How to convert 68 °F to Celsius
°C = (°F − 32) × 5/9
(68 − 32) × 5/9 = 36 × 5/9 = 180/9 = 20 °C
(68 − 32) × 5/9 = 36 × 5/9 = 180/9 = 20 °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 36 divides evenly by 9, so the answer is a whole number.
Estimate it in your head
Subtract 30 and halve: (68 − 30) ÷ 2 = 19 °C. That is 1 degree low, close enough to decide what to wear.
68 °F indoors and out
- Winter thermostat. 68 °F (20 °C) is the daytime winter setting the US Department of Energy suggests, lowering it while you sleep or are away.
- Room temperature. Recipes and labels that say “room temperature” usually mean about 68–72 °F (20–22 °C), which includes 68 °F.
- Outdoors. 68 °F is close to ideal for walking, cycling or eating outside.
