How do I find total recipe calories?

Add up the calories from each ingredient using nutrition labels or a food database. Online tools like USDA FoodData Central provide calorie data for most foods.

Are calories the same as kilocalories?

In nutrition, "calories" on labels means kilocalories (kcal). 1 food calorie = 1 kcal = 1000 scientific calories.

How accurate are calorie calculations?

Home calculations are estimates, typically within 10-20% of actual values. Cooking methods, ingredient brands, and portion sizes all introduce variability.
