jiminy crickets: its fucking freezing!

The notion that counting the chirps of crickets can serve as an informal way of working out the temperature is not new — in 1897, physicist Amos Dolbear proposed the reverse of that idea, stating outdoor temperature determined the number of cricket calls one would hear. Over the years, his way of looking at this relationship was turned on its head — people now count the chirps to get the temp rather than consult the thermometer to figure out how many cricket calls they will hear.

We've encountered a variety of "cricket chirp thermometer formulas" over the years. One specifies counting the chirps over a 40-second interval, then adding 38 to that number to achieve the current temperature. Another say it's chirps over 14 seconds then add 38. Yet a third says it's number of chirps heard in 15 seconds then add 48.

The formula endorsed by The Old Farmer's Almanac seems the most reliable. Says that esteemed tome:

To convert cricket chirps to degrees Fahrenheit, count number of chirps in 14 seconds then add 40 to get temperature.

Example: 30 chirps + 40 = 70° F

To convert cricket chirps to degrees Celsius, count number of chirps in 25 seconds, divide by 3, then add 4 to get temperature.

Example: 48 chirps ÷ 3 + 4 = 20° C
