The Climate of Tamil Nadu, India is generally tropical and features fairly hot temperatures over the year except during the monsoon seasons. The city of Chennai lies on the thermal equator, [1] which means Chennai and Tamil Nadu does not have that much temperature variation.
The highest recorded temperature was 45 °C (113 °F) on 31 May 2003. [8] The coldest time of the year is in December–January, with average temperature of 19–25 °C (66–77 °F) and the lowest recorded temperature of 13.9 °C (57.0 °F) on 11 December 1895 and 29 January 1905. [9] The average annual rainfall is about 1,400 mm (55 in).
Temperature is usually measured in degrees Celsius (°C), Kelvin (K), or degrees Fahrenheit (°F). If expressed in kelvins, then the symbol T a, if expressed in Celsius or Fahrenheit, then the symbol is t a. When measuring dry-bulb temperature, care should be taken to prevent the sensor from being subjected to radiation from neighbouring heat ...
In 1714, Gabriel Fahrenheit created a reliable scale for measuring temperature with a mercury-type thermometer. [46] In 1742, Anders Celsius, a Swedish astronomer, proposed the "centigrade" temperature scale, the predecessor of the current Celsius scale. [47] In 1783, the first hair hygrometer was demonstrated by Horace-Bénédict de Saussure.
Converting units of temperature differences (also referred to as temperature deltas) is not the same as converting absolute temperature values, and different formulae must be used. To convert a delta temperature from degrees Fahrenheit to degrees Celsius, the formula is {Δ T } °F = 9 / 5 {Δ T } °C .
Here, f is the value in degrees Fahrenheit, c the value in degrees Celsius, and k the value in kelvins: f °F to c °C: c = f − 32 / 1.8 c °C to f °F: f = c × 1.8 + 32; f °F to k K: k = f + 459.67 / 1.8 k K to f °F: f = k × 1.8 − 459.67; There is also an exact conversion between Celsius and Fahrenheit scales making use ...
A temperature gradient is a physical quantity that describes in which direction and at what rate the temperature changes the most rapidly around a particular location. The temperature spatial gradient is a vector quantity with dimension of temperature difference per unit length. The SI unit is kelvin per meter (K/m).
The hottest time of the year is from April to June with an average temperature of 35–40 °C (95–104 °F). [65] The highest recorded temperature was 45 °C (113 °F) on 31 May 2003. [66] The coldest time of the year is in December–January, with average temperature of 19–25 °C (66–77 °F) and the lowest recorded temperature of 13.9 °C ...
