9/5(degrees C) + 32 equals ______.

9/5(degrees C) + 32 equals ______.

• A. Fahrenheit
• B. Celsius
• C. Kelvin
• D. Rankine

Answer: (A)

This uses the Celsius-to-Fahrenheit conversion: F = (9/5)C + 32. The expression given is exactly that form, with C representing degrees Celsius, so the result is a temperature expressed in Fahrenheit. For example, 0°C converts to 32°F, and 100°C converts to 212°F. The other scales aren’t produced by this formula: Celsius would report the same number in Celsius, while Kelvin and Rankine require different relationships to Celsius or Fahrenheit.
