Raw to Cooked Calculator – Convert Food Accurately

Raw to Cooked Calculator – The Ultimate Tracking Guide

Anyone serious about building muscle, losing weight, or simply maintaining their weight can hardly avoid counting calories and macronutrients. But when meal-prepping or cooking daily, almost everyone stumbles over the same crucial problem: Do I weigh my food raw or cooked?

The short answer is: Always weigh raw! But in everyday life, this is not always possible (e.g., in the cafeteria or when cooking large portions). This is where the Raw to Cooked Calculator comes into play, solving the problem with mathematical precision.

Why does weight change when cooking?

The reason for the often drastic weight change during cooking is simply water. Depending on the type of food and the preparation method, one of two things happens:

1. Water Absorption (Factor > 1.0)

The classic example of foods that bind water when cooking are carbohydrate sources. Dry grain products and legumes soak up water when boiled.

• Convert raw to cooked rice: 100g of raw rice (approx. 350 kcal) turns into about 250g to 300g of cooked rice in the pot through water absorption.
• Pasta: Similar to rice, pasta absorbs an extreme amount of water. 100g of raw pasta easily weighs 250g after 10 minutes in boiling water.
• Oats & Lentils: Porridge or lentil stew also often triple their volume and weight.

The Result: The finished product is significantly heavier. But since water has no calories, the calorie density per 100g drops massively. 100g of cooked rice has significantly fewer calories than 100g of raw rice!

2. Water Loss (Factor < 1.0)

The exact opposite happens with protein-rich animal foods or highly water-containing vegetables.

• Raw to cooked chicken calories: A 200g raw chicken breast has about 220 kcal. Water evaporates when frying in the pan. After frying, the meat might only weigh 140g. However, these 140g still contain 220 kcal!
• Ground beef: When frying ground beef, not only water but also fat escapes. Therefore, the weight decreases drastically here too.
• Vegetables (e.g., Mushrooms): Anyone who has thrown 500g of mushrooms into a pan knows: After 10 minutes of frying, only a fraction of the volume is left.

Avoiding Common Calorie Tracking Mistakes

The most common and dangerous mistake on a diet (e.g., with apps like YAZIO or MyFitnessPal) is confusing raw and cooked nutritional values.

❌ Scenario 1: The Pasta Calorie Trap

You eat 300g of cooked pasta. But in your tracker app, you falsely select "Pasta (raw)" and enter 300g. The app now calculates over 1,050 kcal. In reality, 300g ofcooked pasta only have about 400 kcal (equivalent to approx. 110g of raw pasta). You think, you have reached your calorie goal, but are actually in a massive calorie deficit and wonder about cravings!

❌ Scenario 2: The Chicken Deception

You prepare a 250g turkey schnitzel (raw). On the plate lies a 170g heavy, fried schnitzel. You enter 170g "Turkey (raw)" in your app. The app calculates only approx. 185 kcal. Actually, you have eaten the calories of 250g of raw meat (approx. 275 kcal). So you unconsciously eat more calories through your conversion error and wonder why you're not losing weight!

Practical Examples for Perfect Meal-Prep

Our raw-to-cooked converter was specially developed for meal-prep enthusiasts. Let's see how you prep perfectly for the week on Sunday:

The 3-Day Curry Chicken

You want to prep chicken with rice for three days. You throw 600g of raw chicken(approx. 660 kcal / 138g protein) into the pan and cook 300g of raw rice (approx. 1,050 kcal).

After cooking, you weigh the total amounts in the kitchen:

• The cooked chicken weighs a total of 420g.
• The cooked rice weighs a total of 750g.

No need to despair! Take 3 Tupperware containers and distribute the meals:

• Each container gets 140g of cooked chicken (420g / 3).
• Each container gets 250g of cooked rice (750g / 3).

In your tracking app, simply enter exactly one third of the raw amounts for each day: I.e., 200g of chicken (raw) and 100g of rice (raw). The calculation adds up perfectly, the daily tracking is exact, and you save yourself hours of math!

The Solution: Use the FitScale Converter

If you eat in the cafeteria or can no longer weigh leftovers from the previous evening raw, our converter helps you. Select the food, specify whether the weight is raw or cooked, and type in the grams. The algorithm not only calculates the counterpart but also immediately gives you the correct macronutrients for your tracking app!
