Quantity, Symbol, Unit, Unit Symbol
I’ve put together, with Mrs Mac’s help, a document with quantity, symbol, unit and unit symbol so that you know the meaning of the terms in the Relationships Sheet. It is in EXCEL so that you can sort it by course, quantity or symbol.
Quantity, Symbol, Units the excel sheet
Quantity, Symbol, Units a pdf sheet sorted by course and then alphabetical by quantity.
This is the same information in readily available Tablepress form. If you click on the Higher tab at the top it should sort by terms that you need in alphabetical order, or search for a term. Let me know if I’ve missed any.
