Usage Guide

Step-by-Step Operation

1. Launch the application
2. Select desired conversion category from dropdown
3. Choose source unit in "From" field
4. Select target unit in "To" field
5. Input numerical value for conversion
6. Click "Convert" or press Enter for result
7. Use "Swap" to reverse conversion direction
8. Use "Clear" to reset input fields

Example Conversions

• Length: 10 Kilometers = 6.21371 Miles
• Temperature: 100 Celsius = 212 Fahrenheit
• Digital Storage: 1 Gigabyte = 1,073,741,824 Bytes

Technical Architecture

Conversion Methodology

The application implements a base-unit conversion system:

1. Convert input value to standardized base unit
2. Apply conversion factor to target unit
3. Format output with appropriate precision

Error Handling

• Invalid numerical input detection
• Overflow protection
• User-friendly error messages
