I went to the meeting on STEM this evening. The new magnet school is still under construction for grades K through 5 only. Metric units will be taught, but not exclusively. Students will begin by tracing their feet and comparing the lengths with the footprints of classmates. There were no measuri

While technically correct, 0.7 mm/cm looks a little weird.  Perhaps we should all use 70 mm/m, etc. 9Iit gets the prefix out of the denominator, eliminates the decimal for reasonable accuracy, etc. --- On Wed, 2/16/11, Pat Naughtin wrote: From: Pat Naughtin Subject: [USMA:49874] Re: Snow rat

John Steele points out that my mental math needs some WD-40 to get loosened back up. Make those figures 0.7 mm/cm, etc. Thanks again, John. Jim On 2011-02-16 1444, James R. Frysinger wrote: Interesting. The data in this article jibe well with the sparse data I collected. I had stated here ea

Interesting. The data in this article jibe well with the sparse data I collected. I had stated here earlier that my observations were averaging in the order of 7 mm/cm to 8 mm/cm of rain to snow. The annual data given on page 11 of this report (13 cm of snow to 1 cm water equivalent) work out t

When I lived in Canada, we sometimes would grade our snow as slushy, fluffy, crunchy, squeaky. Slushy - 0 to -3. Fluffy - -3 to -12. Crunchy - -12 to -25. Squeaky - anything below -25. John F-L - Original Message - From: Pat Naughtin To: U.S. Metric Association Sent: Wednesda

As an avid skier, I pay close attention to the temperature of the storm - as colder storms yield lighter, fluffier powder. Optimal conditions would be a relatively cold storm at night, with clear skies during the day. (We call this a blue-bird powder day). In fact, I am headed to Whistler, Brit
