How to compare prices per kg
Price per kg puts food, raw materials and goods sold by weight on the same comparison basis.
Practical examples
$150.00 for 25 kg = $6.00/kg. Use the same calculation for rice, pet food, fertilizer, flour and raw materials.
When it helps
Use it for food, agricultural products, supplies and construction materials sold by weight.
Comparing per kg is useful when packages have different weights. A larger package is only cheaper when its cost per kilogram is lower too.
