If the cost of coffee is $20 per kilogram, what is the cost per gram?

To determine the cost per gram of coffee when it costs $20 per kilogram, it is essential to understand the relationship between kilograms and grams. One kilogram is equivalent to 1,000 grams. Therefore, to find the cost per gram, you divide the total cost per kilogram by the number of grams in a kilogram.

Calculating this:

Cost per gram = Total cost per kilogram / Number of grams in a kilogram

Cost per gram = $20 / 1,000 grams

Cost per gram = $0.02

This demonstrates that the cost of coffee is $0.02 per gram, making this the correct answer. Understanding this conversion is crucial for accurate pricing and cost analysis in situations involving bulk coffee purchases.
