Advanced Features

The Temperature Converter includes several advanced features for power users and specialized applications.

Historical Temperature Scales

Delisle Scale (°De)

• Origin: Created by French astronomer Joseph-Nicolas Delisle
• Characteristics: Higher values represent colder temperatures
• Range: 0°De (boiling water) to 150°De (freezing water)
• Use Case: Historical temperature records, especially in Russia

Newton Scale (°N)

• Origin: Created by Isaac Newton in 1701
• Characteristics: Based on the freezing and boiling points of water
• Range: 0°N (freezing water) to 33°N (boiling water)
• Use Case: Historical scientific literature

Réaumur Scale (°Ré)

• Origin: Created by René Antoine Ferchault de Réaumur
• Characteristics: Water freezes at 0°Ré and boils at 80°Ré
• Range: 0°Ré to 80°Ré for water's liquid range
• Use Case: Historical European measurements, some industrial applications

Rømer Scale (°Rø)

• Origin: Created by Danish astronomer Ole Christensen Rømer
• Characteristics: Water freezes at 7.5°Rø and boils at 60°Rø
• Range: 7.5°Rø to 60°Rø for water's liquid range
• Use Case: Historical Danish measurements

Precision and Accuracy

High Precision Support

• Decimal Places: Supports up to 15 decimal places for scientific accuracy

Conversion Formulas

Primary Conversions (via Celsius)

All conversions are calculated through precise mathematical relationships:

Kelvin: K = °C + 273.15
Fahrenheit: °F = °C × 9/5 + 32
Rankine: °R = K × 9/5
Delisle: °De = (100 - °C) × 3/2
Newton: °N = °C × 33/100
Réaumur: °Ré = °C × 4/5
Rømer: °Rø = °C × 21/40 + 7.5

Direct Conversions

For maximum accuracy, some conversions are calculated directly:

Fahrenheit to Rankine: °R = °F + 459.67
Kelvin to Rankine: °R = K × 9/5

Special Temperature Points

Absolute Zero

• Definition: The lowest possible temperature
• Value: 0 K = -273.15°C = -459.67°F
• Significance: All molecular motion stops

Triple Point of Water

• Definition: The temperature and pressure where water exists in all three phases
• Value: 273.16 K = 0.01°C = 32.018°F
• Significance: Used to define the Kelvin scale

Critical Point of Water

• Definition: The highest temperature and pressure where water can exist as a liquid
• Value: 647.096 K = 373.946°C = 705.103°F
• Significance: Beyond this point, water becomes a supercritical fluid

Practical Applications
