I tend to use the Uconeer conversion software, cos I'm lazy, this free software converts from mass to volumetric flowrate for standard and non-standard gasses along with many other conversions.

This question has been raised several times on ENGTIPS

Take care with the use of 15°C (59°F) and 60°F (15.55556°C), both of which are used for 'Standard' conditions in metric or "British" units respectively and have tended to be used interchangably.
Also, the conversion can be affected by the water content.

As for many participants in these forums English is not my mother-tongue, Spanish is, and what we write is not precisely that which we think. One moment of distraction and see what happens ... I noticed the error (right instead of write) a millisecond after sending the message. Anyway, I hoped I'd conveyed my idea regarding normal and standard T,P. Thanks again.
