Frequently asked questions
Why are there 16 ounces in a pound instead of 10?
The pound system predates decimal measurement. The 16-ounce pound comes from the English trade pound, standardized in the medieval period. It has the practical advantage that it divides evenly into halves, quarters, eighths, and sixteenths, which made fractions convenient before calculators.
Is a troy ounce the same as a regular ounce?
No. The troy ounce (31.1035 grams) is heavier than the avoirdupois ounce (28.3495 grams). Troy ounces are used for precious metals (gold, silver, platinum). When you see gold prices quoted per ounce, those are troy ounces. This converter uses avoirdupois ounces for everyday weight conversion.
How many ounces is a pound of butter?
Exactly 16 ounces. A standard US stick of butter is 4 oz or 1/4 lb. A pound of butter contains 4 sticks.
What is 12 ounces in pounds?
12 / 16 = 0.75 pounds, or three-quarters of a pound. This is a common weight for a can of beer (12 fl oz of water weighs about 12.5 oz by weight) and for standard can goods.
