Common Temperature Conversion Formulas
| Conversion | Formula | Example |
|---|---|---|
| Celsius to Fahrenheit | °F = (°C × 9/5) + 32 | 20°C = 68°F |
| Fahrenheit to Celsius | °C = (°F - 32) × 5/9 | 68°F = 20°C |
| Celsius to Kelvin | K = °C + 273.15 | 25°C = 298.15K |
| Kelvin to Celsius | °C = K - 273.15 | 300K = 26.85°C |
| Fahrenheit to Kelvin | K = (°F - 32) × 5/9 + 273.15 | 98.6°F = 310.15K |

Temperature Scales Explained
Celsius Scale (°C)
Developed by Swedish astronomer Anders Celsius in 1742. The Celsius scale is based on the freezing and boiling points of water at sea level, with 0°C as the freezing point and 100°C as the boiling point. It's used by most countries worldwide and is the standard for scientific work (except in some specific fields).
- Used in most of the world (except USA)
- Metric system temperature scale
- Simple water-based reference points
- Easy to use for everyday purposes
Fahrenheit Scale (°F)
Developed by German physicist Daniel Gabriel Fahrenheit in 1724. The Fahrenheit scale originally used the freezing point of brine as 0°F and human body temperature as 96°F. Today, it's defined with water freezing at 32°F and boiling at 212°F. It's primarily used in the United States and a few other countries.
- Primarily used in the United States
- Imperial system temperature scale
- Smaller degree increments than Celsius
- Common in weather reports in some countries
Kelvin Scale (K)
Developed by British physicist William Thomson (Lord Kelvin) in 1848. The Kelvin scale is an absolute temperature scale that starts at absolute zero (the theoretical point where all molecular motion stops). It uses the same degree increment as Celsius but starts at -273.15°C. It's the standard unit of temperature in the International System of Units (SI).
- Absolute temperature scale
- Starts at absolute zero (0K = -273.15°C)
- Used in scientific research
- SI unit for temperature
💡 Temperature Conversion Tips
- Quick °C to °F: Double Celsius, subtract 10%, add 32 (approximate)
- Quick °F to °C: Subtract 32, divide by 2, add 10% (approximate)
- Celsius to Kelvin: Simply add 273.15
- Easy reference: 28°C ≈ 82°F (pleasant weather)
