The short answer
454 grams = 16.01 ounces (16.0144 to four places). That is 1 pound and 0.01 ounce, so for every kitchen purpose 454 g is one pound, or 16 ounces.
The exact pound is 453.59237 g. Packages round it up to 454 g, which is why a one-pound bag, tub or box shows 454 g in the metric part of its label.

The formula
Ounces = grams ÷ 28.349523125. Pounds = grams ÷ 453.59237. Both divisors are exact by definition: one avoirdupois pound is 0.45359237 kg, and one pound is 16 ounces.
So 454 ÷ 28.349523125 = 16.0144 oz, and 454 ÷ 453.59237 = 1.0009 lb. For a cup measure, divide the grams by the ingredient’s weight per cup instead: 454 ÷ 200 = 2.27 cups of granulated sugar.
Common package weights
US packages are sold in pounds and ounces and also print the metric weight. These are the exact gram figures behind the most common sizes.
| US package | Exact grams | Ounces |
|---|---|---|
| 1/4 lb | 113.4 | 4 oz |
| 1/2 lb | 226.8 | 8 oz |
| 3/4 lb (12 oz) | 340.2 | 12 oz |
| 1 lb | 453.6 | 16 oz |
| 1 1/2 lb | 680.4 | 24 oz |
| 2 lb | 907.2 | 32 oz |
| 5 lb | 2268 | 80 oz |
Going the other way, metric packages from Europe and elsewhere are sold in round grams. This table gives their weight in ounces and pounds.
| Grams | Ounces | Pounds |
|---|---|---|
| 100 g | 3.53 | 0.22 |
| 113 g | 3.99 | 0.249 |
| 125 g | 4.41 | 0.276 |
| 200 g | 7.05 | 0.441 |
| 227 g | 8.01 | 0.5 |
| 250 g | 8.82 | 0.551 |

Ounces here are avoirdupois ounces of weight, 28.349523125 g each.
Worked examples
A US recipe calls for 1 lb of butter and you buy 250 g blocks. You need 454 g. Use one full block and 204 g of the second. With tablespoon marks, 204 g is 14.4 tablespoons.
A bread recipe asks for 500 g of flour and you have a 1 lb bag. The bag holds 454 g, so you are 46 g short. At 7.5 g per tablespoon of all-purpose flour that is about 6 tablespoons, a little more than 1/3 cup.
454 g of granulated sugar in cups. 454 ÷ 200 = 2.27 cups. Measure 2 1/4 cups + 1 tsp.
Weight ounces and fluid ounces
The ounces on this page are ounces of weight. A fluid ounce is a volume, 29.57 ml. The two match only for water and similar liquids: 454 g of water is about 15.3 US fluid ounces, while 454 g of honey is only about 10.7 fluid ounces, because honey is denser.
When a label says “16 oz (454 g)” for a dry food such as flour, sugar or pasta, it is always weight. US labelling rules require the net quantity in both US and metric units, and the metric number is the same weight rounded.
