## Description

A professional hardness conversion tool designed for mechanical engineering, metal heat treatment, and quality management, providing quick, stable, and traceable engineering reference data.

**Key Features**

1. **Industrial-Grade Precision**
   The conversion logic is based on ASTM E140 / ASTM A370 standards, utilizing high-density reference points and linear interpolation to deliver stable and reproducible conversion results.

2. **Flexible Input and Real-Time Synchronization**
   Allows direct input in any hardness field (e.g., HRC / HV / HBW), with real-time conversion across other units, enhancing on-site operational efficiency.

3. **Physical Range Protection Mechanism**
   Built-in effective range checks for each scale, displaying "No Reference Value" when out of range, reducing the risk of misinterpretation.

4. **Customizable Interface**
   Enables toggling unit displays and drag-and-drop sorting to create a workspace tailored to individual or production line processes.

5. **Image Conversion (Beta)**
   Supports photo/album import, area selection recognition, result comparison, and manual correction, suitable for quick conversion of reports and on-site records.

6. **Batch Conversion**
   Allows multiple data entries for rapid conversion, retaining the last used unit preference to minimize repetitive actions.

**Supported Units**

- Rockwell: HRC, HRA, HRB, HRD, HRF
- Superficial Rockwell: HR15N, HR30N, HR45N, HR15T, HR30T, HR45T
- Brinell: HB, HBW
- Vickers: HV
- Tensile Strength: MPa
