How to convert degrees Celsius to degrees Fahrenheit
°F = °C × 9/5 + 32
Example: 25 °C → 77 °F
Temperature scales have different zero points, so you cannot convert them with a single multiplication factor.

About these units
Celsius (°C): Celsius (°C) sets 0° at the freezing point and about 100° at the boiling point of water at sea level. It is used for weather in almost every country.
Fahrenheit (°F): Fahrenheit (°F) puts water’s freezing point at 32° and boiling point at 212°. It is used for everyday temperatures in the United States.
