    There is Decimal Time https://en.wikipedia.org/wiki/Decimal_time but metric time is actually a thing; but it's essentially just counting seconds and adding milli, deci, kilo- etc to the front to mean 0.001, 10, 1000 seconds, etc. It's most widely used in computing; on unix systems time is given as the number of seconds since Jan 1, 1970. That lead to the Y2038 problem where Time would stop and start over in 2038 because the 32-bit unsigned integer would roll back over to 0, kind of like the Mayan Calendar in 2012 (which was never *actually* 'the end of the world' to the mayans, but 'time to carve a new calendar!'). Fortunately we use a 64-bit integer, which put off solving the problem until later...MUCH later:

    "At 15:30:08 UTC on Sunday, 4 December 292277026596, 64-bit versions of the Unix time stamp cease to work, as it will overflow the largest value that can be held in a signed 64-bit number. This is nearly 22 times the estimated current age of the universe, which is 1.371010 years (13.7 billion)."

    Now THAT'S how you kick the can down the road...

    Fortunately, as the asteroid won't pass nearly as closely in 2021; it will remain 44 times more distant than the moon, or 10,471,577 miles. credit: NASA/JPL-Caltech). Just as fortunate, Eiffel Tower [1063'] is not 52013101185.8 X taller or it could be hit!
    Without a sample maple syrup jug [post 211], and calculate spacing, cannot predict that measurement, instead; roughly equivalent 165869779680 WD-40 spray tubes laid end to end.

    marksbug The celcius thing is easy, minus 32 then half it for fathom height lol and double it and add 32 for celcimus, very crude but works. The difference will never be seen from an Alaskan tramway.

    so 10 deg C = 20 + 32 = 52 deg F or 60 deg F = 60-32 = 28/2 =14 deg C

    It always been a best gestimate for me.

    Close enough for a barn door I'd say. C=(F-32)*5/9, F=(C*9/5)+32, C=F*1.8+32, F=(C-32)/1.8

    This brought back memories of walking home from school in 1969 working out the conversions as we had just changed to metrickery. The Metric system is far easier to use that's for sure. Water boils at 100 degrees and freezes at 0 degrees in most circumstances.
