Price Per Gram Formula
How to Calculate Price Per Gram
- Find the total price - The amount you're paying for the product
- Convert quantity to grams - If the weight is in ounces, pounds, or kilograms, convert to grams
- Divide - Total price divided by quantity in grams
Worked Example
You're comparing two packages of gold tea bags:
- Package A: $29.99 for 100g
- Package B: $14.99 for 50g
Let's calculate:
Package A:
- Already in grams: 100g
- 0.30/g**
Package B:
- Already in grams: 50g
- 0.30/g**
Both packages have the same price per gram, so neither is better value.
Another Example - Different Values
You're comparing two brands of saffron:
- Brand A: $99.99 for 5g
- Brand B: $149.99 for 10g
Brand A:
- 19.998/g**
