1. What is Price per 100g?

The price per 100g is a standardized way to compare product prices regardless of package size. It's particularly useful in Australia where many products are sold in different quantities, making direct price comparisons difficult.

2. How Does the Calculator Work?

The calculator uses this simple formula:

Where:

• \( Price \) — Product price in Australian Dollars (AUD)
• \( Weight \) — Product weight in grams

Explanation: This calculation normalizes the price to a standard 100g quantity, allowing easy comparison between different sized products.

3. Importance of Price Comparison

Details: Calculating price per 100g helps Australian consumers make informed purchasing decisions and identify the best value products, especially when comparing different package sizes or brands.

4. Using the Calculator

Tips: Enter the product price in AUD and its weight in grams. Both values must be positive numbers. The calculator will show you the standardized price per 100g.

5. Frequently Asked Questions (FAQ)

Q1: Why use price per 100g instead of total price?
A: Different package sizes make direct price comparisons misleading. Price per 100g standardizes the comparison.

Q2: Is this calculator specific to Australia?
A: While the formula works anywhere, this calculator uses AUD currency which is most relevant for Australian shoppers.

Q3: Can I use this for liquids sold by volume?
A: For water-based liquids (density ~1g/mL), you can approximate grams = milliliters. For other liquids, this may not be accurate.

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

Q5: Does this work for bulk purchases?
A: Yes, it's particularly useful for comparing bulk vs regular sizes to determine if bulk is truly better value.
