Personality Type and the Big Five
Two personality frameworks can overlap at the group level without providing a valid conversion for an individual.

What each framework describes
Jungian type models and the Big Five organize personality in different ways. Similar labels do not make their scores interchangeable.
Jungian type preferences
OpenJung uses the OEJTS to describe preferences across four paired dimensions and summarizes them as a four-letter type.
Big Five traits
The Big Five measures five broad traits—openness, conscientiousness, extraversion, agreeableness, and neuroticism—on continuous scales.
What group correlations mean
Research can find that scores from two frameworks tend to vary together across a group. That describes an average association in the sample; it does not determine either score for a particular person.
Why there is no profile converter here
A four-letter type does not contain enough information to calculate five personal trait scores. Assigning fixed percentages would create unsupported precision and hide the variation among people who share a type.
OpenJung has not administered a Big Five questionnaire, so your OpenJung result does not include measured Big Five traits. A Big Five profile requires a suitable Big Five assessment.
Properly scoped research
McCrae and Costa (1989) compared MBTI preference scores with Five-Factor Model measures in a specific sample. The study helps explain overlap between constructs and questioned strict type dichotomies; it was an original study, not a meta-analysis, and it did not validate converting a type code into personal Big Five percentages.

Treat your OpenJung result as a description of Jungian preferences. If you also complete a Big Five assessment, compare the two results side by side rather than translating one into the other.
