Ounces to Grams Converter

Recipes and packs written in ounces lean on fractions, and the input accepts them with a slash. Put a space between the whole ounces and the fraction for mixed amounts:

• ½ oz → type 1/2 → 14.1748 g
• ¼ oz → type 1/4 → 7.0874 g
• ¾ oz → type 3/4 → 21.2621 g
• 1½ oz → type 1 1/2 → 42.5243 g

Decimals give the same answers, so 0.5 and 1/2 are interchangeable. The one thing the field can't read is a pasted ½ or ¾ character, which some recipe sites use. It shows a note that the number couldn't be read; retype the fraction with a slash.

Common pack sizes in ounces convert like this:

A kitchen scale shows whole grams, so round to the nearest gram: 113 g for a 4 oz portion, 227 g for 8 oz. Don't be surprised if a pack labelled in both units prints a slightly different gram figure; labels are rounded too.

For a weight in pounds and ounces, turn it all into ounces first. 1 lb 4 oz is 16 + 4 = 20 oz, which is 566.99 g.

The quick multipliers, checked on 8 oz (226.8 g):

• × 28 gives 224 g, about 1.23% low.
• × 30 gives 240 g, about 5.8% high. That's 13 g of extra sugar in a recipe asking for 8 oz.
• × 30, then take off 5% (the same as × 28.5) gives 228 g, only 0.53% high.

For portioning meat or cheese, × 28 is plenty. For baking, use the converter: small errors in flour, sugar or butter add up across a recipe.

If you convert a whole recipe, convert each ingredient from the original ounces rather than rounding one result and scaling the rest from it.
