Temperature of McDonald’s Coffee, and Other Celsius Benchmarks

I am so done with cold weather. Northern Virginia had trouble breaking 40°F in January. Granted, we’re not International Falls, MN, where the temperature had trouble surpassing the legal drinking age, but I am still ready for spring.

In January 2005, I went skiing near Montreal. At the bottom of the mountain, a thermometer showed the temperature to be ‑25°C. Next to the thermometer was a sign announcing that the temperature at the top of the mountain was ‑20°C. My buddy said, “Quick, let’s get on the lift. It’s 5° warmer at the top.”

Really? If you can tell the difference between ‑25°C and ‑20°C, you’ve spent too much time in North Dakota.

Back home, I was telling a friend about the trip. I mentioned that it was ‑25° on the mountain. I failed to include the temperature scale, and she actually asked, “Celsius or Fahrenheit?” All I could think was, “Does it matter?” It was cold! C-O-L-D!

International travel can be tough if you need to continually convert between temperature scales. Here’s an annotated Celsius thermometer with some benchmarks:

A related trivia question for which very few folks know the answer (without computing it): At what temperature does degrees Celsius equal degrees Fahrenheit?

    When I was in high school, my parents sent me to Siberia for a semester. Not only do I know the temperature at which Celsius and Fahrenheit are the same (-40, for those keeping score at home), I have experienced it firsthand.

    Did they send you for a study abroad excursion, or was it punishment for being a bad kid?

    It was a study abroad program. My little high school in the middle of Iowa had an exchange program with a little high school in the middle of Siberia. I’m not really sure who go the shorter end of that stick. Which reminds me a a joke:

    Q: What is the only good thing to ever come out of Iowa [or insert other placename here]?
    A: Interstate 80. 😉
