Here's how to convert Fahrenheit to Celsius:

Formula:

Celsius = (Fahrenheit - 32) * 5/9

Calculation:

1. Subtract 32 from the Fahrenheit temperature: 145 - 32 = 113

2. Multiply the result by 5/9: 113 * 5/9 = 62.78 (approximately)

Therefore, 145 degrees Fahrenheit is approximately 62.78 degrees Celsius.
