Sweetener Conversion Calculator
How much monk fruit or stevia replaces a cup of sugar?
Switching from sugar to a zero-calorie sweetener can cut hundreds of calories per recipe — but getting the conversion right matters. Pure monk fruit extract is 150–200× sweeter than sucrose, according to the FDA's GRAS determinations, while stevia's Rebaudioside A reaches 200–350× sugar's sweetness per the European Food Safety Authority (EFSA). Bulk sweeteners like erythritol and allulose sit closer to sugar's sweetness at roughly 70%, as documented in the International Journal of Food Sciences and Nutrition. Use the calculator below to instantly convert any sugar amount — in grams, teaspoons, or cups — into the precise equivalent for six popular alternatives. Each result factors in sweetness intensity and includes practical baking notes so your recipes turn out right the first time.

Sweetener Profiles & Baking Notes
Pure Monk Fruit Extract
Sweetness: 150–200× sugar
Calories: 0
Glycemic Index: 0
Baking: No bulk or browning. Blend with erythritol (typical ratio: ¼ tsp extract + 1 cup erythritol per 1 cup sugar).
Stevia (Reb A)
Sweetness: 200–350× sugar
Calories: 0
Glycemic Index: 0
Baking: No caramelization. Can have bitter aftertaste at high concentrations. Reb M has less bitterness than Reb A.
Erythritol
Sweetness: 70% of sugar
Calories: ~0.2 cal/g
Glycemic Index: 0
Baking: Good bulk and structure. May crystallize when cooled. Dissolves well when heated. No significant GI side effects at moderate doses.
Allulose
Sweetness: 70% of sugar
Calories: ~0.4 cal/g
Glycemic Index: 0
Baking: Best sugar mimic — browns, caramelizes, retains moisture. FDA excludes it from "total sugars" and "added sugars" on labels.
Xylitol
Sweetness: 1:1 with sugar
Calories: 2.4 cal/g
Glycemic Index: 7
Baking: Direct 1:1 swap. Browns slightly. Warning: Extremely toxic to dogs — keep away from pets.
Sucralose
Sweetness: 600× sugar
Calories: 0
Glycemic Index: 0
Baking: Heat-stable up to 450°F. No bulk — use with a bulking agent. Splenda granulated includes maltodextrin for volume.
