I have a digital thermometer that has indoor and outdoor detectors. It cost me DM 29 a few years ago I bought it while working in Germany. It is a wonderful teaching tool the ADC inside the thermometer is tuned to 1 bit = 0.1°C. It also has a °C/°F selector switch. Some internal electronics converts the celsius reading to Fahrenheit, but the Fahrenheit output as has a four steps of 0.2 °F followed by a step of 0.1 °F!
In answer to Jerrys question domestic quality thermometers are readily available that measure to this accuracy, so one expects met office thermometers to do likewise _____ From: [email protected] [mailto:[email protected]] On Behalf Of Jeremiah MacGregor Sent: 31 January 2009 04:49 To: U.S. Metric Association Cc: U.S. Metric Association Subject: [USMA:42663] Re: Hot and dry Pat, Does Australia actually measure temperatures to tenths of a degree?

It was at 53° most of the match; at one point it read about 62° even thought its max was 60°. It was in the direct sun. Dear Kim, I've been watching the Australian Open on television and I really feel for the players having to experience these temperatures. Both Melbourne and Geelong (70 kilometres apart) have been experiencing near record temperatures for the last two days. In Geelong, the temperatures measured in the shade were: Wednesday 41.1 °C Thursday 45.5 °C And the prediction for today is for 43 °C The temperatures in the sun are much higher. An interesting point is that the roof on the Rod Laver Arena where the main matches are played is closed when the wet bulb thermometer reaches 28 °C as this thermometer reading takes into account humidity and wind speed as well as temperature.

In the next few days we expect the following temperatures: Tuesday 38 °C Wednesday 41 °C Thursday 40 °C Friday 40 °C Saturday 40 °C Sunday 30 °C See the article http://www.theage.com.au/national/melbourne-faces-worst-hot-spell-in-100-yea rs-20090126-7q0c.html for the details. Melbourne is the nearest big city to Geelong. Melbourne is 70 kilometres north-east of Geelong. You might recall the rhyme: Zero is freezing, 10 is not, 20 is pleasing, 30 is hot, 40 frying, 50 dying. I don't know who wrote the first three lines but I added the last two to consider Australian conditions. We live near the coast of the Southern Ocean but 200 kilometres inland from us you can expect the predicted temperatures to be about 3 °C hotter than here. Swan Hill, for example, will reach 44 °C on Wednesday and 43 °C on Thursday, Friday, and Saturday. It's amusing to see chatter in northern hemisphere media reports about 'global cooling'. You won't get much empathy for that position here in Australia as we are about to experience our second driest January in 159 years that is being topped off with this current heat wave. So far this month Geelong has had 0.4 millimetres of rain compared to a long term average of 35.6 millimetres for January.
