Frequently Asked Questions
How do I calculate price per unit?
Divide the total price by the quantity. A 500g pack for £2.00 costs £0.004 per gram, or £4.00 per kilogram. Make sure both items use the same unit of measure for a valid comparison.
Why does the bigger pack sometimes cost more per unit?
While larger packs are usually better value, this is not always the case. Retailers occasionally price larger sizes at a higher per-unit rate, especially for premium or branded products. Always check before assuming bigger means cheaper.
