+/**
+ * Custom tempo/BPM measure for convert-units
+ *
+ * Converts between BPM and note durations in milliseconds
+ * Uses a reciprocal relationship where BPM (beats per minute) is the base unit
+ *
+ * Formula: milliseconds per beat = 60000 / BPM
+ *
+ * The to_anchor value represents the conversion factor:
+ * - For BPM → time units: multiply by to_anchor to get milliseconds
+ * - For time units → BPM: divide by to_anchor to get BPM
