A temperature of 69.5 degrees Fahrenheit...

🔍 Key Concepts

• Relationship between the Fahrenheit and Rankine temperature scales • How to convert an absolute temperature scale (like Rankine or Kelvin) from its corresponding common scale (Fahrenheit or Celsius) • Remembering the numerical offset between Fahrenheit and Rankine when degrees are the same size

💭 Think About

• Ask yourself: Does converting from Fahrenheit to Rankine require changing the size of the degree, adding an offset, or both? • Think about what Rankine equals at 0°F and at 32°F—how does that help you find the conversion rule? • Once you know the conversion rule, carefully plug in 69.5°F and check whether your answer is reasonable compared to typical room temperature in Rankine.

✅ Before You Answer

• Verify the formula you’re using to convert from °F to °R is correct before doing any arithmetic. • Check that you added (or subtracted) the correct numerical offset and did not accidentally multiply when you should add, or vice versa. • After computing, confirm your result is greater than 0°R and roughly in the same range that room temperature (about 70°F) would be in Rankine.
