Ounces to Pounds Formulas

• Definition: 1 pound (lb) = 16 ounces (oz)
• Pounds from ounces: lb = oz ÷ 16
• Ounces from pounds: oz = lb × 16
• Split into lb and oz: lb = floor(oz ÷ 16); oz left = oz − 16 × lb
• Metric: 1 oz = 28.349523125 g; 1 lb = 453.59237 g

Key Terms

• Ounce (oz): one sixteenth of a pound, 28.35 g.
• Pound (lb): 16 ounces, 0.45359237 kg exactly.
• Avoirdupois: the everyday system of weights for goods and food.
• Troy ounce: 31.10 g; 12 make a troy pound.
• Fluid ounce: a unit of volume, not weight.

Worked Example

A newborn weighs 118 ounces. What is that in pounds and ounces?

• 118 ÷ 16 = 7.375 lb
• Whole pounds: 7; 7 × 16 = 112 oz, so 118 − 112 = 6 oz left over
• So the baby weighs 7 lb 6 oz, or 3,345 g.

Going the other way, a 2.25 lb pack of chicken is 2.25 × 16 = 36 oz.

Real-Life Examples

• Babies: turn a weight in ounces into pounds and ounces.
• Shipping: carriers price by the pound; 20 oz rounds up to 2 lb.
• Cooking: a 12 oz steak is 0.75 lb.
• Fishing: log a 76 oz catch as 4 lb 12 oz.

Decimal Pounds vs Pounds and Ounces

Scales and shipping systems often show weight as decimal pounds, such as 2.375 lb, while people talk about pounds and ounces, such as 2 lb 6 oz. The two are the same weight written differently: the decimal part is a fraction of a pound, not a number of ounces. Multiply the decimal part by 16 to get ounces (0.375 × 16 = 6). Reading 2.375 lb as 2 lb 3.75 oz is one of the most common mistakes in kitchens and mailrooms.

The ounce used here is the avoirdupois ounce for everyday goods. Liquids sold in fluid ounces are measured by volume, so 16 fl oz of a drink is a pint, not a pound, although 16 fl oz of water happens to weigh about 1.04 lb. Precious metals use the troy system, where a troy pound has only 12 troy ounces.

Common Mistakes to Avoid

• Reading decimals as ounces. 1.5 lb is 1 lb 8 oz, not 1 lb 5 oz.
• Using 10 ounces per pound. There are 16.
• Mixing fluid and weight ounces. 16 fl oz is a pint, not a pound.
• Using troy ounces for food. Troy is only for precious metals.
• Forgetting carriers round up. 16.1 oz is billed as 2 lb.
