It is pretty difficult to find Miller Analogies Test old scoring converted to new scoring. This is something Pearson simply has not provided, so it takes a couple of sources to try estimate a conversion between the two scores.
MAT old score to new score
On the old MAT, you received a raw score and a percentile score. The raw score was the number of correct answers you had out of a total of 100 questions (Miller Analogies Test old scoring). Pearson stopped using this scoring system back in 2004. While there probably was some sort of conversion chart at that time, it has been over a decade since then, and Pearson does not seem to maintain any official score conversion chart.
The best resource I have been able to find for an MAT score conversion is from California State University Stanislaus. You can follow the link, but I have also written up the conversion in case the information is ever taken down. Coincidentally, this chart references a Harcourt Assesment manual from 2004. Harcourt is a subdivision of Pearson, and this is likely a conversion chart they released to colleges shortly after switching from the old score to the new one.

How Accurate is this?
I have checked this chart against other official sources from Pearson as well as the Triple Nine Society, a high IQ society that accepts the MAT.
Triple Nine accepts a score of 85 on the old MAT scoring (raw) and a 472 on the new scoring (scaled). If you look this up on the chart, a score of 85 is converted to a 477. I have done these “cross checks” a few times, and the conversion chart is normally within 2-8 points. Overall, I think it provides an acceptable estimate for most purposes.
