The world's highest recorded air temperature is officially recognized by the World Meteorological Organization as 134°F (57.6°C) recorded at Death Valley, California, USA on 10 July 1913.

Note that this is in recorded history. Higher temperatures have occurred, of course, at different times during the 4.55 billion years of Earth's history.

Related Information:

El Azizia, Libya, held this record for 90 years, after recording a temperature of 136°F (58°C) on 13 September 1922. It was coincidentally also on 13 September of 2012 that this record was stripped by the World Meteorological Organization after a team of experts determined that there were enough questions surrounding this measurement that this temperature probably did not occur.

The temperature had been suspect in atmospheric science circles for a number of reasons. One being that the time of year is inconsistent with such a high reading. Also, the type and exposure of the measuring instruments cast doubt on the accuracy of the data. However, other temperatures in the same general area approach that maximum, especially in the cloudless southern Sahara, far from the moderating effects of water. Several links are provided below for more information on this process.

Other Earth Temperature Highs:

The modern, most reliably recorded air temperature in the world was 129.2°F (54.0°C) at Death Valley on 30 June 2013.

The highest naturally occurring temperature (at Earth's core) is higher than the melting point of iron and is estimated to be approximately 5000°C.

The highest temperature ever created in a laboratory experiment: Scientists, using the Z machine, have produced plasma at temperatures of more than 2 billion degrees Kelvin (3.6 billion degrees F) at Sandia National Laboratories, located near Albuquerque New Mexico.

Dasht-e Lut, a desert in southeastern Iran, was identified as having the hottest surface temperature (not air temperature) of 70.7 degrees C (159 degrees F) This was only during the years of study in 2004 and 2005 by MODIS, which is a satellite remote sensor, mounted on NASA satellites Aqua and Terra.

Caveats to the Above:

Modern measuring methods, instruments, and techniques are more sophisticated and standardized today. Example: The World Meteorological Organization, recommends that air temperatures be measured at a height of 1.25 to 2 meters (which is approximately 4 feet, 1.2 inches to 6 feet, 6.7 inches) above ground level.

The most likely places on Earth for record high temperatures are in depressions in desert regions, especially in areas below sea level. The Dallol (Danakil) Depression in Africa (Ethiopia), Death Valley in USA, and the area around Lake Eyre in Australia are likely candidates. However, the Gobi Desert's temperatures, while far from any ocean, are mitigated by altitude. The Dallol Depression had a weather station for a short while (only a few years). It was run by a mining company, and wasn't there long enough to measure an extreme maximum to beat the Libyan record. It did however, measure very high mean average temperatures while it operated.

The thing to remember about very hot places is that data is sparse. This is because very few people with high levels of technology stay in these places for long. The environment of the Dallol Depression is hostile to human life. 135

Use this basic formula:

F = 9/5 C + 32

Temperature Fahrenheit = (9/5 x Temperature Celsius) + 32

The reverse formula is C = 5/9 (F - 32)

Temperature Celsius = 5/9 (Temperature Fahrenheit - 32)

Another formula:

°C = (°F - 32)/1.8

°F = (1.8 x °C) + 32

Another method:

F to C: Deduct 32, then multiply by 5, then divide by 9

C to F: Multiply by 9, then divide by 5, then add 32
Use this equation to convert degrees Fahrenheit (ºF) to degrees Celsius/Centigrade (ºC): [°C] = ([°F] - 32) × 0.556

°Celsius (or °Centigrade) to °Fahrenheit: [°F] = [°C] × 1.8 + 32

40 °C is equal to 104 °F

The conversion formula is Fahrenheit temperature = (9/5 x Celsius temperature)+ 32
40 degree Celsius = 104 degree Fahrenheit

20°C is equal to 68°F

The conversion formula is °F = (9/5 °C)+ 32

-------------------------------

F = [20 * (9/5)] + 32

F = 36 + 32

F = 68.
It's easy to convert from Celsius to Fahrenheit by yourself. Tf = (9/5)*Tc+32, where Tc = temperature in degrees Celsius, Tf = temperature in degrees Fahrenheit.20 C is 68 F.
20 degrees Celsius is 68 degrees Fahrenheit.
Conversion from Celsius to Fahrenheit is done in three steps:

1. Multiply value in degrees Celsius by 9.

2. Divide result of step 1 by 5.

3. Add 32 to result of step 2.

Conversion formula: [°F] = [°C] * 9 / 5 + 32 = 20 * 9 / 5 + 32 = 68 °F
68 F

This is a monstrously difficult question because Neptune is composed mostly of gas with a small core of rock.

It has been estimated that the temperature in the core is on the order of 7,000 °C, which is comparable to Earth's core or the surface of the Sun.

The mean atmospheric temperature on Neptune is as low as 218 °C (55.1 K) at the cloud tops and about -200 °C (72 K) at the pressure level equal to 1 Earth atmosphere.

Compare this to Uranus, which is a bit smaller but is closer to the sun. Uranus is a chilly -224 °C (49 K). Neptune is a long, long way from the sun, and very little energy gets there. But because it is as "warm" as it is, it is thought to have a core that is still generating heat.

That leaves us to make calculations and make an assessment as to why things are as we see them. We can figure out the amount of light Neptune gets, look at how much is reflected and how much is absorbed, and then look at its temperature. Some "extra heat" must be coming from somewhere, and the core is thought to be generating it. We really can't come up with a "surface temperature" per se for Neptune because of its structure. Wikipedia has more information, including a cutaway drawing of Neptune so you can see "into" this gas giant.
