In Kanchanaburi Province, Thailand, in March and April, it gets into the (low ) forties, but upper thirties regularly...man, it's hot...(35 today)...
Chris: For most of the world Fahrenheit is the measure used, not Celsius.
I may be about to crawl out on a limb here, but who, besides America and Britain use Fahrenheit?...and I'd venture to say definitely not 'most'...
Be well...and cool... [Edited misattributed quote — Dhammanando]
Hello Ven. Appicchato, all,
Yes - you are correct. Thanks. Usage
In the United States the Fahrenheit system continues to be the accepted standard for non-scientific use. All other countries have adopted Celsius as the primary scale in use. Fahrenheit is sometimes used by older generations in English speaking countries, especially for measurement of higher temperatures. The United Kingdom has almost exclusively used the Celsius scale since the 1970s, with the notable exception that some broadcasters and publications still quote Fahrenheit air temperatures occasionally in weather forecasts, for the benefit of generations born before about 1950, and air-temperature thermometers sold still show both scales for the same reason.
The Fahrenheit scale was the primary temperature standard for climatic, industrial and medical purposes in most English-speaking countries until the 1960s. In the late 1960s and 1970s, the Celsius (formerly Centigrade) scale was phased in by governments as part of the standardizing process of metrication.
Fahrenheit supporters assert its previous popularity was due to Fahrenheit’s user-friendliness. The unit of measure, being only 5⁄9 the size of the Celsius degree, permits more precise communication of measurements without resorting to fractional degrees. Also, the ambient air temperature in most inhabited regions of the world tends not to go far beyond the range of 0 °F to 100 °F: therefore, the Fahrenheit scale would reflect the perceived ambient temperatures, following 10-degree bands that emerge in the Fahrenheit system. Also, coincidentally, the smallest sensible temperature change averages one Fahrenheit degree; that is, the average person can just detect a temperature difference of a single degree.
But some Celsius supporters argue that their system can be just as natural; for example, they might say that 0–10 °C indicates cold, 10–20 °C mild, 20–30 °C warm and 30–40 °C hot. http://www.diffen.com/difference/Celsius_vs_Fahrenheit
