Wrap calories per gram is a simple but powerful number: it tells you how energy-dense your tortilla or wrap is, so you can compare brands, adjust portions, and plan meals around your calorie goals. This calculator takes the total calories and weight listed on the package — or from your kitchen scale — and converts it into calories per gram, per 100 grams, and per ounce.
It's especially useful for people tracking calories or macros, meal-prepping lunches, or swapping between different wrap types such as flour, whole wheat, spinach, and low-carb versions. Just enter the package values or click a preset to get an instant breakdown, including a step-by-step look at the math. Whether you're counting every calorie or simply curious about how wraps compare to other breads, this free tool gives you a reliable reference in seconds.

How to Use This Tool
Start by finding the nutrition facts on your wrap package — most brands list both calories per serving and the serving size in grams. Enter those two numbers into the calculator. If you weighed your wrap on a kitchen scale instead of using the label, enter the scale weight and the corresponding calories (check the label's calories-per-gram by dividing, or use the brand's full package info).
- Choose the weight unit: grams or ounces.
- Optionally enter a serving size in grams to see how many calories a custom portion contains.
- Press Calculate to get calories per gram, per 100 g, per ounce, and per serving.
- Use the presets for quick reference, then adjust if your wrap differs from the typical values.
How Calorie Density Is Calculated
The math is straightforward: calories per gram = total calories ÷ total weight in grams. That single number is the wrap's energy density. To express it on the standard food label basis, multiply by 100 to get calories per 100 grams. To get calories per ounce, multiply by 28.35, since one ounce equals 28.35 grams.
Because wraps can vary widely in thickness, flour type, and added fat, the same 'wrap' label can have very different per-gram values. The per-100 g number is especially useful when comparing brands: it removes serving-size differences and lets you compare calorie density directly. This is the same concept used in the broader USDA FoodData Central database, where nutrition values are usually reported per 100 g.
Worked Examples
Example 1 — Flour tortilla. A standard 8″ flour tortilla weighs 74 g and contains 210 kcal. Calories per gram = 210 ÷ 74 = 2.84 kcal/g. Per 100 g = 284 kcal. A typical 56 g serving therefore contains 2.84 × 56 = 159 kcal.
Example 2 — Whole wheat wrap. A 56 g whole wheat wrap has 180 kcal. Energy density = 180 ÷ 56 = 3.21 kcal/g. That's 321 kcal per 100 g and roughly 91 kcal per ounce.
Example 3 — Low-carb wrap. A 45 g low-carb wrap contains 90 kcal. Calorie density = 90 ÷ 45 = 2.00 kcal/g. Per 100 g = 200 kcal. Despite being called 'low-carb', it may still have a similar calorie density to a larger flour tortilla if you eat a bigger serving.
Typical Wrap Calorie Values
Values below are common averages from popular brands and food databases. Your exact product may differ — use the label whenever possible.
| Wrap type | Typical weight | Calories | kcal/g | kcal/100 g |
|---|---|---|---|---|
| Flour tortilla, 8″ | 74 g | 210 | 2.84 | 284 |
| Whole wheat wrap | 56 g | 180 | 3.21 | 321 |
| Spinach wrap | 50 g | 160 | 3.20 | 320 |
| Low-carb wrap | 45 g | 90 | 2.00 | 200 |
| Yellow corn tortilla, 6″ | 28 g | 62 | 2.21 | 221 |
| Sundried tomato wrap | 60 g | 190 | 3.17 | 317 |
Tips for Accurate Tracking
- Weigh wraps in grams rather than relying on 'one tortilla' counts. Brand sizes vary a lot.
- If the label only gives per-100 g values, divide by 100 to get per gram, then multiply by your wrap's weight.
- For wraps used in meal prep, weigh the whole package and divide by the number of wraps to find the true average weight.
- Remember that calorie per gram changes if moisture is lost — for example, a toasted wrap weighs less but has the same calories, so its per-gram number goes up.
- When building a burrito bowl or sandwich, count the wrap separately from the fillings. This tool only handles the wrap itself.
Frequently Asked Questions
What is a good calories-per-gram number for a wrap?
There's no single 'good' number — it depends on your goals. A typical flour tortilla is about 2.8–3.2 kcal/g. Low-carb and thin wraps often drop to around 2.0–2.5 kcal/g, while indulgent wraps with added butter or oil can reach 3.5–4.0 kcal/g.
Can I use this for other flatbreads?
Yes. Enter any flatbread's calories and weight, including pita, naan, lavash, or tortillas. The calculation works for any food where you know total calories and total grams.
Is calories per gram the same as calories per 100 g?
No. Calories per gram is the raw density (for example, 2.84 kcal/g). Per 100 g is simply that value multiplied by 100. Both describe the same energy density, just on different scales.
Why does my wrap's label look different from the table?
Manufacturers use different recipes, flour blends, and serving sizes. Also, some labels round calories to the nearest 5 or 10 kcal, so the exact per-gram value can vary. Use this calculator with the label on your specific product for the most accurate result.
