Hi @joolek.o​,

Welcome to the FME Community!

To convert arcseconds to degrees you can use an ExpressionEvaluator transformer and use the expression in the screenshot below. Here the arcseconds value is held in an attribute named "ArcSeconds" and will create a new attribute named "Degrees" (just type that into the "New Attribute" parameter box)

wow! FME community is just... who r u guys I mean I've heard u r kind and helpful but experiencing it.. will give a go in the morning!! Thank you
