Cogar,, math is not my strong point !!
Mart, because so many people are now posting dimensions in
metric is why I told you that Google "trick".
When someone posts a temperature of 12C (12 degrees centigrade) .... then just load Google as
a 2nd "window" and key in ..... convert 12c to f .... and hit the "return" key and it will immediately display "
12 = 53.6" ... or 53.6 degrees fahrenheit.
It "converts" either direction, ..... c to f, --- f to c, ... in(ches) to mi(les) --- mi to in,... bushels to pints, .... whatever.
Or if someone uses a word you are unfamiliar with just enter ..... define
?? .... and hit the "return" key
I keep Google "open" as a 2nd window just for the above purpose.
