>
> 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 been replaced by _Practical Salinity Unit_ (PSU), with values written without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.
