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
