Price per Weight Calculator

Divide the total cost of the item by its total weight. For example, if a product costs $15 and weighs 500 grams, the price per gram is $15 ÷ 500 = $0.03 per gram. The formula is: Price per weight unit = Total cost ÷ Total weight.

To get the price per gram, divide the total price by the weight in grams. If you have the weight in another unit, convert it to grams first (e.g., 1 kg = 1000 g, 1 oz ≈ 28.3495 g). Then apply: Price per gram = Total price ÷ Weight in grams.

Divide $250 by 3 grams: $250 ÷ 3 ≈ $83.33 per gram. Enter 250 as the total price and 3 as the weight (in grams) in the calculator to confirm.

Divide the total cost by the total weight in pounds. For instance, a 60 lb item priced at $40 costs $40 ÷ 60 ≈ $0.67 per pound. Select 'Pounds (lb)' as the weight unit in this calculator and it will do the math for you.

$40 ÷ 60 lbs ≈ $0.6667 per pound. You can verify this by entering 40 as the total price, 60 as the weight, and selecting Pounds as the weight unit.

Retailers often sell the same product in different pack sizes at different prices. Comparing the price per gram or price per ounce lets you identify which size or brand offers better value, even when the quantities differ significantly.

If you're buying multiple identical items — say, 4 packs each weighing 500g — enter 4 in the Number of Items field. The calculator multiplies the single-item weight by that quantity before dividing, giving you an accurate price per weight unit across the entire purchase.

Yes. Enter the purchase price and the weight in your preferred unit (grams, ounces, kilograms, etc.). The calculator returns the cost per unit weight, which is the standard way to quote and compare precious metal prices.
