F‑Score (F1) Calculator
Compute the F1 score—the harmonic mean of precision and recall—using: $$ F_1 = 2 \cdot \frac{\text{Precision} \times \text{Recall}}{\text{Precision} + \text{Recall}}. $$
* Enter precision and recall values (each between 0 and 1).

How It Works
The F1 score is defined as the harmonic mean of precision and recall:
$$ F_1 = 2 \cdot \frac{\text{Precision} \times \text{Recall}}{\text{Precision} + \text{Recall}}. $$
This measure balances precision and recall, providing a single metric for classification performance.
