Temperature Conversion

Turkey uses degrees Celsius (°C) for temperature measurements.

Celsius to Fahrenheit

To convert Celsius to Fahrenheit:

Multiply by 1.8 and add 32

Example:

25°C × 1.8 + 32 = 77°F

Fahrenheit to Celsius

To convert Fahrenheit to Celsius:

Subtract 32, then multiply by 5/9

Example:

77°F − 32 × 5/9 = 25°C

Common Temperature References in Turkey

Celsius	Fahrenheit
0°C	32°F
10°C	50°F
20°C	68°F
25°C	77°F
30°C	86°F
35°C	95°F
