To convert a temperature from Celsius to Fahrenheit, you can use the following formula:

°F = (°C × 9/5) + 32

Substitute the given temperature (°C = 45.1) into the formula:

°F = (45.1 × 9/5) + 32

°F = (81.18 ÷ 5) + 32

°F = 16.236 + 32

°F ≈ 47.236

Therefore, 45.1 degrees Celsius is approximately equal to 47.236 degrees Fahrenheit.
