Oz to Pounds (oz to lb)
26 oz × 0.0625 = 1.625 lb
As pounds and oz: 1 lb 10 oz
One pound equals 16 oz exactly, so to convert oz to pounds you divide by 16. That means 8 oz is 0.5 lb, 24 oz is 1.5 lb, and 32 oz is 2 lb. Going the other way, multiply pounds by 16: 3 lb is 48 oz. The factor is exact, not rounded, because the oz is defined as one sixteenth of a pound.
These are units of mass, not volume. The oz here is the avoirdupois oz used for body weight, food packaging, and postage, weighing 28.3495 grams. It is not the fluid oz, which measures liquid volume. The converter also handles kilograms and grams, since 1 kg = 2.20462 lb = 35.274 oz, and it prints results as a lb + oz composite as well as a decimal.
How many oz are in a pound?
There are 16 oz in a pound. This is a definition rather than a measurement, so there is no rounding error to worry about: 1 lb = 16 oz, and 1 oz = 0.0625 lb. Half a pound is 8 oz, a quarter pound is 4 oz, and the quarter-pound burger patty is exactly that, 4 oz (113.4 g) of raw meat.
The relationship holds for the pound used in the United States and the United Kingdom alike, because both use the international avoirdupois pound of 453.59237 grams. Divide that by 16 and you get 28.3495 grams per oz. If you ever see an oz that is not a sixteenth of a pound, you are looking at a troy oz, which belongs to a different system used for precious metals.
How to convert oz to pounds
Divide the number of oz by 16. For 56 oz: 56 ÷ 16 = 3.5 lb. To reverse it, multiply pounds by 16, so 3.5 lb × 16 = 56 oz. Because 16 is a power of two, you can also halve repeatedly: halving oz four times gives pounds, and 64 oz halved to 32, 16, 8, then 4 lands on 4 lb. To reach kilograms instead, divide oz by 35.274, or divide pounds by 2.20462.
- Take your figure in oz.
- Divide by 16 to get pounds. Example: 40 oz ÷ 16 = 2.5 lb.
- For a lb + oz reading, keep the whole pounds and multiply the leftover decimal by 16: 2.5 lb becomes 2 lb 8 oz.
What is an oz?
The oz (oz) is a unit of mass equal to 28.3495 grams, defined as one sixteenth of the avoirdupois pound. It is the standard small weight unit in the United States for food labels, letter mail, and retail packaging. A slice of bread is around 1 oz (28 g), a standard tin of beans is often 15 oz (425 g), and a letter can be posted at the base rate up to 1 oz.
The avoirdupois oz should not be mixed up with two other units that share the name. The fluid oz measures volume, roughly 29.5735 mL, and a fluid oz of water weighs about 1.04 oz while a fluid oz of oil weighs less, so they are never interchangeable. The troy oz, at 31.1035 grams, is used only for gold, silver, and other precious metals.
What is a pound?
The pound (lb) is a unit of mass equal to exactly 453.59237 grams, or 16 oz. The abbreviation lb comes from the Latin libra. It is the main unit of body weight and grocery weight in the United States, and it remains in everyday use in the United Kingdom alongside the kilogram, particularly for personal weight and for babies.
The kilogram is the metric counterpart and the base unit of mass in the SI system, defined through the Planck constant rather than a physical object. One kilogram equals 2.20462 lb or 35.274 oz, and one gram is a thousandth of a kilogram. Because the converter offers kg and g as extra units, you can move a figure from oz straight to metric: 80 oz is 5 lb, which is 2.268 kg (2268 g).
Pounds and oz together: the composite result
This converter prints a lb + oz composite as well as a decimal. Enter 26 oz and it returns 1 lb 10 oz, not just 1.625 lb. That is the form people actually use, and a decimal pound is often useless to them. Nobody says a package weighs 1.625 pounds; the label says 1 lb 10 oz.
The arithmetic is a division with a remainder. Divide the oz by 16 to get the whole pounds, and whatever is left over is the oz. For 26 oz: 26 ÷ 16 = 1 remainder 10, so the answer is 1 lb 10 oz. For 100 oz: 100 ÷ 16 = 6 remainder 4, so 6 lb 4 oz. Starting from a decimal instead, take the fractional part and multiply it by 16, the 0.625 in 1.625 lb becomes 0.625 × 16 = 10 oz.
Two cases make this a daily need. Birth weights are quoted in pounds and oz, so a newborn is 7 lb 4 oz, never 7.25 lb, and a parent converting a hospital reading of 3.29 kg wants 7 lb 4 oz back. Shipping is the other: carriers price parcels in pounds and oz, and a 26 oz box is booked and labelled as 1 lb 10 oz. In both cases the composite is the answer and the decimal is an intermediate step.

Frequently asked questions
16 oz. The oz is defined as one sixteenth of a pound, so 1 lb = 16 oz exactly and 1 oz = 0.0625 lb.
24 oz = 1.5 lb, because 24 ÷ 16 = 1.5. As a composite that is 1 lb 8 oz, and in metric it is 680.4 g (0.68 kg).
1.5 lb = 1 lb 8 oz. Keep the whole pound, then multiply the decimal part by 16: 0.5 × 16 = 8 oz.
Because an oz is a fine enough step to track a newborn's daily gain or loss, which a decimal pound obscures. A birth weight is quoted as 7 lb 4 oz (3.29 kg) rather than 7.25 lb, and hospitals in the US and UK both record it that way.
1 kg = 35.274 oz, which is 2.20462 lb, or 2 lb 3.3 oz as a composite. Going back, 1 lb = 0.453592 kg and 1 oz = 28.3495 g.
Yes, for the avoirdupois pound used in the US, the UK, and Canada, all of them use the international pound of 453.59237 g, so all of them have 16 oz to the pound. The exception is the troy system, where the pound has 12 troy oz.
A troy pound is 12 troy oz (373.24 g) and is used only for precious metals; an avoirdupois pound is 16 oz (453.59 g) and is used for everything else. A troy oz is also heavier than a regular oz, at 31.1035 g against 28.3495 g.
No. The oz here measures mass (28.3495 g); the fluid oz measures volume (29.5735 mL). A recipe asking for 8 oz of flour and one asking for 8 fl oz of milk are asking for different things, and this converter handles only the weight oz.
32 oz = 2 lb exactly, since 32 ÷ 16 = 2. That is 907.18 g, or a little over 0.9 kg.
Divide the oz by 35.274. For example, 100 oz ÷ 35.274 = 2.835 kg. You can also go through pounds: 100 oz = 6.25 lb, and 6.25 ÷ 2.20462 = 2.835 kg.
