Final answer:
The equivalent temperature in Celsius to 145°F is 63°C (Option 1).
Step-by-step explanation:
To convert temperature from Fahrenheit to Celsius, we can use the formula: C = (F - 32) / 1.8. The temperature of 145°F when converted to Celsius is done by first subtracting 32 from the Fahrenheit value and then dividing the result by 1.8, as the conversion formula is C = (F - 32) × 5/9. Following the formula:
C = (145 - 32) × 5/9
C = 113 × 5/9
C = 62.777...
Rounded to the nearest whole number, this gives us 63°C. Therefore, the equivalent temperature in Celsius to 145°F is 63°C, which corresponds to option 1.
