Price Per Litre Formula:
| From: | To: |
Price per litre is a unit price measurement that calculates the cost of a liquid product per litre. It's commonly used to compare prices of beverages, fuels, cleaning products, and other liquids sold in different volumes.
The calculator uses a simple formula:
Where:
Explanation: This calculation helps standardize the cost of liquids regardless of packaging size, making it easier to compare prices between different products and quantities.
Details: Calculating price per litre is essential for smart shopping and budgeting. It allows consumers to make accurate comparisons between different package sizes and brands to find the best value for money.
Tips: Enter the total cost in dollars and the volume in litres. Both values must be positive numbers. The calculator will instantly compute the price per litre.
Q1: Why calculate price per litre instead of just comparing package prices?
A: Package prices can be misleading. Larger packages often seem like better value but may actually cost more per unit. Price per litre allows for accurate comparison.
Q2: Can I use this calculator for other units like milliliters or gallons?
A: Yes, but you'll need to convert to litres first (1000mL = 1L, 1 gallon ≈ 3.785L).
Q3: Does this work for products sold by weight instead of volume?
A: For weight-to-volume comparisons, you'll need to know the density of the product. This calculator is specifically for liquids sold by volume.
Q4: Should I always buy the product with the lowest price per litre?
A: Not necessarily. Consider your actual needs, storage space, and whether you'll use the product before it expires.
Q5: How accurate do my measurements need to be?
A: For general comparison, approximate values are fine. For precise budgeting, use exact values from your receipts and product labels.
