The Spring Carbs Calculator helps you quickly estimate the carbohydrate content of fresh spring produce — from asparagus and green peas to radishes, strawberries, rhubarb, and tender leafy greens. Add one food or combine up to four items from a single meal or snack, then see the total carbs, net carbs, fiber, and sugar at a glance.
Enter amounts in grams, ounces, or cups, and the calculator converts everything using typical serving weights. A built-in net-carb option subtracts fiber for people following keto or low-carb diets, while the per-food breakdown keeps things transparent for anyone tracking macros, managing blood sugar, or simply trying to eat more seasonal vegetables.
Whether you’re meal-prepping spring lunches or just curious about the carbs in a bowl of strawberries, this tool gives you a fast, practical estimate based on standard nutrition data.
🌱 Spring Produce Carb Counter
Add up to 4 fresh spring foods, pick a unit, and get total carbs, net carbs, fiber, and sugar in seconds.

How to Use This Tool
Enter an amount next to each food you want to include. Choose the unit — grams, ounces, or cups — that matches how you measured it, then press Calculate Carbs. The calculator converts every serving to grams and multiplies by the food's carb, fiber, and sugar values per 100g.
Leave any row blank and it will simply be skipped, so you can estimate a single snack or a four-item salad bowl. Use the Net Carbs toggle if you follow a low-carb or keto plan — this subtracts fiber from total carbs. The preset buttons quickly fill row 1 with common portion sizes.
How It Works
All values are based on USDA FoodData Central entries for raw, fresh produce. The calculation for each food is simple:
Carbs = (serving in grams ÷ 100) × carbs per 100g
Fiber and sugar are calculated the same way with their own per-100g values. For ounce entries the tool multiplies by 28.35 to get grams; for cups it uses the typical weight of one measuring cup of that food (see the reference table below). Totals are summed across all rows.
Worked Example
Breakfast berries: 1 cup of strawberries (166g) and 100g of rhubarb.
Strawberries: 166g × 7.7g/100g = 12.8g carbs, 3.3g fiber, 8.1g sugar.
Rhubarb: 100g × 4.5g/100g = 4.5g carbs, 1.8g fiber, 1.1g sugar.
Totals: 17.3g carbs, 5.1g fiber, 9.2g sugar — about 12.2g net carbs.
Reference Data: Spring Foods at a Glance
Per 100g of raw produce, from USDA FoodData Central:

| Asparagus | 3.9g | 2.1g | 1.3g | 134g |
| Green peas | 14.5g | 5.7g | 5.7g | 145g |
| Radishes | 3.4g | 1.6g | 1.9g | 116g |
| Spinach | 3.6g | 2.2g | 0.4g | 30g |
| Artichoke | 10.5g | 5.4g | 1.0g | 170g |
| Strawberries | 7.7g | 2.0g | 4.9g | 166g |
| Rhubarb | 4.5g | 1.8g | 1.1g | 122g |
| Spring onions | 7.3g | 2.6g | 2.3g | 89g |
| Fennel bulb | 7.3g | 3.1g | 3.9g | 87g |
| Swiss chard | 3.7g | 1.6g | 1.1g | 36g |
| Arugula | 3.7g | 1.6g | 2.1g | 20g |
Tips for Accurate Tracking
- Weigh produce raw, before cooking. Cooking removes water and concentrates carbs by weight, so per-100g values for cooked vegetables can be higher.
- For salads, remember that a whole small plate of leafy greens weighs far less than it looks — a couple of cups of arugula is only about 40g.
- Peas and artichoke are the higher-carb entries here; if you are watching portions, measure them instead of eyeballing.
- Net carbs (total carbs minus fiber) are most relevant to ketogenic and very low-carb plans. For general blood-sugar tracking, total carbs plus the fiber and sugar breakdown give more context.
Limitations & Data Notes
Frequently Asked Questions
Why does the calculator show a per-food breakdown? Because totals hide useful patterns. A bowl with 200g of peas and a bowl with 200g of spinach have very different carb loads; the breakdown shows where the carbs come from so you can adjust portions.
Should I count net carbs? For most people, total carbohydrate is the value used on nutrition labels and in standard meal planning. Net carbs matter mainly for keto and some low-carb protocols, and this tool gives you both.
Are frozen spring vegetables the same? Not exactly. Frozen peas and spinach are usually harvested at peak ripeness and nutritionally similar, but values still differ slightly from raw fresh produce. Cooked values differ as well because water content changes.
Where can I look up other spring foods? The USDA FoodData Central search is the authoritative public source for food composition data. You can also use the general net carb calculator for foods outside this list.
