Temperature Converter – Celsius, Fahrenheit & Kelvin Calculator
Temperature Conversion Formula
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

Common Temperature Conversion Problems and Answers
Frequently Asked Temperature Conversions
| Celsius (°C) | Fahrenheit (°F) | Kelvin (K) |
|---|---|---|
| 0 | 32 | 273.15 |
| 25 | 77 | 298.15 |
| 37 | 98.6 | 310.15 |

Step-by-Step Temperature Conversion Examples
Example 1: Convert 25°C to Fahrenheit
Using the temperature conversion formula: °F = (°C × 9/5) + 32
°F = (25 × 9/5) + 32 = (25 × 1.8) + 32 = 45 + 32 = 77°F
Example 2: Convert 68°F to Celsius
Using the formula: °C = (°F – 32) × 5/9
°C = (68 – 32) × 5/9 = 36 × 5/9 = 20°C
Understanding Temperature Scales
Celsius Scale
The Celsius scale, also known as centigrade, is based on the freezing point of water (0°C) and the boiling point of water (100°C) at standard atmospheric pressure. It’s the most commonly used temperature scale worldwide.
Fahrenheit Scale
The Fahrenheit scale sets the freezing point of water at 32°F and the boiling point at 212°F. It’s primarily used in the United States and a few other countries.
Kelvin Scale
Kelvin is the base unit of temperature in the International System of Units (SI). It starts at absolute zero (-273.15°C) and is commonly used in scientific calculations.
