Formula:`Energy = grams × density × 4.184`

## Introduction to Grams to Calories Conversion

This formula calculates the energy in calories from the given mass in grams and the density of the substance. The energy is calculated by multiplying the mass (in grams) by the density and the conversion factor 4.184, which accounts for the conversion from Joules to calories. The result provides the energy content in nutritional calories which is commonly used for food labeling and measurements.

## Parameter usage:

• `grams`= mass in grams
• `density`= density of the substance

## Example valid values:

• `grams`= 100
• `density`= 2

## Output:

• `energy`= energy in calories

## Data validation

The mass in grams and density should be greater than zero.

## Summary

This converter can be used to determine the energy in calories from the given mass and density of a substance. It is commonly used in nutritional and food science applications.
