Here's how to convert 300 degrees Fahrenheit (°F) to Celsius (°C):

Formula:

°C = (°F - 32) x 5/9

Calculation:

1. Subtract 32 from the Fahrenheit temperature: 300°F - 32 = 268

2. Multiply the result by 5/9: 268 x (5/9) = 148.89°C (approximately)

Therefore, 300 degrees Fahrenheit is approximately equal to 148.89 degrees Celsius.
