1. What is Price per 100g?

Price per 100g is a standardized unit price calculation that allows consumers to compare the cost of products regardless of their packaging size. It's particularly useful in the UK where products are often sold in varying quantities.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• Price — The product cost in British Pounds (GBP)
• Weight — The product weight in grams (g)

Explanation: This calculation normalizes prices to a 100g basis, making it easy to compare products sold in different quantities.

3. Importance of Price Comparison

Details: Calculating price per 100g helps consumers identify the best value products, especially when comparing different package sizes or brands. Many UK supermarkets display this information on shelf labels.

4. Using the Calculator

Tips: Enter the product price in GBP (e.g., 1.50) and the weight in grams (e.g., 250). The calculator will show the equivalent price for 100g of the product.

5. Frequently Asked Questions (FAQ)

Q1: Why calculate price per 100g instead of per kg?
A: 100g is a more intuitive unit for most food items in the UK, where package sizes are often in the hundreds of grams rather than kilograms.

Q2: Does this work for liquid products?
A: Yes, as long as you know the weight in grams. Note that 1ml of water = 1g, but other liquids may have different densities.

Q3: How accurate should my measurements be?
A: For best results, use exact weights from product packaging. Estimates will give approximate comparisons only.

Q4: Should I always choose the lowest price per 100g?
A: Not necessarily - consider quality, brand preference, and whether you'll use the full quantity before it expires.

Q5: Why do some products show price per kg and others per 100g?
A: UK retailers typically use price per kg for heavier items and price per 100g for smaller quantities, but our calculator standardizes everything to 100g.
