    A 'parsec' means 'a distance corresponding to a parallax of one arc second'

    So where you got that a parsec is measured in degrees I'm not sure

    1 arcsecond = 1/3600th of a degree or 0.000277777o(degrees)

    that means replacing the arcsecond with the degree measurement gives: 1/ 0.000277777o = 3600o <----- I don't understand that part

    Have a look at this, namely the section 'Calculating the value of a parsec' - does that help?

    Right, so the relationship between arcseconds and the degree values do not correspond when talking about parsecs. Am I right?

    Can you post the question you're trying to solve?

    Is one parsec = 3600o according to the first post calculations?

    no, a parsec is not a measure of angles. it's not any amount of degrees. A parsec is a measure of distance based on using trig on the parallax angle observed from earth during it's orbit.
