Yes, that is correct according to my calculations.
As far as "S 38 degrees 15 minutes E", that looks correct, too - if fact I thought I posted that, but guess I edited it out. It's the same as S38°15'E anyway, using words instead of symbols. But "S 38 degrees E 15 minutes" I don't think is in correct format. Glad I'm not the only one.
I converted to decimal (141.75°) mainly because FizzyCalc requires it.
