Use this free chia calories per 100g calculator to find out exactly how many calories are in your chia seed portion — whether you measure it in grams, ounces, tablespoons, or teaspoons. Dried chia seeds are one of the most calorie-dense superfoods around: a 100-gram serving delivers about 486 kcal along with 16.5 g protein, 30.7 g fat, 42.1 g total carbs, and 34.4 g fiber. That's why a small spoonful can add a surprising number of calories to smoothies, puddings, or overnight oats.
This tool is designed for meal planners, calorie counters, low-carb dieters, and home cooks who want reliable nutrition numbers without digging through food databases. Enter your portion, choose the unit, and hit Calculate to see calories plus a full macro breakdown, including net carbs. You'll even get a step-by-step calculation and a copyable summary for your food log. For quick entries, use the preset tablespoons or grams buttons to instantly fill a common portion size.

Calculation Method
The calculator uses the widely cited nutrition profile for dried chia seeds: approximately 486 kcal per 100 g, with 16.5 g protein, 30.7 g fat, 42.1 g total carbohydrate, and 34.4 g fiber. Your portion is converted to grams using these equivalences: 1 oz = 28.3495 g, 1 tablespoon = 12 g, and 1 teaspoon = 4 g. Each nutrient is then scaled as (serving grams ÷ 100) × per-100 g value. Net carbs are total carbohydrates minus fiber.
Worked Example
Example: 2 tablespoons of chia seeds.
2 tbsp × 12 g/tbsp = 24 g. Calories: 24 ÷ 100 × 486 = 116.6 kcal. Protein: 24 ÷ 100 × 16.5 = 4.0 g. Fat: 7.4 g. Total carbs: 10.1 g. Fiber: 8.3 g. Net carbs: 10.1 − 8.3 = 1.8 g.
Reference Values per 100 g
| Nutrient | Amount per 100 g |
|---|---|
| Calories | 486 kcal |
| Protein | 16.5 g |
| Total Fat | 30.7 g |
| Total Carbohydrate | 42.1 g |
| Dietary Fiber | 34.4 g |
| Net Carbs | 7.7 g |
Low-Carb and Keto Context
Because chia seeds are roughly 82% fiber by carbohydrate weight, net carbs are surprisingly modest. The 7.7 g net carbs per 100 g is lower than many grains and flours, making chia a popular thickener and egg substitute in low-carb baking. Still, the fat content is high, so portions add up quickly from a calorie standpoint.
Common Mistakes to Avoid
- Confusing dry and soaked weights. Always measure dry seeds unless a recipe states otherwise.
- Using a generic 'tablespoon' that assumes 10 g per tbsp instead of 12 g — small differences compound over a week.
- Forgetting that added liquids or sweeteners in chia pudding contribute extra calories.
Frequently Asked Questions
Are chia calories the same after soaking? The dry weight doesn't change, but the volume increases dramatically. Soaking doesn't change calories, though you are eating more water weight.
Why do different labels show slightly different values? Chia is a natural product; values vary by harvest and brand. The USDA FoodData Central entry lists 486 kcal per 100 g, which is the basis for this tool.
