hello
How can we convert the ''heat value'' of natural gas from BTU/scf to kcal/Nm3 at atmospheric pressure and 60 F (15.6 C) temperature. I face problem in converting scf to Nm3 at a given temp and press.

Hello Abdulla,
According to this website;- http://www.qbmconsultants.com/conversion.html
1MJ/Nm3 = 25.368 BTU/scf = 238.8 kcal/Nm3
Therefore, 1 BTU/scf = 9.41 kcal/Nm3
(Standard cubic feet is measured at 60oF, 1 atm. while Normal cubic meter is at 0oC, 1atm.)
Regards,
Ted.

Thank you mr. Ted for your replay

Dear Ted;
According to above website:
1 MJ/Nm3 = 25.368 BTU/scf = 238.8 x 102 kcal/Nm3
1MJ/NM3 = 25.368 BTU/scf = 243.576 kcal/Nm3
Then;
BTU/scf = 9.60 kcal/Nm3 Not 9.41 kcal/ Nm3 . Am I right or I have missed something?
Best Regards
Nael
