Radishes are a crisp, peppery root vegetable often used in salads, slaws, and as a crunchy snack. While they are low in calories, they do contain a small amount of natural sugar — about 1.9 grams per 100 grams. This Radish Sugar Calculator helps you quickly determine the sugar content in any serving size of raw radishes, whether you're tracking your daily carbohydrate intake, managing blood sugar levels, or simply curious about the nutritional profile of this vegetable.
Perfect for meal planners, diabetics, keto dieters, and health-conscious individuals, this tool provides accurate sugar estimates based on weight or serving count. Simply enter the number of radishes or the weight in grams, and the calculator will return the total sugar content. You can also adjust for different serving sizes using the unit selector. Use the preset buttons for common serving sizes to get instant results.

How to Use This Tool
Using the Radish Sugar Calculator is straightforward. Start by entering the amount of radishes you want to evaluate. You can type a number directly into the input field or click one of the preset buttons (e.g., 50 g, 1 radish) for quick common servings. Next, select the appropriate unit from the dropdown: grams (g), ounces (oz), or number of medium radishes. The calculator assumes a medium radish weighs about 7 grams. Click the blue Calculate Sugar button to see the total sugar content in grams, ounces, and teaspoons of sugar. Use the Reset button to clear the results and start over.
💡 Tip: For the most accurate results, weigh your radishes on a kitchen scale and enter the weight in grams. The preset buttons are convenient estimates but may vary depending on the actual size of your radishes.
Formula Explained
The calculation is based on the standard nutritional data for raw radishes: approximately 1.9 grams of sugar per 100 grams of radish. The formula is:
Sugar (g) = (Weight of radish in grams) × (1.9 / 100)
If you enter the amount in ounces, the tool first converts ounces to grams (1 oz = 28.3495 g). If you enter the number of radishes, it multiplies by the average weight of a medium radish (7 g) to get the total weight in grams, then applies the sugar ratio. The result is also converted to teaspoons (1 tsp sugar ≈ 4.2 g) for a more intuitive reference.
Worked Examples
Example 1: You have 3 medium radishes. Enter 3 and select radishes (medium). The calculator computes: 3 × 7 g = 21 g total weight. Sugar = 21 × (1.9/100) = 0.40 g. That's about 0.095 teaspoons of sugar — a negligible amount.
Example 2: You want to know the sugar in 150 g of sliced radishes for a salad. Enter 150 and select grams (g). Sugar = 150 × (1.9/100) = 2.85 g. That's roughly 0.68 teaspoons of sugar.
Example 3: A recipe calls for 4 oz of radishes. Enter 4 and select ounces (oz). The tool converts: 4 × 28.3495 = 113.4 g. Sugar = 113.4 × (1.9/100) = 2.15 g.
Factors Affecting Accuracy
The sugar content of radishes can vary slightly depending on the variety (e.g., red globe, daikon, black radish), growing conditions, and freshness. The value of 1.9 g per 100 g is an average for raw red radishes from the USDA National Nutrient Database. Daikon radishes, for example, have a slightly lower sugar content (about 1.5 g per 100 g). If you are using a different variety, consider adjusting the sugar density manually. The average weight of a medium radish (7 g) is also an estimate; actual weights can range from 5 g to 15 g. For precise tracking, always weigh your radishes.
Frequently Asked Questions
Q: Are radishes high in sugar?
A: No. Radishes are very low in sugar compared to most fruits and many vegetables. A 100 g serving (about 14 medium radishes) contains only 1.9 g of sugar, which is less than half a teaspoon. They are an excellent choice for low-sugar and low-carb diets.
Q: Can I use this calculator for cooked radishes?
A: Cooking can slightly concentrate the sugar content as water evaporates, but the change is minimal. For cooked radishes, the sugar per 100 g may be slightly higher. This calculator is designed for raw radishes. If you need data for cooked radishes, refer to a specific nutritional database.
Q: How does radish sugar compare to other vegetables?
A: Radishes have less sugar than carrots (4.7 g/100g), beets (6.8 g/100g), and peas (5.9 g/100g), but more than leafy greens like spinach (0.4 g/100g) or lettuce (0.8 g/100g). They are a moderate-low sugar vegetable.
Q: Is radish sugar natural or added?
A: All sugar in raw radishes is naturally occurring — primarily glucose and fructose. There are no added sugars.
