It is a convenient app that allows you to easily find the lowest price by calculating the price per gram of multiple products. You can easily calculate which one is cheaper when weight and price are different in shopping. You can find the lowest price by calculating the price per gram and the weight per yen for multiple products with different weight and price. You can change the notation of gram into the number of pieces, and change into units of length and volume such as meters and liters. You can easily change the notation of the weight per 1 gram or 100 gram, and conversely the weight per 1 yen, making it easy to see which is cheaper. If you enter two or more, the input fields will automatically increase, so you can compare as many as you want. Blanks are excluded from the comparison, so unnecessary columns will not be included in the comparison if you remove the weight or amount.
