Convert Natural Gas lbs/sec to Mcf

I am faced with bringing in data that reads in lbs/sec and I need to convert that to Mcf. The product is Natural Gas. It is for a power plant.
If anyone has any suggestions, I am at a complete loss as to how to convert it.

Thanks in advance

What you'll need to do is convert pounds of natural gas to cubic feet. Checking a few MSDS' for natural gas gave me a specific gravity of 0.5 to 0.7 g/cc. I'm using the average of 0.6 g/cc, you may need to change this for your final calculation.

Code:

     g         lb           cc          lb
0.6 -- x 2.205 -- x 28316.8 --- = 37.37 ---
    cc          g           ft³         ft³


What you'll need to do is divide your flow rate in lbs/sec by 37.37 to get a flow rate in Ft³/sec. Multiply this by 360 if your trying to get to Cubic Feet per Hour, which is a more standard unit.
