Ounces to Pounds Conversion

Converting ounces (oz) to pounds (lbs) is a standard calculation in the US for food portions, postal items, and newborn baby weights.

The 16 Rule

The most important number to remember is 16. There are exactly 16 ounces in one pound. This makes the math straightforward if the numbers align, but fractions can be tricky.

Formula: Pounds = Ounces / 16

Detailed Conversion Chart

4 oz = 0.25 lbs (Quarter pound)
8 oz = 0.5 lbs (Half pound)
12 oz = 0.75 lbs (Three-quarter pound)
16 oz = 1 lb
24 oz = 1.5 lbs
32 oz = 2 lbs
48 oz = 3 lbs

Practical Applications

Kitchen Measurements: Many recipes value precision. '8 ounces of cheddar cheese' is exactly half a pound block.

Postal Service: Letters are weighed in oz. A standard letter must be under 1 oz to use a single stamp. Packages over 16 oz (1 lb) usually jump to a different pricing tier.

Baby Weight: Newborns are measured in lbs and oz. A baby weighing "7 lbs 8 oz" is actually 7.5 lbs.

Fluid vs. Dry Ounces (Important!)

This calculator converts weight (dry ounces) to pounds. Do not confuse this with fluid ounces (fl oz), which measure volume. While "a pint's a pound the world around" (16 fl oz ≈ 1 lb), this only holds true for water and similar liquids. Honey, for instance, is much heavier.
