How to convert 74 °F to Celsius
°C = (°F − 32) × 5/9
(74 − 32) × 5/9 = 42 × 5/9 = 210/9 = 23.33 °C
(74 − 32) × 5/9 = 42 × 5/9 = 210/9 = 23.33 °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. 42 is not a multiple of 9, so the exact answer is the repeating decimal 23 1/3 °C.
Estimate it in your head
Subtract 30 and halve: (74 − 30) ÷ 2 = 22 °C. That is 1.3 degrees low, close enough to decide what to wear.
74 °F indoors and out
- Thermostats. The US Department of Energy suggests 68 °F in winter and 78 °F in summer when you are home; 74 °F is between the two.
- Room temperature. Recipes and labels that say “room temperature” usually mean about 68–72 °F (20–22 °C).
- Outdoors. 74 °F is close to ideal for walking, cycling or eating outside.
