If a thermometer reads 80oC, what is the equivalent temperature in oF?

Correct Answer: Option D — 176oF

The conversion formula from Celsius to Fahrenheit is F = (C × 9/5) + 32. Applying this to 80°C: (80 × 1.8) + 32 equals 144 + 32, resulting in 176°F. This standard temperature conversion is essential for monitoring auxiliary system parameters like cooling water or lube oil temperatures during watchstanding duties.
