Enter the number of people, standard serving size per person, number of meals, and efficiency of food preparation into the calculator to determine the total food quantity needed.

## Food Quantity Formula

The following formula is used to calculate the quantity of food needed for a certain number of people.

FQ = (N * S * M) / E

Variables:

- FQ is the total food quantity needed (kg) N is the number of people S is the standard serving size per person (kg) M is the number of meals E is the efficiency of food preparation (%)

To calculate the total food quantity needed, multiply the number of people by the standard serving size per person, then multiply the result by the number of meals. Divide the result by the efficiency of food preparation.

## What is a Food Quantity?

Food quantity refers to the amount or volume of food that is consumed or required. It can be measured in various ways such as by weight, volume, number of items, or calories. The quantity of food needed can depend on various factors such as age, gender, physical activity level, and health status. Understanding food quantity is important for maintaining a balanced diet and for managing food supply and demand in food service operations.

## How to Calculate Food Quantity?

The following steps outline how to calculate the Food Quantity (FQ) using the given formula:

- First, determine the number of people (N).
- Next, determine the standard serving size per person (S) in kilograms.
- Next, determine the number of meals (M).
- Next, determine the efficiency of food preparation (E) as a percentage.
- Finally, calculate the Food Quantity (FQ) using the formula FQ = (N * S * M) / E.
- After inserting the variables and calculating the result, check your answer with a calculator.

**Example Problem:**

Use the following variables as an example problem to test your knowledge:

Number of people (N) = 10

Standard serving size per person (S) = 0.5 kg

Number of meals (M) = 3

Efficiency of food preparation (E) = 80%
