1. Open the converter in a modern web browser
2. Ensure JavaScript is enabled
3. Allow page to load completely (chart may take 2-3 seconds to initialize)

2. Basic Conversion

To Convert Temperatures:

1. Enter Temperature in any one field:
   • Celsius (°C)
   • Fahrenheit (°F)
   • Kelvin (K)
2. Click the “Convert” button (purple button below input fields)
3. View Results in other temperature units:
   • Converted values appear automatically in all fields
   • Results rounded to 2 decimal places
   • Values update in real-time

Example:
To convert 100°C to other units:

1. Type “100” in Celsius field
2. Click Convert
3. See:
   • Fahrenheit: 212°F
   • Kelvin: 373.15K

3. Graph Visualization

The interactive chart shows:

• Temperature scale relationships (-50°C to 100°C range)
• Three parallel scales:
  • Blue line: Celsius
  • Green line: Fahrenheit
  • Red line: Kelvin

To Use the Graph:

1. Hover over lines to see exact values
2. Click legend items to toggle visibility
3. Drag to pan (on desktop)
4. Use mouse wheel to zoom

4. Error Handling

If you see a red error message:

1. Check input fields:
   • Only one field should contain value
   • Ensure numeric values only (no letters/symbols)
2. Clear all fields
3. Re-enter value in one field
4. Click Convert again

5. Mobile Usage

• Automatically adapts to screen size
• Portrait mode:
  • Inputs stack vertically
  • Chart remains interactive
• Landscape mode:
  • Standard desktop layout
• Touch gestures supported:

  • Drag to pan

6. Advanced Features

Real-Time Conversion (Pro Tip):

1. Type value in any field
2. Press Enter (instead of clicking Convert)
3. Instant results without button click

Temperature Comparison:

1. Convert multiple values
2. Compare results in different units
3. Observe proportional differences in graph

7. Troubleshooting

If converter stops working:

1. Refresh page (F5/Ctrl+R)
2. Clear browser cache

8. Frequently Asked Questions

Q: How accurate are the conversions?
A: 100% precise using scientific formulas approved by NIST.

Q: Why decimal places vary?
A: Automatic precision based on:

• 2 decimals for °C and °F
• 2 decimals for Kelvin (except whole numbers)

Q: Can I interact with the graph?
A: Yes! Use:

• Hover for values
• Click legend to toggle lines
• Zoom/pan controls

Q: Does it work offline?
A: After initial load, yes! Conversions work offline.

Q: What conversion formulas are used?
A:

• °F = (°C × 9/5) + 32
• K = °C + 273.15
• °C = (°F – 32) × 5/9
