Formula used
Price per ounce (weight):
total_oz = quantity × convert_to_oz(size_per_unit, unit)
price_per_oz = total_price / total_ozPrice per fluid ounce (volume):
total_floz = quantity × convert_to_fl_oz(size_per_unit, unit)
price_per_fl_oz = total_price / total_flozConversions:
- 1 lb = 16 oz
- 1 oz = 28.349523125 g
- 1 kg = 35.27396195 oz
- 1 US fl oz = 29.5735295625 mL
- 1 L = 33.8140227 US fl oz

FAQs
What does price per ounce mean?
It is the total price divided by the total ounces. For volume items this is price per fluid ounce. Lower values usually indicate better value for money.
What is the difference between ounce and fluid ounce?
Ounce (oz) measures weight or mass. Fluid ounce (fl oz) measures volume. This calculator converts weight units to oz and volume units to US fl oz automatically.
Can I compare multipacks?
Yes. Set quantity to the number of units in the pack. The calculator multiplies the converted ounces by that quantity before dividing the price.
Which currencies are supported?
Any currency symbol you type. The symbol is applied to totals and price per ounce output for clarity. Calculations are unit based and currency agnostic.
How precise are the conversions?
We use standard constants (e.g., 1 oz = 28.349523125 g and 1 US fl oz = 29.5735295625 mL). Outputs are rounded for readability but computed with full precision.
Can I export and share results?
Use the CSV or PDF buttons. CSV opens in spreadsheets. PDF is formatted like the on‑screen table and includes your chosen currency symbol.
Does this work for metric sizes?
Absolutely. Enter grams, kilograms, milliliters, or liters and the calculator converts to ounces or fluid ounces before computing the price per ounce.
