams.
However, one oz contains 437.5 grains, whereas the oz t comprises of 480 grains.
Therefore, the troy ounce is approximately 10% heavier than the avoirdupois ounce.
Assumed you have 18 ounces (oz t) of gold, then this mass is equivalent to 559.8625824 grams, equal to 1.5 troy pounds and approximately 1.23 avoirdupois pounds.
So as to change the other units between the two systems use these formulas:
- Troy ounce to ounce: [oz] = [oz t] × 192 / 175
- Troy pounds to pounds: [lb] = [lb t] × 144 / 175
