To me, the most difficult part of the using the metric system day-to-day is getting used to the Celsius measure of temperature.
I changed the weather app on my phone more than a year ago so it’s much easier for me to use Celsius now, especially when you consider that 0° C is freezing. I know what freezing is, regardless of what system is employed. At the other end, 100° C is boiling instead of our 212° Fahrenheit. Since it’s slightly imprecise (compared to what we use now), some countries compensate by using decimal measures for temperature so it’s sometimes reported as 18.3° C, for example. (In Fahrenheit, 18° C could be anywhere between 64.4° to 66°. Okay granted, now that I look at that it looks pretty silly–the middle 60s are still the middle 60s. The decimal point doesn’t really help me decide how many clothes I should wear when I go outside…)
During my research for this documentary I found several rhymes to help people adjust to the “new” (at the time) metric measures. I used one of them during my previous presentation at the MidSchool Math conference last year but had to apologize since it hit me as a little clunky. I told my audience that I hadn’t had time to write something better.
Given that I’m presenting next month at the same conference (slightly different topic than last year) I decided I needed to do what I said I’d do and try to come with something I thought worked a little bit better.
The poem I presented last year:
This bothered me a little since the construction is not parallel…that third line throws me off and seems out of sync (not written by a poetry major perhaps?)
On the U.S. Metric Association pages:
A bit better but I thought I’d take a stab at it as well. Here’s what I came up with (original to the best of my knowledge):
At 30 it’s hot
At 20 it’s pleasing
At 10 it’s cold
And 0 it’s freezing
I think it works because “pleasing” and “freezing” rhymes, “hot” and “cold” in the second and third lines shows a decreasing sense of temperature (as do the rest of the rhymes I came across).
Hey, you tell me. When the U.S. decides to convert to the metric system, which poem is the easiest to remember for you? I’ll leave the poll open a couple of weeks and will use the most popular version as I move forward with my project.
Thanks for your participation!
