Calculating the price per 100 grams of a product can help consumers compare the cost-effectiveness of different products regardless of their packaging size. This practice is commonly used in grocery stores and supermarkets to help shoppers make informed decisions.
Historical Background
The concept of unit pricing, such as price per 100 grams, has been around for decades, helping consumers to better understand the value of products they purchase. It standardizes the way prices are compared, making it easier to identify the most economical options.
Calculation Formula
The formula to calculate the price per 100 grams is given by:
\[ \text{PP100G} = \frac{\text{TP}}{\text{W}} \times 100 \]
where:
- \(\text{PP100G}\) is the Price Per 100G (\$/100g),
- \(\text{TP}\) is the total price (\$),
- \(\text{W}\) is the weight in grams (g).
Example Calculation
If you buy a bag of coffee for $15 weighing 500 grams, the price per 100 grams is calculated as:
\[ \text{PP100G} = \frac{15}{500} \times 100 = 3 \]
This means the coffee costs $3 per 100 grams.
Importance and Usage Scenarios
This calculation is particularly useful in grocery shopping, allowing consumers to compare prices of products sold in varying quantities. It provides a clear metric to gauge which product offers more value for money, especially when discounts or different brands make direct comparison challenging.
