Why do we use Celcius system here and why the Fahrenheit in US?

It's a cultural and an economic thing.\n\nHistorically Canada and the US acquired our measurement systems from England, which was highly influenced by the Germanic peoples, hence the attraction to "Fahrenheit".\n\nEngland, however was under economic pressure to trade with the other European countries (nearness) where the metric system and Celcius (both French origin) has been used. The English would not have accepted anything French if they could have avoided it, but money talks, and there was trade to be increased if England used the European systems more. Canada, being more closely tied to England than is the US, followed England's direction and used the metric more. That Canada has a significant French population has made a difference also I am sure.\n\nThe U. S., however, developed industrialy more rapidly than Canada, and did not follow the direction of England. We did not feel the economic pressures that England felt because we had more natural resources and were more self sufficient in our industrial production. Unlike Canada, the US was free of any ties to England, and with its fleet of merchant vessels found outlets for her manufactured products in more distant countries; and we cared less than England about the European markets. So we have stuck with the Fahrenheit thermometer, and the inch, foot, yard, mile, pound, ton system in practice, although we say we are changing over to the SI system.\n\nScience in the US uses the SI system, while much of the engineering application remains in the foot and pound system. We have tried and are still trying to change fully to the SI system, as witnessed by the nuts and bolts on our cars which are half in SI units, and half in the English, but industry is reluctant to change when it costs unrecoverable money to do so.

That isn't the real reason.\n\nCities are gigantic heat sinks.  The buildings and streets absorb vast amounts of heat during the daylight and release it at night or when it is cold.  Cities generate a lot of heat also.

The thermometers we use today are different than the ones Galileo may have used. There is usually a bulb at the base of the thermometer with a long glass tube stretching out the top. Early thermometers used water, but because water freezes there was no way to measure temperatures less than the freezing point of water. So, alcohol, which freezes at temperature below the point where water freezes, was used. \n\nThe red colored or silver line in the middle of the thermometer moves up and down depending on the temperature. The thermometer measures temperatures in Fahrenheit, Celsius and another scale called Kelvin. Fahrenheit is used mostly in the United States, and most of the rest of the world uses Celsius. Kelvin is used by scientists. \n\nThe most common rain gauge used today by official forecasters and airports was invented over 100 years ago. As you can see in the graphic, it consists of a large cylinder with a funnel and a smaller measuring tube inside of it. The official rain gauge has a tall cylinder with a funnel at the top that collects water into a measuring tube that has exactly one-tenth the cross sectional area of the top of the funnel. The reason for the smaller measuring tube is so that more precise precipitation measurements can be made due to the exaggeration of the height of water in the tube. For example, one-tenth of an inch of rainfall would actually fill an inch of the measuring tube. A special measuring stick inserted into the measuring tube takes into account the vertical scale exaggeration. This exaggeration allows meteorologists to make very precise measurements to one-hundredth of an inch. The official rain gauge measures up to an inch of rain in the inter tube. If rainfall exceeds 1 inch, water overflows into the cylinder surrounding the measuring tube. The observer takes the water in the cylinder and very carefully pours it into the measuring tube after emptying the tube. The observer then adds 1 inch to the measurement of water in the cylinder to obtain the final rainfall amount. (One inch is the amount in the inner tube before spilling over into the outer cylinder) \n\nMeasuring Precipitation in the form of Hail or Snow requires the removal of the inner tube and the funnel. Ice and snow is collected in the outer cylinder and then melted for a Precipitation reading. \n\nRain Gauge --

Temperature is the physical property of a system that underlies the common notions of "hot" and "cold"; something that is hotter has the greater temperature. Temperature arises from the random microscopic motions of the atomic and subatomic constituents of matter. The temperature is related to the average energy of these microscopic motions. It is a fundamental parameter in thermodynamics.\n\nTemperature is measured with thermometers that may be calibrated to a variety of temperature scales. Throughout the world (except for the U.S.), the Celsius scale is universally used for most temperature measuring purposes.

you could have just googled this...\n\nanyway\n\nC = (F-32) / 1.8\n\nF = (C x 1.8) + 32\n\nwhere \nF = degrees Fahrenheit\nC = degrees Celcius

same reason the U.S. won't change measuring systems. We like what we know. Someone once told me that the U.S. and Sri Lanka are the only countries that use our measuring system, yet it appears on nearly everything. As long as you coddle us and let us have our way we'll keep doing it.\n\nI'd never seen yyyy-mm-dd before. We use the mm/dd/yy system in the US and I'd seen dd/mm/yy in my Spanish classes (which was very confusing the first time I saw it because it was talking about october 11 which I read as november 10.)

Because it traps the heat from the sun and earth from escaping back into space, thereby making the planet warmer.  It's called the greenhouse affect.  That also causes more clouds and rain and blocking the suns heat making it cooler.....\n\nThere is still much debate as to how much is really caused by us, and how much is natural no matter what.  Our Earth has been everything from a molten planet to a glacier planet in it's 5 billion years, and we have only been recording temperature for about 150 years.  \n\nNobody can say anything for sure, too many variables, all we do know is it has been getting a little warmer the last few decades.  Anyone who says they know for sure why is not being honest with you or themselves.  It's a political issue now, and you know what that means, lies, lies lies.

Fahrenheit  to Celsius °C = (°F – 32) / 1.8\nCelsius to Fahrenheit °F = °C × 1.8 + 32

Celsius is the world meteorological standard.  Kelvins are the scientific standard.  Fahrenheit is a non-standard and archaic unit used by Americans only.

The Weather Underground displays temperatures in both Farenheit and Celsius.  Please see below.

because in Europe..., they use the Metric system

I think the temperatures are too extreme for life as we know it. There is a four hundred degree ( Fahrenheit ) difference between night and day.

wtf why did you ask the same question as me?\n\nactually i was talking about fahrenheight as in temperature,so our questions are different, it's all good.
