1 scfh = 0.4719474 ltr/min
1 scfh = 0.4719474 ltr/min

Nop!!

1 ft^3/h = 28.316847 ltr/h (exactly) = 0.4719474.. ltr/min
This expression is absolutely correct, but the following shall be noted:

the "standard state" in "English Unit" usually means 60℉ and 1 atmosphere, while the "normal state" in "Metric Unit" is based on 0℃ 1 atmosphere.

1 scfh = 1 std. ft^3/h = [0.4719474 * (460+32)R/(460+60)R] N ltr/h
= 26.79209.. N ltr/h = 0.446535 N ltr/min

So the word 'standard state' shall clearly be defined
