Units
EDCS adopts the ISO International System of Units (SI)
- Ref: http://physics.nist.gov/cuu/Units/index.html
- Defines:
- Seven SI base units
- SI derived units
- SI supplemental units (radian and steradian)
- SI scaled units based on standard prefixes
- SI associated units outside the SI, but are important and widely used
- Also temporary units, which are outside the SI but currently accepted for use with the SI by NIST. Their continued use is not encouraged.
Currently completing migration to full SI compliance in this area (complete with EDCS Version 3.0)
- Will allow only units of the correct “type” to apply to each EAC
- E.g., measures of length vs. mass
