How to Use This Tool
Enter the name of your food item, the quantity you plan to eat, and select the appropriate unit (grams, ounces, cups, or pieces). Then, input the protein, carbs, and fat content per 100 grams for that food. Click "Calculate" to see a detailed breakdown of macros for your portion. Use "Reset" to clear all fields and start over.
Formula and Logic
The tool calculates macros based on the quantity entered and the nutritional values per 100 grams. It converts units to grams for consistency (e.g., 1 ounce = 28.35 grams). The total macros are derived by scaling the per-100g values by the quantity factor. Calories are estimated using the standard 4-4-9 rule (4 calories per gram of protein or carbs, 9 per gram of fat).
Practical Notes
- Serving Adjustments: For mixed dishes, estimate the proportion of each ingredient and calculate separately.
- Time-Saving Tips: Save common food profiles (e.g., chicken breast, rice) in a notes app for quick reference.
- Cost Considerations: Higher protein foods like lean meats may cost more; balance with affordable carbs like beans.
- Common Unit Conversions: 1 cup ≈ 240 ml for liquids; for solids, use a kitchen scale for accuracy.

Frequently Asked Questions
What if I don't know the macros per 100g?
You can find this information on nutrition labels, food databases, or apps like MyFitnessPal. For whole foods, reliable sources include the USDA FoodData Central.
Can I use this for cooked vs. raw food?
Yes, but note that cooking can change weight and nutrient density. Use values specific to the state you're measuring (e.g., raw chicken vs. cooked).
How accurate are the calorie estimates?
Calories are approximate and based on standard values. For precise tracking, consider consulting a dietitian or using lab-tested data.
Additional Guidance
