Convert ounces (oz) to pounds (lbs) and back. Mixed lbs+oz format, fraction display, grams, kilograms, pound progress bars, and everyday weight comparison.
There are 16 ounces in a pound, so ounce-to-pound conversion is the quickest way to move between small package weights and the larger unit used for groceries, shipping, and body weight. It is especially useful when a scale reports ounces but you want a cleaner pound value. The same ratio also shows up in food labeling and mailing thresholds, so a fast conversion can save time whether you are packing a parcel or portioning ingredients.
This converter handles both directions and shows decimal pounds, lb+oz format, fractions, grams, kilograms, and stones. The progress bars and comparison table make it easier to understand partial-pound values such as 20 oz, 26 oz, or 40 oz without doing the mental grouping yourself. It also gives you a quick cross-check for amounts that are close to a pound but not quite there, which is where manual rounding usually goes wrong.
Use it when you need a direct oz-to-lb answer plus the common companion formats in the same place. The extra unit views are there so the result can move straight into a label, recipe, or shipping form without another conversion step.
The basic ratio is simple, but real-world weights are often awkward fractions of a pound. This converter turns ounces into decimal pounds, mixed pounds and ounces, and metric units so you can use the result on labels, recipes, or shipping forms immediately. It also helps when you need to compare a measured amount with a cutoff weight and do not want to guess at the missing ounces.
pounds = ounces ÷ 16 ounces = pounds × 16 1 oz = 28.3495 g = 0.0283495 kg
Result: 1.5 lbs = 1 lb 8 oz ≈ 1 ½ lb
24 oz ÷ 16 = 1.5 pounds. Mixed: 1 lb 8 oz. Metric: 680.4 g = 0.680 kg. About the weight of a hardcover book.
The avoirdupois system (used in the US and UK for everyday weight) was designed for trade in the 13th century. 16 was chosen because it divides evenly by 2, 4, and 8 — making it easy to split goods into halves, quarters, and eighths without fractions. This is why we have standard package sizes of 8 oz, 4 oz, and 2 oz.
US recipes specify meat and cheese in ounces: a serving of chicken is 4 oz (¼ lb), a steak might be 8–16 oz. Understanding ounce-to-pound conversion helps with grocery shopping (buying "1.5 lbs" when you need 24 oz) and meal prep portioning.
USPS First Class Mail rates increase per ounce. UPS and FedEx round up to the nearest pound for billing. Knowing your package weight in both ounces and pounds ensures you choose the cheapest shipping option.
16 ounces. That is the fixed avoirdupois ratio used for everyday weight in the US.
8 ounces. A quarter pound is 4 ounces and three-quarters of a pound is 12 ounces, so the common fractions are easy to spot.
28.3495 grams. That is the standard avoirdupois ounce used for food, shipping, and general weight conversion.
oz (ounce) measures weight, while fl oz (fluid ounce) measures volume. They are numerically equal only for water-like cases, so the unit label matters.
No. A troy ounce for precious metals is 31.103 g, while a standard avoirdupois ounce is 28.350 g. They are close enough to confuse people, but they are not interchangeable.
Divide by 16 to get pounds. Multiply the remainder by 16 for the ounces part, so 26 oz becomes 1 lb 10 oz.
