5°C in Fahrenheit
The exact conversion, the formula, and a mental shortcut that is close enough for weather.
5 degrees Celsius is
41 °F
Rounded, that is about 41 °F. In Kelvin it is 278.15 K.
The formula
Multiply by 9/5 and add 32.
(5 × 9 ÷ 5) + 32 = 9 + 32 = 41 °F
For weather, a shortcut that needs no calculator is to double the Celsius and add 30: 5 × 2 + 30 = 40, against an exact 41. It drifts by about 2 °F per 10 °C, which is fine for deciding what to wear and useless for cooking.
What this temperature feels like
Cold. A proper coat, and most people will want gloves at the lower end.

Frequently asked questions
What is 5°C in Fahrenheit?
41°F. Multiply the Celsius figure by 9/5 and add 32.
What is the formula?
°F = (°C × 9/5) + 32. To go the other way, °C = (°F − 32) × 5/9.
At what temperature are the two scales equal?
−40. That is the single point where Celsius and Fahrenheit give the same number, which makes it a handy check on any conversion you do by hand.
