Calories Food Calculator Formula
The calculator uses two different formulas depending on the selected unit.
Formula for Foods Measured in Grams
Total Calories = (Calories Per 100g × Weight in Grams) ÷ 100Example
Rice contains:
130 kcal per 100gIf you eat:
200g riceCalculation:
Total Calories = (130 × 200) ÷ 100
Total Calories = 260 kcalFormula for Eggs
Since eggs are counted individually rather than weighed, the calculator uses:
Total Calories = Calories Per Egg × Number of EggsExample
One egg contains:
77 kcalFor 3 eggs:
Total Calories = 77 × 3
Total Calories = 231 kcalPractical Calculation Examples
Example 1: Apple
Food:
AppleAmount:
150gCalculation:
(52 × 150) ÷ 100
= 78 kcalResult:
78 Calories
Example 2: Banana
Food:
BananaAmount:
200gCalculation:
(89 × 200) ÷ 100
= 178 kcalResult:
178 Calories
Example 3: Chicken Breast
Food:
Chicken BreastAmount:
250gCalculation:
(165 × 250) ÷ 100
= 412.5 kcalResult:
412.5 Calories
Example 4: Peanut Butter
Food:
Peanut ButterAmount:
40gCalculation:
(546 × 40) ÷ 100
= 218.4 kcalResult:
218.4 Calories
Example 5: Eggs
Amount:
4 eggsCalculation:
77 × 4
= 308 kcalResult:
308 Calories
