13°C in Fahrenheit
The exact conversion, the formula, and a mental shortcut that is close enough for weather.
13 degrees Celsius is
55.4 °F
Rounded, that is about 55 °F. In Kelvin it is 286.15 K.
The formula
Multiply by 9/5 and add 32.
(13 × 9 ÷ 5) + 32 = 23.4 + 32 = 55.4 °F
For weather, a shortcut that needs no calculator is to double the Celsius and add 30: 13 × 2 + 30 = 56, against an exact 55.4. 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
Cool. Jacket weather rather than coat weather.

Frequently asked questions
What is 13°C in Fahrenheit?
55.4°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.
