How to measure Maple syrup by volume
- Measure in a liquid cup at eye level, or weigh it straight into the bowl.
- Lightly oiling the cup helps the syrup release completely.
- “Pancake syrup” (corn-syrup based) is a different product; it runs slightly heavier per cup.
Why the weight varies
Pure maple syrup varies only slightly with grade and temperature; table (pancake) syrup blends can weigh a little more.
Maple syrup is about a third water, so swapping it for sugar changes a recipe’s liquid balance — most conversions reduce other liquids by roughly 3 tablespoons per cup of syrup. Weight-accurate substitution starts with the correct 315 g figure.
Which value we publish, and why
We publish 315 g per US cup (USDA FoodData Central); King Arthur’s 156 g per ½ cup scales to 312 g.
