27°C in Fahrenheit
The exact conversion, the formula, and a mental shortcut that is close enough for weather.
27 degrees Celsius is
80.6 °F
Rounded, that is about 81 °F. In Kelvin it is 300.15 K.
The formula
Multiply by 9/5 and add 32.
(27 × 9 ÷ 5) + 32 = 48.6 + 32 = 80.6 °F
For weather, a shortcut that needs no calculator is to double the Celsius and add 30: 27 × 2 + 30 = 84, against an exact 80.6. 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
Warm. Comfortable in light clothing, warm in direct sun.

Frequently asked questions
What is 27°C in Fahrenheit?
80.6°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.
