Whether you’re planning a party, a corporate event, or simply trying to manage your household meals efficiently, knowing how much food to prepare can be a challenge. Our Food Quantity Calculator simplifies this task by providing a straightforward way to determine the total food quantity required based on your inputs.

Formula: The total food quantity (FQ) is calculated using the following formula: FQ = (Number of People * Standard Serving Size * Number of Meals) / Efficiency

How to Use:

  1. Enter the number of people expected to be served.
  2. Input the standard serving size per person in kilograms.
  3. Specify the number of meals to be served.
  4. Enter the efficiency of food preparation as a percentage.
  5. Click the “Calculate” button to get the total food quantity needed.

Example: Let’s say you’re organizing a picnic for 50 people. Each person is expected to consume 0.3 kg of food, and you’re planning to serve 3 meals. Assuming an efficiency of 80%, the calculator will determine the total food quantity required.
