As requested, here is the list of customUnits used by sbclter (to date). The current version of this list can be found at the url above. Several of these units need addional attributes or definition. These are commonly-used units in oceanography and limnology.

<unit id="reciprocalMeter" name="reciprocalMeter" unitType="lengthReciprocal" abbreviation="m-1" parentSI="meter" multiplerToSI="1">

per meter, describes optical properties

<unit id="reciprocalMetersPerSteradian" name="reciprocalMetersPerSteradian" unitType="lengthReciprocal" abbreviation="m-1*sr-1" parentSI="meter" multiplerToSI="">

describes directional optical measurements

<unit id="microwattsPerSquareCentimeterPerNanometer" name="microwattsPerSquareCentimeterPerNanometer" unitType="power" parentSI="joule">

irradance unit

<unit id="microwattsPerSquareCentimeterPerNanometerPerSteradian" name="microwattsPerSquareCentimeterPerNanometerPerSteradian" unitType="power" parentSI="joule">

directional irradiance unit

<unit id="microeinsteinsPerSquareMeterPerSecond" name="microeinsteinsPerSquareMeterPerSecond" unitType="energy" parentSI="joule">

PAR irradiance unit, Seabird 911. 1Ein = energy of 1 mole photons

<unit id="microeinsteinsPerSquareCentimeterPerSecond" name="microeinsteinsPerSquareCentimeterPerSecond" unitType="energy" parentSI="joule">

PAR Scalar irradiance unit. 1Ein = energy of 1 mole photons

<unit id="decibar" name="decibar" unitType="pressure" abbreviation="dbar" parentSI="pascal" multiplerToSI="10,000">

pressure, oceanography

<unit id="hectoPascal" name="hectoPascal" unitType="pressure" abbreviation="hPa" parentSI="pascal" multiplerToSI="100">

SI unit for atmospheric pressure, equivalent in magnitude to millibar

<unit id="percent" name="percent" unitType="massPerMass" abbreviation="o/o" parentSI="gramsPerGram" multiplerToSI=".01">

parts per hundred

<unit id="permil" name="permil" unitType="massPerMass" abbreviation="o/oo" parentSI="gramsPerGram">

parts per thousand relative to a std composition. UC-delta used for isotope enrichment = (Rx / Rs - 1) ·1000. o/oo used for salinity

<unit id="sigma_unit" name="sigma_unit" unitType="massDensity" parentSI="killogramsPerCubicMeter" constantToSI="-1000" multiplerToSI="1">
