Katy,

Glad you responded. I didn't / wouldn't reply to a Sock puppet. You're
both right but it plain to see that you have never dealt with those kind
of temperature up real close in actual working condiitions. In reality
you have to do them in you head and often right now. 9/5 or 5/9+32
doesn't lend itself to rapid Calc.

If you take that 9/5 and convert it to 2 rather than 1and 4/5 then 51 is
a very quick conversion to a 100 or a 101+32.

A real sailor's way of converting radio weather reports internationally
to from C to F without putting a Mike down or leaving a Helm. 5 degrees
difference in 128 is a very small error I can live with and no
calculator or paper necessary.

It a trick sailor's and boiler room firemen have been using for years.

Try it. It is a good way to talk Temp with your Canadian friends,

And by the way, I can also do the formular conversion in my head but its
slower but not as slow as getting a calculator and setting up.

Thank you for giving me a chance to reply to "Nellen" about practical
sailor's solution. Neal never need to use things like that at Anchor.
