A list of links to different google doc spreadsheets which work out how much of each raw material you will need to produce requested quantities of end products.
The spreadsheets will improve in time, in order to become more efficient, and may start to include other helpful figures, such as cost and quality.

*This guide assumes you have researched all industries from your base starting one.
** Each Production spreadsheet is independent of all others, which means that if you are producing products required by the other industries, it won't take this into account. You will have to work that out yourself... for now.
