* Normal human body temperature is 36.8 °C ±0.7 °C, or 98.2 °F ±1.3 °F. The commonly given value 98.6 °F is simply the exact conversion of the nineteenth-century German standard of 37 °C. Since it does not list an acceptable range, it could therefore be said to have excess (invalid) precision.
Unlike the degree Fahrenheit and degree Celsius, the kelvin is no longer referred to or written as a degree (but was before 1967 [1] [2] [3]). The kelvin is the primary unit of temperature measurement in the physical sciences, but is often used in conjunction with the degree Celsius, which has the same magnitude. Other scales of temperature:
Anders Celsius's original thermometer used a reversed scale, with 100 as the freezing point and 0 as the boiling point of water.. In 1742, Swedish astronomer Anders Celsius (1701–1744) created a temperature scale that was the reverse of the scale now known as "Celsius": 0 represented the boiling point of water, while 100 represented the freezing point of water.

In humans, the average internal temperature is widely accepted to be 37 °C (98.6 °F), a "normal" temperature established in the 1800s. But newer studies show that average internal temperature for men and women is 36.4 °C (97.5 °F). [10] No person always has exactly the same temperature at every moment of the day.
He is known for his measurement of mean normal human body temperature of 37 °C (98.6 °F), now known more accurately to be about 36.8 °C (98.2 °F). [1]
−69.6 °C: −93.3 °F: Coldest officially recorded air temperature in the Northern Hemisphere at Klinck AWS, Greenland (Denmark) on 1991-12-22 [18] 205.5 K: −67.7 °C: −89.9 °F: Coldest officially recorded air temperature on the Eurasian continent at Oymyakon, USSR on 6 February 1933 [19] [full citation needed] 210 K: −63 °C: −80 °F
When converting a temperature interval between the Fahrenheit and Celsius scales, only the ratio is used, without any constant (in this case, the interval has the same numeric value in kelvins as in degrees Celsius): f °F to c °C or k K: c = k = f / 1.8 c °C or k K to f °F: f = c × 1.8 = k × 1.8
Studies from Nigeria show a comfortable temperature range of 26–28 °C (79–82 °F), comfortably cool 24–26 °C (75–79 °F) and comfortably warm 28–30 °C (82–86 °F). [4] A field study conducted in Hyderabad, India returned a comfort band of 26–32.45 °C (79–90 °F) with a mean of 29.23 °C (85 °F). [ 5 ]
