1. What is the Wh per Litre Calculation?

The Wh per litre calculation converts the caloric content of food (in kilocalories per litre) to an equivalent energy measurement in watt-hours per litre. This conversion is useful for comparing food energy with electrical energy systems.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( kcal\ per\ litre \) — Energy density of food in kilocalories per litre
• 1.162 — Conversion factor from kcal to Wh

Explanation: This conversion factor comes from the relationship between kilocalories and watt-hours (1 kcal = 1.162 Wh).

3. Importance of Energy Conversion

Details: Converting food energy to electrical energy units allows for interesting comparisons between biological and technological energy systems, and can be useful in food science and energy research.

4. Using the Calculator

Tips: Enter the energy density of the food in kilocalories per litre. The value must be positive.

5. Frequently Asked Questions (FAQ)

Q1: Why convert food calories to watt-hours?
A: This conversion allows comparison between biological energy (food) and electrical energy systems, useful in research and education.

Q2: How accurate is this conversion?
A: The conversion is mathematically exact based on the defined relationship between kilocalories and watt-hours.

Q3: What's a typical Wh/L value for common foods?
A: High-energy foods like oils might be around 800-900 Wh/L, while watery foods might be under 100 Wh/L.

Q4: Can this be used for any food?
A: Yes, as long as you know the energy density in kcal/L, the conversion applies to any food or beverage.

Q5: Is this useful for dietary planning?
A: Primarily this is for scientific comparisons, though it could help visualize food energy in electrical terms.
