Need to build a tool to calculate area or weight
I need a tool to create for my business purpose (which should be easy and simple involves no coding). Use case of the tool is at first I need to select from a list of options say Iron plate, Iron sheet etc then I should be able to enter the dimensions of the item lets say length, width and thickness of the particular item (I should have the option to select the unit of dimension like mm, mtr, inches) and the final output is the weight of the particular item entered.
Please suggest the best possible and easy way to do this.
