---------------------------------------
Summary: Units.PSU should have a scale value of 1/1000
Key: SIS-413
URL: https://issues.apache.org/jira/browse/SIS-413
Project: Spatial Information Systems
Issue Type: New Feature
Components: Utilities
Affects Versions: 0.8
Reporter: Martin Desruisseaux
Assignee: Martin Desruisseaux
Fix For: 1.0
Sea Water Salinity was used to be measured in g/kg, with values sometime
written with the "‰" symbol (e.g. "35‰"). In modern oceanography, this has been
replaced by _Practical Salinity Unit_ (PSU), with values written without symbol
(e.g. "35"). Strictly speaking, PSU units are not convertible to g/kg. However
the PSU scale is by design very close to the old scale. If someone nevertheless
attempts a conversion between those two scales, we want it to be close to the
identity operation. Currently, the conversion wrongly multiply or divide values
by 1000.
