Understanding Temperature Scales
Temperature Scales
Celsius (°C): Most commonly used worldwide, water freezes at 0°C and boils at 100°C
Fahrenheit (°F): Primarily used in the United States, water freezes at 32°F and boils at 212°F
Kelvin (K): Scientific scale where 0K is absolute zero, water freezes at 273.15K
Rankine (°R): Absolute temperature scale used in engineering, 0°R = absolute zero
Key Reference Points
• Absolute Zero: -273.15°C, -459.67°F, 0K, 0°R
• Water Freezing: 0°C, 32°F, 273.15K, 491.67°R
• Water Boiling: 100°C, 212°F, 373.15K, 671.67°R
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
Fahrenheit to Rankine: °R = °F + 459.67
Practical Applications
Temperature conversion is essential for cooking, weather forecasting, scientific research, engineering, and international communication.
Quick Tips
• Use quick presets for common temperatures
• Remember that -40°C = -40°F (the crossover point)
• Kelvin is always positive (no negative values)
• For cooking, Celsius and Fahrenheit are most common
