Convert cups to grams for common cooking ingredients. Ingredient-specific density factors for flour, sugar, butter, rice, oats, and more.
Converting cups to grams requires knowing the ingredient's density, because different ingredients weigh different amounts per cup. One cup of flour weighs about 125 grams, while one cup of sugar weighs about 200 grams, and one cup of butter weighs about 227 grams.
This converter includes density factors for the most common baking and cooking ingredients. Select your ingredient, enter the number of cups, and get an accurate gram weight. This is far more precise than volume measurements alone.
Professional bakers and international recipes prefer weight measurements (grams) over volume (cups) because weight is consistent regardless of how you scoop or pack the ingredient. Use this tool to convert any American cup-based recipe to gram weights.
This measurement provides a critical foundation for goal setting and progress tracking, helping you align daily activities with longer-term objectives and meaningful milestones. Integrating this calculation into regular planning habits ensures that work priorities reflect actual data about where time and energy produce the greatest results each week.
Volume measurements for dry ingredients are imprecise — a "cup of flour" can vary by 30% depending on how it's scooped. Converting to grams ensures consistent, repeatable results. This matters most in baking where precision affects texture and rise. Having accurate figures readily available simplifies project planning, deadline negotiation, and workload balancing conversations with managers, clients, and team members.
grams = cups × density_factor Common density factors (grams per cup): All-purpose flour: 125 g Granulated sugar: 200 g Brown sugar (packed): 220 g Powdered sugar: 120 g Butter: 227 g Water/Milk: 237 g Honey: 340 g Rice (uncooked): 185 g Oats (rolled): 90 g Cocoa powder: 86 g
Result: 312.5 g
2.5 cups × 125 g/cup = 312.5 grams. This is the weight of 2.5 cups of all-purpose flour using the spoon-and-level method. Scooping directly from the bag may yield 140–150 g per cup.
A cup of flour can weigh anywhere from 120 to 155 grams depending on whether it was spooned, scooped, sifted, or packed. This 30% variation is enough to ruin a delicate cake or pastry. Professional bakers and most international recipes use weight measurements to avoid this inconsistency.
Flour is light and airy (125 g/cup), granulated sugar is crystalline and dense (200 g/cup), brown sugar is packed (220 g/cup), and butter is a solid fat (227 g/cup). Cocoa powder is particularly light at 86 g/cup. Each ingredient needs its own conversion factor.
A basic digital kitchen scale costs $10–15 and measures in both grams and ounces. Once you start baking by weight, you will never go back to cups. Many bakers zero (tare) the scale between ingredients, adding directly to the mixing bowl.
One cup of all-purpose flour weighs approximately 125 grams when measured using the spoon-and-level method. If you scoop the cup directly into the flour bag, it can weigh 140–150 grams due to compaction.
Different ingredients have different densities. Sugar crystals are denser and heavier per cup than fluffy flour. Butter is a solid fat with yet another density. Volume does not account for these differences, which is why weight is more precise for cooking.
No. One cup of granulated sugar weighs about 200 grams, while one cup of all-purpose flour weighs about 125 grams. Sugar is significantly denser than flour, which is why weight measurements are preferred for precision.
One US cup of butter weighs 227 grams, which is exactly 2 sticks of butter (each stick is 113.5 g or 1/2 cup). A tablespoon of butter is about 14.2 grams.
Yes. Water and milk weigh approximately 237 grams per US cup (based on a density close to 1 g/mL and 236.588 mL per cup). Heavier liquids like honey weigh about 340 g per cup.
Weight measurements are consistent and repeatable regardless of how you scoop, pack, or sift the ingredient. A cup of flour can vary by 30% depending on technique. Grams eliminate this variability, producing more reliable baking results every time.
