This engineering utility provides a three-parameter ratio calculator directly in your browser. It calculates a primary design output, secondary root metric, and ratio percentage from user-supplied inputs.

### Tool Implementation and Calculation Mechanics The interface takes three numeric fields and computes the following metrics in client-side code:

- **Primary Dimension / Load ($V_1$):** Baseline numerical parameter (default value is 100). - **Operating Coefficient ($V_2$):** Scaling coefficient (default value is 20). - **Safety / Rate Factor ($V_3$):** Divisor factor, clamped to a minimum of 0.01 to prevent division by zero (default value is 5).

**Evaluation Formulas:** - **Calculated Result:** $ ext{Output} = \frac{V_1 \times V_2}{\max(0.01, V_3)}$ - **Secondary Metric:** $ ext{Metric} = \sqrt{\max(0, V_1 \times V_2)}$ - **Efficiency / Ratio:** $ ext{Ratio (\%)} = \min\left(100, \max\left(0, \frac{V_1}{V_1 + V_2} \times 100\right)\right)$

*Note:* This tool component provides the three-variable proportional model above. It does not compute logarithmic decibel conversions ($P_{\text{dBm}} = 10 \log_{10}(P_{\text{mW}})$) or peak-to-peak AC voltage conversions ($V_{\text{pp}} = 2\sqrt{2 P R}$).

### Worked Numeric Example Using the tool default settings: - Primary Dimension / Load ($V_1$): 100 - Operating Coefficient ($V_2$): 20 - Safety / Rate Factor ($V_3$): 5

**Step-by-Step Calculation:** 1. **Calculated Result:** $(100 \times 20) / 5 = 2,000 / 5 = 400.00$. 2. **Secondary Metric:** $\sqrt{100 \times 20} = \sqrt{2,000} \approx 44.72$. 3. **Efficiency / Ratio:** $(100 / (100 + 20)) \times 100 = (100 / 120) \times 100 \approx 83.33\%$.

### Client-Side Processing Note All calculations are evaluated locally inside your web browser using standard JavaScript math functions. No inputs, numeric values, or session logs are sent across a network.
