Beets are a nutritious root vegetable, but their carbohydrate content varies depending on how they are prepared. This beet carbs per 100g calculator converts any portion — grams, ounces, or cup measures — into a standard per 100g carb value, then scales it to the amount you actually plan to eat. It also breaks out sugars, fiber, and net carbs so you can see the full carbohydrate picture at a glance.
Whether you are counting carbs for diabetes management, following a low-carb or keto eating pattern, or just logging your daily intake, this tool gives you a quick, reliable estimate. Select the beet preparation (raw, boiled, or pickled), enter your portion, check the optional net-carb box, and press Calculate. The result includes both the total carbohydrate content and the per-100g reference numbers.
This calculator is intended for meal planning and education, not as a substitute for professional medical or dietary advice.
Estimate total carbs, sugars, fiber, and net carbs for any beet portion, normalized to a per-100g reference.
How the Carb Calculation Works
Every result starts with a reference value expressed per 100 g, which is the standard used on nutrition labels and in most food databases. The values in this calculator are based on the United States Department of Agriculture's FoodData Central entries for raw, boiled, and pickled beets. For raw beets, the reference figures are approximately 9.56 g total carbohydrate, 6.76 g sugars, and 2.80 g dietary fiber per 100 g. Boiled beets contain slightly more carbohydrate per 100 g because water loss concentrates the nutrients: about 9.96 g total carbs, 7.96 g sugars, and 2.00 g fiber. Pickled beets often include added sugar, which raises the total to roughly 17.5 g carbs per 100 g.
The calculation itself is a simple proportion. If your portion weighs W grams and the preparation has C grams of carbs per 100 g, your portion's carbs are W × C ÷ 100. The same formula is used for sugar and fiber. For net carbs, the fiber value is subtracted from total carbohydrate because fiber is not digested into glucose like other carbs. This number is particularly relevant for ketogenic and low-carb eating, where net carbs are used instead of total carbs. You can pair your beet carb total with a USDA FoodData Central lookup if you want brand-specific or more detailed values.
If you also track calories, the beet calorie calculator can help you estimate the energy side of the same portion.
Step-by-Step Guide
- Choose the beet preparation. Select raw, boiled/drained, or pickled. If you are weighing boiled beets, pick boiled; if you are eating them straight from a jar with brine, choose pickled to account for added sugar.
- Enter the portion size. Type a number in the amount box. You can use grams, ounces, or US cup measures. The cup options use typical density values: 136 g for chopped raw beets and 170 g for sliced beets.
- Adjust the optional net-carb setting. If you follow net-carb or keto tracking, check the box to subtract fiber from total carbs.
- Press Calculate Carbs. The result area shows total carbs for the portion, per-100g carb content, sugars, fiber, and—when selected—net carbs.
- Use the quick-fill buttons to instantly test standard portions like 100 g or 1 cup.
Worked Examples
Example 1: 150 g of raw beet. Total carbs = 150 × 9.56 ÷ 100 = 14.34 g. Fiber = 150 × 2.80 ÷ 100 = 4.20 g. Net carbs = 14.34 − 4.20 = 10.14 g. Sugars = 150 × 6.76 ÷ 100 = 10.14 g.
Example 2: 1 US cup of sliced boiled beets. With the cup conversion set to 170 g, total carbs = 170 × 9.96 ÷ 100 = 16.93 g. Fiber = 170 × 2.00 ÷ 100 = 3.40 g. Net carbs = 16.93 − 3.40 = 13.53 g.
Carbohydrate Values by Beet Preparation
The table below summarizes the per-100g values used in the calculator. These are rounded for readability; the calculator uses the full reference values.
| Preparation | Total carbs | Sugars | Fiber | Net carbs |
|---|---|---|---|---|
| Raw / fresh | 9.6 g | 6.8 g | 2.8 g | 6.8 g |
| Boiled / drained | 10.0 g | 8.0 g | 2.0 g | 8.0 g |
| Pickled / canned | 17.5 g | 13.7 g | 1.6 g | 15.9 g |
Portion-Weight Tips
One medium beet (about 5–6 cm in diameter) weighs roughly 136 g raw. If you don't have a scale, using a measuring cup is convenient, but cup weights vary with how finely the beets are chopped or shredded. For the most accurate carb count, weigh cooked or raw beets on a kitchen scale in grams. Remember that boiled beets lose water, so a cooked cup contains more beet matter by weight than a raw cup. If your recipe calls for a specific number of medium beets, you can estimate 1 medium beet ≈ 0.3 lb ≈ 136 g, but actual weights can vary between 100 and 180 g.
For calorie-focused planning, you can also use the daily nutrition target calculator to place beet carbs in context alongside protein and fat targets.
Frequently Asked Questions
Are beets high in carbohydrates? Compared with leafy greens, beets are moderately high: raw beets contain about 9.6 g total carbs per 100 g. That is similar to carrots and sweet potatoes but less than white rice or bread. A 150 g serving provides about 14 g carbs, most of which comes from naturally occurring sugars.
What is net carbs in beets? Net carbs = total carbs − fiber. For raw beets, net carbs are about 6.8 g per 100 g because 2.8 g of the 9.6 g of carbs is fiber. If you use the net-carb option, the calculator subtracts fiber from total carbs automatically.
Why do pickled beets have so many more carbs? Pickled beets are often packed in a sweetened vinegar brine. The pickling liquid adds sugar, and some of that sugar is absorbed into the beet. If you are limiting carbs, drain and rinse pickled beets well, or choose no-sugar-added varieties.
Do beet greens count in this calculator? No. Beet greens are a separate leafy green with a much lower carbohydrate content. Use this calculator only for the beet root.
