Quick estimate: −1.5 °C

How to convert 27 °F to Celsius

°C = (°F − 32) × 5/9
(27 − 32) × 5/9 = −5 × 5/9 = −25/9 = −2.78 °C

Subtract 32 first because the two scales put zero in different places, then multiply by 5/9 because a Fahrenheit degree is only 5/9 the size of a Celsius degree. −5 is not a multiple of 9, so the exact answer is the repeating decimal −2 7/9 °C.

Estimate it in your head

Subtract 30 and halve: (27 − 30) ÷ 2 = −1.5 °C. That is 1.3 degrees high, close enough to decide what to wear.

What 27 °F means in everyday life

Freezers. Home freezers should hold 0 °F (−17.8 °C), so 27 °F is 27 degrees warmer than a properly set freezer — still cold enough to keep ice solid.
Ice. At −2.78 °C, puddles, ponds and wet roads freeze. Rock salt melts ice well near 32 °F but works more and more slowly as pavement temperatures drop into the teens and below.
Wind chill. With wind, 27 °F feels much colder:

Wind	Feels like	In °C	Note
10 mph	18 °F	−8 °C	Dress in layers
20 mph	13 °F	−10 °C	Dress in layers
30 mph	11 °F	−12 °C	Dress in layers

Temperatures near 27 °F

22 °F	−5.56 °C	267.59 K
23 °F	−5 °C	268.15 K
24 °F	−4.44 °C	268.71 K
25 °F	−3.89 °C	269.26 K
26 °F	−3.33 °C	269.82 K
27 °F	−2.78 °C	270.37 K
28 °F	−2.22 °C	270.93 K
29 °F	−1.67 °C	271.48 K
30 °F	−1.11 °C	272.04 K
31 °F	−0.56 °C	272.59 K
32 °F	0 °C	273.15 K

Going the other way: −3 °C in Fahrenheit is 26.6 °F.

Frequently asked questions

What is 27 °F in Celsius?

27 °F is −2.78 °C: subtract 32 (−5) and multiply by 5/9.

Is 27 °F hot or cold?

27 °F is below freezing — water turns to ice and roads can be slick.

How do you convert 27 °F to Celsius in your head?

Subtract 30 and divide by 2: (27 − 30) ÷ 2 = −1.5 °C, compared with the exact −2.78 °C.

What is 27 °F in Kelvin?

27 °F is 270.37 K. Convert to Celsius (−2.78 °C) and add 273.15.
