Should all the inputs flows and the output flow of the main product in a process be measured in USD ? Could I use other measurement units in order to do the Social LCA in Soca? For example, when I have data for the weight of an input flow, can i use kilograms? Does it work differently from PSILCA? Because in most of the examples I have seen, the input flow of a process and the basic products are in USD. Can i use different measurement units for the same functional unit?
Moreover, in order to calculate the working hours for a new process, where can I find data for the unit labour cost? Can I find it in Soca database?
Thank you in advance!
