Here's how to convert 55 degrees Fahrenheit to Celsius:

Formula:

°C = (°F - 32) × 5/9

Calculation:

1. Subtract 32 from the Fahrenheit temperature: 55 - 32 = 23

2. Multiply the result by 5/9: 23 × 5/9 = 12.78 (approximately)

Therefore, 55 degrees Fahrenheit is approximately 12.78 degrees Celsius.
