Intern:Conversion

Conversion of units: Parameter defining concentrations of substances (e.g. nutrients) in water are mostly defined with unit Mol per liter ! If data are provided in units different from those in Pangaea and can be converted, please find the related factors below. A parameter should never be defined twice with two different units (exception: units can not be converted).

mymol/kg to mymol/l --> multiply with factor 1.025 (! just a mean value > in principle dependent from substance and density of sea water !)

Oxygen
 * µmol/l >  µmol/kg * 1.025
 * µmol/l >  ml/l * 44.66
 * µmol/l >  mg/l * 31.25
 * µg-at/l > (mg/l * 1000)/16   |   mg/l  >  (µg-at/l * 16)/1000

Nitrogen
 * µg-at/l > (mg/l * 1000)/14.01

Phosphorus
 * µg-at/l > (mg/l * 1000)/30.97

Silicon
 * µmol/l >  µg/l * 0.03561

Barium
 * µmol/l >  µg/l * 0.007282
