A story on the news last night brought back to mind what I knew as a kid. If you count the number of cricket chirps in 14 seconds and add 38, it will be the exact Fahrenheit temperature.

I never can remember the damn formula for converting F-to-C. So, for those enlightened countries that use the metric system, can some genetic scientist develop a Celsius cricket? Save a fortune on thermometers.

Our cats hunt down and eat all crickets around here, so a Celsius cricket wouldn’t help. Maybe one that could post it on the Web, so the cats didn’t hear…

The temperature in Fahrenheit is C x 14 + 38, where is C is the chirps per second. In Celsius, that’ll be (C x 14 + 38 - 32) x 5/9 == C x 8 + 3 (approximately).

So, for the Celsius cricket, count the number of chirps in 8 seconds and add 3.

Nothing to do with crickets but I surprised myself the other day when I took a dog’s temperature and discovered the thermometer was set to Celsius. Instead of sticking the thermometer up the dog’s butt again I just did the math, amazingly I remembered the formula without having to look it up.* So you never know, maybe you could remember the formula if you tried.

Oh man, Pleonast, I never fail to be astonished at the depth and bredth of knowledge that Dopers posses (or for the scientific term, "smartness). Thanks
