Peaches are naturally sweet, but the amount of sugar you get depends a lot on how the peach is prepared. A fresh peach contains roughly 8.3 grams of sugar per 100 grams, while dried peaches can pack more than 41 grams — and canned peaches in syrup sit somewhere in between. This Peach Sugar Per 100g Calculator lets you pick a peach type, enter your portion size in grams, and instantly see the total sugar in that portion, along with useful extras like the number of teaspoons of sugar, calories from sugar, and how much of a 50-gram daily added-sugar style limit it uses.
The tool is handy for anyone tracking sugar intake for health, diabetic meal planning, keto-style carb awareness, or just general nutrition curiosity. Because it works from grams, you can use a kitchen scale for accuracy or rely on the quick portion buttons for typical servings like one medium peach or one cup of sliced peaches. All values are based on USDA nutrient data and are rounded to practical figures.

How It Works
This calculator starts with the average sugar content of each peach form per 100 grams. The core calculation is straightforward:
Total sugar (g) = sugar per 100 g × portion weight (g) ÷ 100
From there, it estimates teaspoons by dividing total sugar by 4.2 grams per teaspoon, calories from sugar using 4 kcal per gram of carbohydrate, and a daily-value percentage against a 50-gram reference — a common benchmark for a 2,000-calorie eating pattern. The values are based on entries in USDA FoodData Central for raw peaches, canned peaches in juice, canned peaches in light syrup, and dried peaches.
Step-by-Step Guide
- Choose the peach form that matches what you're eating (fresh, canned in juice, canned in light syrup, or dried).
- Enter the weight of your portion in grams, or use one of the quick portion buttons for a common serving.
- Press Calculate sugar to see the total sugar, teaspoons, calories from sugar, and percentage of the 50 g reference.
- Use the result to compare different peach preparations or log your daily intake.
Reference Data
| Peach form | Sugar per 100 g | Common serving | Sugar in that serving |
|---|---|---|---|
| Raw peach (fresh) | 8.3 g | 1 medium, 150 g | 12.5 g |
| Canned in juice | 11.6 g | 1 cup, 250 g | 29 g |
| Canned in light syrup | 18.2 g | 1 cup, 250 g | 45.5 g |
| Dried (uncooked) | 41.7 g | 1 cup, 160 g | 66.7 g |
Worked Examples
Example 1: one medium fresh peach
150 g of raw peach gives 8.3 × 150 ÷ 100 = 12.5 g sugar, roughly 3 teaspoons and about 50 kcal from sugar.
Example 2: a cup of peaches in light syrup
250 g × 18.2 ÷ 100 = 45.5 g sugar, about 10.8 teaspoons. That's 91% of a 50 g reference, showing how much extra sugar the syrup adds.
Tips & Best Practices
Weigh only the fruit. With canned peaches, the package weight includes the syrup. Drain and weigh the fruit if you want just the peach sugar; the "canned in light syrup" option gives a closer estimate than "in juice" when syrup is present.
Check package labels. Manufacturers can vary syrup density. If a label lists total carbohydrate and fiber, subtracting fiber from total carbs gives you a more exact sugar number for that specific product.
When to Use This
People tracking sugar for diabetes management, low-carb eating, or general nutrition often want to know how sweet a fruit portion really is. This calculator is handy when building a fruit salad, planning a snack, or comparing canned versus fresh options at the grocery store. Because it works in grams, you can scale it to any portion you actually eat.
Limitations
Portion weights are estimates. A medium peach can range from 130 to 170 grams depending on variety, and canned product syrups vary by brand. The teaspoon conversion uses 4.2 g per teaspoon for white sugar; brown sugar and powdered sugar have different densities. Use these figures as practical estimates rather than lab-precise values.
Frequently Asked Questions
Is the sugar in peaches "added" or "natural"?
Fresh peaches contain naturally occurring sugar. Canned peaches in juice or syrup may also contain added sugar, especially in light or heavy syrup. This calculator reports total sugar from the fruit plus any syrup.
Why is dried peach sugar so much higher per 100 g?
Drying removes water, so the sugar becomes more concentrated by weight. A 100 g portion of dried peach represents far more actual peach than 100 g of fresh fruit.
Can I use this for frozen or grilled peaches?
Frozen unsweetened peaches are close to raw values. Grilling doesn't add sugar, but any added honey or glaze will. For those cases, use the raw value and add your own additions.
