How To Calculate Calories Without Scale

Calories: 0

Calculating calories is an essential part of managing your diet and maintaining a healthy lifestyle. While food scales are commonly used to measure portions for accurate calorie counting, it’s not always practical to have one on hand. In this article, we’ll provide a convenient calculator to help you estimate the calorie content of your food without the need for a scale.

Formula: To calculate calories without a scale, we use the following formula: Calories = (Portion Size / 100) * Calories per 100g

How to Use:

  1. Enter the name of the food in the “Food Name” field.
  2. Input the portion size in grams in the “Portion Size” field.
  3. Provide the calories per 100g of the food in the “Calories per 100g” field.
  4. Click the “Calculate” button to get the estimated calorie count.

Example: Suppose you have 150 grams of chicken breast with 165 calories per 100g. Enter the information into the calculator, and it will estimate the calories for your portion.


  1. Q: Can I use this calculator for any food? A: Yes, you can use this calculator for any food item as long as you know the portion size and the calories per 100g.
  2. Q: What if I have an 8-ounce portion? A: You’ll need to convert the portion size to grams. There are approximately 28.35 grams in an ounce.
  3. Q: How accurate is this method? A: It provides a reasonably accurate estimate, but for precise measurements, a food scale is recommended.
  4. Q: Are there apps that can do this too? A: Yes, many diet and nutrition apps have built-in calculators for estimating calories without a scale.
  5. Q: Can I calculate calories for cooked food as well? A: Yes, as long as you know the calories per 100g for the cooked food.

Conclusion: Calculating calories without a scale is a handy skill for anyone conscious of their dietary intake. This calculator provides a quick and easy way to estimate the calorie content of your food portions. While it may not be as precise as using a scale, it can help you make informed choices about your diet and nutrition. Remember that for the most accurate results, a food scale is your best option.
