Complete Temperature Conversion Guide
This guide explains all major temperature conversions including Celsius (°C), Fahrenheit (°F), and Kelvin (K). You’ll find formulas, examples, comparison tables, and real-world applications—ideal for students, scientists, weather studies, cooking, medical usage and engineering.
Celsius to Fahrenheit (°C → °F)
The most common global conversion used in weather reports, cooking and daily temperature checks.
Formula
°F = (°C × 9/5) + 32
Example
25°C → (25 × 9/5) + 32 = 77°F
| °C | °F |
|---|---|
| 0 | 32 |
| 20 | 68 |
| 30 | 86 |
Fahrenheit to Celsius (°F → °C)
Formula
°C = (°F − 32) × 5/9
Example
98.6°F → (98.6 − 32) × 5/9 = 37°C
Celsius to Kelvin (°C → K)
Kelvin is widely used in physics, chemistry and scientific research.
Formula
K = °C + 273.15
Example
25°C + 273.15 = 298.15 K
Kelvin to Celsius (K → °C)
Formula
°C = K − 273.15
Example
310 K − 273.15 = 36.85°C
Fahrenheit to Kelvin (°F → K)
Formula
K = (°F − 32) × 5/9 + 273.15
Example
77°F → (77 − 32) × 5/9 + 273.15 = 298.15 K
Kelvin to Fahrenheit (K → °F)
Formula
°F = (K − 273.15) × 9/5 + 32
Example
300 K → (300 − 273.15) × 9/5 + 32 = 80.33°F
Quick Temperature Comparison Table
| °C | °F | K |
|---|---|---|
| 0 | 32 | 273.15 |
| 25 | 77 | 298.15 |
| 100 | 212 | 373.15 |

Frequently Asked Questions
1. Why do we use Celsius, Fahrenheit and Kelvin?
Different fields use different systems: Celsius for daily life, Fahrenheit in the US, and Kelvin in science.
2. What is absolute zero?
0 K is the lowest possible temperature where molecular movement stops.
3. Why does Fahrenheit scale feel larger?
Because 1°F is a smaller step than 1°C, so the scale appears stretched.
4. Is Kelvin ever negative?
No, Kelvin cannot go below zero.
5. Which is the scientific standard?
Kelvin (K) is globally accepted in scientific research.
Conclusion
Temperature conversions are essential for science, weather, cooking, engineering and daily life. With this guide and the Temperature Converter Tool, you can instantly switch between °C, °F and Kelvin accurately and easily.
