💡 Temperature Conversion Formulas (based on Kelvin):
Celsius °C = K - 273.15
Fahrenheit °F = K × 9/5 - 459.67
Rankine °R = K × 9/5
Delisle °De = 3/2 × (373.15 - K)
Newton °N = (K - 273.15) × 33/100
Réaumur °Ré = (K - 273.15) × 4/5
Rømer °Rø = (K - 273.15) × 21/40 + 7.5
Unit Symbol Description Freezing Point (0°C)
Kelvin K SI base temperature scale 273.15 K
Celsius °C Most commonly used temperature unit 0 °C
Fahrenheit °F Used in US and other countries 32 °F
Rankine °R Imperial absolute temperature scale 491.67 °R
Delisle °De Historical unit, rarely used today 150 °De
Newton °N Historical unit 0 °N
Réaumur °Ré Historical unit 0 °Ré
Rømer °Rø Historical unit 7.5 °Rø
📝 Common Use Cases:
• Scientific research: Use Kelvin (K) or Celsius (°C)
• Daily life: Celsius (°C) or Fahrenheit (°F)
• Engineering calculations: Kelvin (K) or Rankine (°R)
• Historical documents: Delisle, Newton, etc.
🔍 Temperature Reference Points:
• Absolute zero: 0 K = -273.15 °C = -459.67 °F
• Water freezing point: 273.15 K = 0 °C = 32 °F
• Water boiling point: 373.15 K = 100 °C = 212 °F
