Temperature Conversion Reference
Common Temperature Scales
- Celsius (°C): Most widely used temperature scale worldwide. Water freezes at 0°C and boils at 100°C at standard pressure. Used in science and most countries.
- Fahrenheit (°F): Used primarily in the United States. Water freezes at 32°F and boils at 212°F. Formula: °F = (°C × 9/5) + 32
- Kelvin (K): SI base unit of temperature. Absolute scale starting at absolute zero. 0 K = -273.15°C. Used in science. Formula: K = °C + 273.15
- Rankine (°R): Absolute temperature scale based on Fahrenheit. 0°R = absolute zero = -459.67°F. Used in some engineering fields. Formula: °R = °F + 459.67
Historical Temperature Scales
- Réaumur (°Ré): Historical scale once used in Europe. Water freezes at 0°Ré and boils at 80°Ré. Formula: °Ré = °C × 4/5
- Delisle (°De): Inverted scale where higher values mean colder temperatures. Water freezes at 150°De and boils at 0°De. Formula: °De = (100 - °C) × 3/2
- Newton (°N): Created by Isaac Newton. Water freezes at 0°N and boils at 33°N. Formula: °N = °C × 33/100
- Rømer (°Rø): Danish scale. Water freezes at 7.5°Rø and boils at 60°Rø. Formula: °Rø = °C × 21/40 + 7.5
Quick Reference Conversions
- 0°C = 32°F = 273.15 K = 491.67°R = 0°Ré
- 100°C = 212°F = 373.15 K = 671.67°R = 80°Ré
- 37°C (body temp) = 98.6°F = 310.15 K
- -40°C = -40°F (same in both scales)
- Absolute Zero = 0 K = -273.15°C = -459.67°F = 0°R
Common Temperature Values
- Absolute zero: 0 K = -273.15°C = -459.67°F
- Water freezing point: 0°C = 32°F = 273.15 K
- Room temperature: ~20°C = 68°F = 293 K
- Human body temperature: 37°C = 98.6°F = 310 K
- Water boiling point: 100°C = 212°F = 373.15 K
- Baking temperature: 180°C = 350°F = 453 K
- Sun's surface: ~5500°C = 9932°F = 5773 K
- Lowest recorded on Earth: -89.2°C = -128.6°F
- Highest recorded on Earth: 56.7°C = 134°F
Conversion Formulas
- Celsius to Fahrenheit: °F = (°C × 9/5) + 32
- Fahrenheit to Celsius: °C = (°F - 32) × 5/9
- Celsius to Kelvin: K = °C + 273.15
- Kelvin to Celsius: °C = K - 273.15
- Fahrenheit to Kelvin: K = (°F + 459.67) × 5/9
- Kelvin to Fahrenheit: °F = (K × 9/5) - 459.67
