Unit Price Calculator: formula & methodology
Cost per comparison unit = package price ÷ package quantity × number of units compared.
The tool uses your entered values and explicitly labeled assumptions. Final results may be rounded for display, while intermediate arithmetic retains available numeric precision. Verify material, tax, device or platform specifications relevant to your situation.
Worked example
A $10 package containing 100 g costs $10 per 100 g; a $15 package of 100 g costs $15 per 100 g.
Try the example above and then change values to reflect your own project or comparison.
Frequently asked questions
Must both quantities use the same unit?
Yes. Enter two measurements using the same displayed unit before comparing.
Should both pack sizes share one measurement unit?
Yes. Convert both to the same grams, milliliters, ounces or piece count before comparing prices.
