How to Convert Celsius to Fahrenheit
To convert Celsius to Fahrenheit, multiply the Celsius temperature by 1.8 (or 9/5), then add 32. For example, to convert 25°C: (25 × 1.8) + 32 = 45 + 32 = 77°F. A quick shortcut: double the Celsius value and add 30 for a rough estimate.
Worked Example: Convert 0 °C to °F
Start with the value in celsius
0 °C
Apply the formula
°F = (0 × 9/5) + 32
Calculate the result
0 °C = 32 °F
