SG calculation is incorrect. SG is always lower than density at the same temperature
Appears to be accurate but not precise For NPL & LPG may not be precisely accurate past the 4th significant digit. I can't tell if it is the ASTM implementation examples that are wrong, or what, but I can't get my own implementation to converge using Table 23 without rounding. Looks like this app may be suffering the same problem. Accurate to at least 4 significant digits and easy to use. Cheers.
Good It works, even LPG. Thanks.
