Do you know how the conversion should be done? I honestly don't know how I should proceed to get the proper value and unit out of the conversion.

I did read all posts. First to convert lb/lbf to kg/N I would muliply my starting value 0,596 by 0,4535 (lb to kg) and divide it by 4,448 (lbf to N). What I need is end unit of kg/N*s so I would divide everything with 3600. I need a value of meters at the end of the range equation so now: -I...

"As a guy who has been working with these unit all my life, I can tell you that 1 lbm/hr is the same as 0.4536 kg/hr. The weight of this is (0.4546)(9.8)=4.448 N/hr. And we know that 1 lbf=4.448 N. So, to convert from imperial to metric in this case, all you need to do is divide by 3600" quote...

But the weight of 1 lb is 1 lbf right? So the ingoing is in fact 1/h and then converted into 1/s. Test: I get the same result, if I divide 0,596 / 3600

Ok, Thanks! I guess I found the right conversion: TSFC = (0.596lb)/(lbf⋅h) = ((0.596lb)/(lbf⋅h))⋅(4.448N/lbf)⋅((0.4536kg/lbm)^(−1))⋅((3600s/h)^(−1)) * (9,81m/s^2) = 0,0001655555555 1/s Can you confirm that this would be the right result of the conversion?

So the multiplication g*SFC is incorrect? And the equation should look like R = (cl/cd) * (V/(SFC)) * ln(w0/w1) ?

Homework Statement Hi to all, the Task I struggle with, is the range calculation from an Airbus A320 with the Breguet Range Equation which is defined as: Homework Equations R = (cl/cd) * (V/(g*SFC)) * ln(w0/w1) with V = velocity g = gravity SFC = specific fuel consumption w0 =...
