PyraMathBench - Unit Conversion: leaderboard

A text-only subtask of PyraMathBench (2026), a hierarchical math benchmark derived from word problems: the unit conversion subtask (1,093 items). Items are scored 0-100 with partial credit for small numeric error, zero-shot chain of thought, median of three samples; higher is better.

Metric: Score (0-100) on the unit conversion subtask (1,093 items), score (0-100) per item: numeric answers score 100 within 1e-4 and fall linearly to 0 at 1 percent relative error, expressions are matched with Math-Verify, text answers by MathBERT cosine similarity of at least 0.9 and choices by exact match; zero-shot chain of thought, median of three samples at temperature 0.7; higher is better.
