How to convert 59 °F to Celsius
(59 − 32) × 5/9 = 27 × 5/9 = 135/9 = 15 °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. Here 27 divides evenly by 9, so the answer is a whole number.
Estimate it in your head
Subtract 30 and halve: (59 − 30) ÷ 2 = 14.5 °C. That is 0.5 degrees low, close enough to decide what to wear.
What 59 °F feels like
59 °F (15 °C) is roughly the average temperature of Earth’s surface taken over the whole year and the whole globe — mild for a single day, but a useful yardstick for climate.
Indoors, 59 °F is below the 68 °F daytime winter setting the US Department of Energy suggests for saving energy, so a home this cool would usually have the heat on.
