How to convert ounces to pounds
Divide the ounces by 16. That one step gives you decimal pounds, because 16 ounces make a pound. So 8 oz is 0.5 lb, 24 oz is 1.5 lb, and 100 oz is 6.25 lb.
To write the answer as pounds and ounces, keep the whole pounds and turn the rest back into ounces. Take 45 oz. It holds two full pounds (32 oz) and 13 oz are left over, so 45 oz is 2 lb 13 oz. The result card shows both forms at once.
To go the other way, multiply by 16. A weight of 2 lb 13 oz is 2 × 16 + 13 = 45 oz. Use the pounds + ounces tab when a scale or a label gives you both numbers and a form asks for ounces only.
Weight ounces, troy ounces and fluid ounces
The word ounce covers three different units. This converter handles all three, so pick the one that matches your number.
| Unit | What it measures | One ounce equals | In pounds |
|---|---|---|---|
| Weight ounce (oz) | Food, mail and body weight | 28.35 g | 0.0625 lb |
| Troy ounce (ozt) | Gold, silver and platinum | 31.1 g | 0.0686 lb |
| US fluid ounce (fl oz) | Volume of drinks and liquid ingredients | 29.57 mL | 0.0652 lb of water |
A fluid ounce has no fixed weight. One US fluid ounce of water weighs about 1.04 oz, the same volume of honey about 1.5 oz, and olive oil about 0.95 oz.
Pounds and ounces in grams and kilograms
Every result also shows grams and kilograms, since one pound is 453.59237 g and one ounce is 28.349523125 g. This helps with recipes written in metric, parcels that need a weight in kilograms, and newborn weights. A baby of 7 lb 6 oz weighs 118 oz, or about 3.35 kg.
Two mistakes that give wrong answers
The first is reading 1.5 lb as 1 lb 5 oz. The .5 is half a pound, which is 8 oz, not 5 oz. Decimal pounds and ounces use different scales.
The second is treating fluid ounces as weight ounces. 16 fl oz of honey weighs about 1.5 lb, not 1 lb.
How the conversion works
This converter uses the exact definitions from the 1959 international yard and pound agreement. One pound is 453.59237 g and holds 16 ounces, so one ounce is exactly 28.349523125 g. Ounces to pounds is a division by 16, and pounds to ounces is a multiplication by 16. Nothing is estimated. The result is rounded only for display, and you choose how many decimal places to show.
The pounds + ounces tab multiplies your pounds by 16, adds your ounces, and shows the total in ounces, decimal pounds, grams and kilograms. When a result is split into pounds and ounces, the ounces are rounded to two decimals first, so you never see a line like 2 lb 16 oz.
Troy ounces use 31.1034768 g each. Fluid ounces need a liquid. The tool turns fluid ounces into milliliters (29.5735 for a US fluid ounce, 28.4131 for a UK one) and multiplies by the density of the liquid. The densities come from USDA FoodData Central cup weights, with water counted as 1 g per mL. Real liquids vary a little with temperature and brand.
