Celsius to Fahrenheit (°C to °F)
Formula: °F = °C × 9/5 + 32
How to convert degrees Celsius to degrees Fahrenheit
°F = °C × 9/5 + 32
Example: 25 × 9/5 + 32 = 77, so 25 °C = 77 °F.
Celsius to Fahrenheit is used for weather forecasts, oven temperatures and body temperature when dealing with US sources.
A quick estimate is to double the Celsius value and add 30: 20 °C ≈ 70 °F (exactly 68 °F). At −40 the two scales meet: −40 °C equals −40 °F.

What is a degree Celsius?
On the Celsius scale water freezes at 0 °C and boils at 100 °C at sea-level pressure. It is used for weather, cooking and medicine in nearly every country except the United States.
What is a degree Fahrenheit?
On the Fahrenheit scale water freezes at 32 °F and boils at 212 °F, so there are 180 degrees between the two points instead of 100. It remains the everyday scale in the United States.
