How it is calculated
Unit price = price / quantity
Worked example
750 g at €2.19 costs €2.92/kg. A 1 kg pack at €2.79 costs €0.13 less per kilogram.
Things to check
- Convert both quantities to the same unit first, for example 750 g = 0.75 kg. Quality and delivery charges may affect the comparison.
- Use one currency consistently. Examples use euros; the calculation works with any currency.
