Results use the documented ingredient state and one US customary cup.
Divide the gram amount by 312 to calculate US cups. The practical fraction is a measuring aid, not a replacement for the exact gram weight.
| Grams | US cups | Practical reference |
|---|---|---|
| 25 g | 0.08 cups | about 1/8 cup |
| 30 g | 0.10 cups | about 1/8 cup |
| 40 g | 0.13 cups | about 1/8 cup |
| 50 g | 0.16 cups | about 1/8 cup |
| 60 g | 0.19 cups | about 1/4 cup |
| 75 g | 0.24 cups | about 1/4 cup |
| 80 g | 0.26 cups | about 1/4 cup |
| 100 g | 0.32 cups | about 1/3 cup |
| 120 g | 0.38 cups | about 1/3 cup |
| 125 g | 0.40 cups | about 1/3 cup |
| 150 g | 0.48 cups | about 1/2 cup |
| 200 g | 0.64 cups | about 2/3 cup |
| 250 g | 0.80 cups | about 3/4 cup |
| 300 g | 0.96 cups | about 1 cup |
| 400 g | 1.28 cups | about 1 1/4 cups |
| 500 g | 1.60 cups | about 1 2/3 cups |
Pour into a liquid measuring cup on a level surface and read at eye level. Oiling the cup first makes the syrup release cleanly, though weighing it directly into the bowl avoids the problem entirely.
Grams = cups × 312
One cup is 312 grams, one-half cup is about 156 grams and one-quarter cup is about 78 grams.
Common uses
- Oatmeal and overnight oats
- Granola
- Cookies and crumble toppings
Liquid sweeteners sit in a narrow weight band but behave differently in baking. Swapping between them changes moisture and browning as well as sweetness.
| Type | Grams per US cup | What changes |
|---|---|---|
| Maple syrup | 312 g | The reference on this page. |
| Honey | 340 g | Heavier and sweeter per gram. |
| Golden syrup | 340 g | Matches honey. |
| Corn syrup | 328 g | Less sweet, used for texture. |
| Agave nectar | 328 g | Sweeter than maple, so less is needed. |
| Molasses | 337 g | Strong flavour, similar weight. |
Replacing granulated sugar with maple syrup means removing liquid elsewhere: syrup is roughly a third water, which a dry sugar is not.
Comparison figures are typical published US baking references. Only the maple syrup value above is part of this site's sourced dataset.
Pancake syrups blended with corn syrup weigh slightly more. The value on this page names the exact product state it applies to, so you can check it against your own ingredient rather than trusting a bare number.
The converter does not assume that every cup weighs 237 or 250 grams. It uses the documented value for the exact ingredient and state selected.
If a product label or recipe publisher supplies a different gram weight for one cup, follow that recipe-specific value for the closest match to the original testing.
