Hi,
I try to found how represent the Einstein unit with udunits, I have
found this old message (1999) on your mailing list :
>> Does udUnits support microEinsteins (a unit typically used for
>> measuring Photosynthetically Active Radiation (PAR))? If not, will it?
> The UDUNITS package doesn't currently support the einstein unit. It
> could, however. What is the definition of an einstein?
Is Einstein unit still not implemented?
Some web links to the definition of this unit:
