Final answer:
To convert 85°F to Celsius, subtract 32 and then divide by 1.8, which results in 29.4°C. The term 'centigrade' for the Celsius scale refers to its 100-degree range between the freezing and boiling points of water.
Step-by-step explanation:
You deduct 32 from the Fahrenheit temperature and divide the result by 1.8 to convert 85°F to Celsius. That means you would compute (85 - 32) / 1.8. This gives you the temperature in Celsius, which is 29.4°C.
Because the Celsius scale is divided into 100 degrees, ranging from the freezing point (0°C) to the boiling point (100°C) of water at sea level, it is sometimes referred to as "centigrade." Consequently, the average daytime temperature is roughly 29.4°C.
