Documentation page explaining how units are used #769
Description
I'm currently advising users to include units for commodities and currency, and have suggested that all other units can be determined from these. However, some more explanation would be helpful.
Give an example (e.g. a commodity with PJ units and currency USD), and then show what the units of all the other parameters should be
- commodity inputs/outputs
- commodity prices
- capital costs etc
- etc.
