Celsius (°C)
Celsius is the most widely used unit of temperature. It is part of the metric system and is based on water’s freezing and boiling points.
Key Facts
- Freezing point of water: 0 °C
- Boiling point of water: 100 °C
- Formula to Fahrenheit: °F = (°C × 9/5) + 32
- Formula to Kelvin: K = °C + 273.15
Where It’s Used
- Weather forecasts in most countries.
- Cooking recipes in Europe and Asia.
- Medical thermometers worldwide.
Examples
- A healthy body temperature is 37 °C.
- Room temperature is about 22 °C.
- Ice melts at 0 °C.
Fahrenheit (°F)
Fahrenheit is commonly used in the United States. It was created by Daniel Gabriel Fahrenheit in 1724.
Key Facts
- Freezing point of water: 32 °F
- Boiling point of water: 212 °F
- Formula to Celsius: °C = (°F − 32) × 5/9
- Formula to Kelvin: K = (°F − 32) × 5/9 + 273.15
Where It’s Used
- Weather reports in the US.
- Oven settings and household thermostats.
- Everyday temperature references in American culture.
Examples
- A normal body temperature is 98.6 °F.
- Room temperature is around 70 °F.
- Hot summer weather often exceeds 100 °F.
Kelvin (K)
Kelvin is the SI unit of temperature, used mainly in science and engineering. Unlike Celsius or Fahrenheit, it does not use the degree symbol.
Key Facts
- Absolute zero: 0 K = −273.15 °C
- Freezing point of water: 273.15 K
- Boiling point of water: 373.15 K
- Formula to Celsius: °C = K − 273.15
- Formula to Fahrenheit: °F = (K − 273.15) × 9/5 + 32
Where It’s Used
- Physics and thermodynamics.
- Astronomy, measuring star temperatures.
- Engineering and scientific calculations.
Examples
- Room temperature: 293–298 K.
- Sun’s surface: 5778 K.
- Absolute zero: 0 K, the lowest possible temperature.
Temperature 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 − 32) × 5/9 + 273.15
- Kelvin to Fahrenheit: °F = (K − 273.15) × 9/5 + 32
These formulas ensure that every temperature conversion is precise and reliable.
