Hello @philippeVerney,

Could you please let me know how to get the Quantity of a resqml unit from fesapi (java) ?

For example:  
[http://docs.energistics.org/#ECOM2/ECOM2\_TOPICS/ECOM2-000-207-0-R-sv2000.html](http://docs.energistics.org/#ECOM2/ECOM2_TOPICS/ECOM2-000-207-0-R-sv2000.html)

The unit ‘m’ is measuring the quantity ‘LengthUom’  
The unit ‘gAPI’ measuring the quantity ‘APIGammaRayUom’

Thanks,  
Shakir

Hi @shakirhusain,

It is unfortunately not supported at all yet (C+, .NET, Java, neither Python).  
It is always on the todo list with the big topic named “Support for Energistics Unit Of Measure” which is necessary for RESQML but also WITSML, PRODML and OSDU. But no time, no funding for it so far.

Regards  
Philippe
