Why You Might Need This Conversion
There are several everyday reasons to know how many grams are in a pound:

What About Ounces?
Sometimes you’ll need to work with ounces (oz) as well. Here’s how the full breakdown works:
- 1 lb = 16 oz
- 1 oz = 28.35 g
- 16 oz × 28.35 = 453.6 g
So if your recipe lists something in ounces, you can use:
Grams = Ounces × 28.35
Or to go from grams to ounces:
Ounces = Grams ÷ 28.35
