1 cup maple syrup = 322 grams
Volume is only half the story. Maple syrup weighs 322 g per US cup (liquid), so we convert with a tested, ingredient-specific factor instead of a generic table.

Why maple syrup conversions vary
Pure maple syrup weighs about 322 g per US cup, noticeably denser than water and slightly lighter than honey. When a recipe trades syrup for granulated sugar, use about 3/4 cup of syrup for each cup of sugar and reduce the liquid elsewhere by a few tablespoons. Pancake-topping amounts never need precision; candy making does.
Our factor for maple syrup — 322 g per US cup — comes from USDA FoodData Central. Weighing beats measuring cups for repeatability: a scale gives the same result every time regardless of how the ingredient settled, and it scales recipes cleanly. Note that a US cup (236.6 ml) and a metric cup (250 ml) are not the same; recipes from outside North America may assume the metric size, which shifts every weight by about five percent.
The table below lists the amounts bakers actually reach for — quarters, thirds, and halves of a cup through three full cups — computed directly from the factor above. The converter handles any other amount instantly and uses the exact same number, so the quick reference and the live result can never drift apart.
Frequently asked questions
How much does 1 cup of maple syrup weigh?
One US cup of maple syrup weighs 322 g (liquid). This comes from USDA FoodData Central.
Why do some recipes list a different weight for maple syrup?
Measuring conventions and brands differ, and packing changes the weight. We state our convention openly; when a recipe names its own gram value, follow that one for best results.
Should I measure maple syrup by cups or by weight?
Weight, whenever the recipe allows. Grade and color describe flavor, not density — all pure maple syrup weighs about the same per cup.
