Question

The formula to convert Celsius to Fahrenheit is F-2C+32,

2C+32. Convert 87°F to Celsius.
O A. 55°C
B. 16°C
O C. 99°C
O D. 31°C"

Answer 1

To convert 87°F to Celsius, subtract 32 from the Fahrenheit temperature and then divide by 1.8. The result is approximately 30.56°C, which rounds to 31°C.

Step-by-step explanation:

To convert a temperature from Fahrenheit to Celsius, you can use the formula: C = (F - 32) / 1.8. To convert 87°F to Celsius, follow these steps:

1. Subtract 32 from the Fahrenheit temperature: 87 - 32 = 55.
2. Divide the result by 1.8 to find the Celsius temperature: 55 / 1.8 ≈ 30.56.

Therefore, 87°F is approximately 30.56°C, which when rounded to the nearest whole number, is 31°C.

The Celsius scale is sometimes called “centigrade” because it is based on a 100-degree interval between the freezing point and boiling point of water. The Fahrenheit scale, however, is based on a division of 180 degrees between the freezing and boiling points of water. The degree Celsius (°C) is 1.8 times larger than the degree Fahrenheit (°F) because the ratio of their intervals is 100/180 = 5/9.
