Example 1: - You have a container with 700g of coffee and it costs €4.95. What is the price per kilo? - Type the shop and coffee make, then input "700" in the area "write grams here", type "4" in the area "$", write "95" in the area "¢", Calculate and the price per kilo appears.

Example 2: - You want to purchase a bag containing 11.5 kilograms of coal for $15, and want to calculate how much it works out per kilogram. Input the retailer and coal type, then move your mouse to the arrow "g" and select "kg" in the drop-down menu. Type "11" in the field "write kilograms here", type "5" in the decimals field next to it marked "000", type "15" in the area "$", leave the area "¢" empty, Calculate and the computed price per kilo is displayed.

Example 3: - You live in Ireland and want to buy some candy online from the USA. The candy costs $59.99 in a case containing 24 boxes of 2.125oz. How much is it per kilo? First, you must use a calculator to obtain the total weight: 24 x 2.125oz = 51oz. Now, you know that the total weight of the candies is 51oz. On, enter the shop and candy name, move your mouse to the "g" arrow, and select the "US" dropdown item. Leave the "pounds" fields empty, write "51" in the "ounces" field, type 59 in the "$" field, type "99" in the "¢" field. The site automatically converts ounces into kilograms. Calculate and the cost per kg is there to see! Of course, if you are comparing with the price of the local store, do not forget to include shipping into the cost of the item.
