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.<a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a> </p><p>Some numbers in this table have been rounded. </p> <h3>Graphical representation</h3> <table><tbody><tr><td colspan="10" rowspan="5"></td><td><a href="/facts/Rankine_scale/ya5sNd2C">Rankine</a> (°R)</td></tr><tr><td><a href="/facts/Kelvin/E3trzC4C">Kelvin</a> (K)</td></tr><tr><td><a href="/facts/Fahrenheit/2TVmyJod">Fahrenheit</a> (°F)</td></tr><tr><td><a href="/facts/Celsius/okAEu1CA">Celsius</a> (°C)<a href="/facts/R%25C3%25A9aumur_scale/p8C8o5vw">Réaumur</a> (°Ré)<a href="/facts/R%25C3%25B8mer_scale/37X1QjrX">Rømer</a> (°Rø)<a href="/facts/Newton_scale/InulHAwx">Newton</a> (°N)</td></tr><tr><td><a href="/facts/Delisle_scale/x6TXvR4n">Delisle</a> (°D)</td></tr><tr><td> </td><td><a href="/facts/Absolute_zero/U3UyPl2K">Absolute zero</a></td><td><a href="/facts/Lowest_temperature_recorded_on_Earth/6pQUuwFw">Lowest recorded surface temperature on Earth</a><a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a></td><td><a href="/facts/Fahrenheit/2TVmyJod">Fahrenheit's ice/water/salt mixture</a></td><td><a href="/facts/Melting_point/MY0w0h0k">Melting point</a> of ice (at <a href="/facts/Standard_conditions_for_temperature_and_pressure/JhJv9KFJ">standard pressure</a>)</td><td>Average surface temperature on Earth (15 °C)</td><td>Average <a href="/facts/Human_body_temperature/zbWKsEhF">human body temperature</a> (37 °C)</td><td><a href="/facts/Highest_temperature_recorded_on_Earth/SWqkLa9g">Highest recorded surface temperature on Earth</a><a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a></td><td><a href="/facts/Boiling_point/E2BK9QoS">Boiling point</a> of water (at standard pressure)</td><td> </td><td> </td></tr></tbody></table> <h2 id="conversion-table-between-the-different-temperature-units">Conversion table between the different temperature units</h2> <h2 id="converting-units-of-temperature-differences">Converting units of temperature differences</h2> <p>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. </p><p>To convert a delta temperature from degrees Fahrenheit to degrees Celsius, the formula is {Δ<i>T</i>}°F = 9/5{Δ<i>T</i>}°C. </p><p>To convert a delta temperature from degrees Celsius to kelvin, it is 1:1 ({Δ<i>T</i>}°C = {Δ<i>T</i>}K). </p> <h2 id="see-also">See also</h2> <ul><li><a href="/facts/Outline_of_metrology_and_measurement/r7vjUgk4">Outline of metrology and measurement</a></li> <li><a href="/facts/Degree_of_frost/MyjBpmIN">Degree of frost</a></li> <li><a href="/facts/Conversion_of_units/BY9Az4t6">Conversion of units</a></li> <li><a href="/facts/Gas_mark/woVC9M4e">Gas mark</a></li></ul> <h2 id="notes-and-references">Notes and references</h2> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>The Coldest Inhabited Places on Earth; researchers of the Vostok Station recorded the coldest known temperature on Earth on July 21st 1983: −89.2 °C (−128.6 °F). <a href="https://www.expertsure.com/2008/12/14/the-coldest-inhabited-places-on-earth/" target="_blank">https://www.expertsure.com/2008/12/14/the-coldest-inhabited-places-on-earth/</a> <a href="#fnref:1" class="footnote-back-ref">↩</a></p></li> <li id="fn:2"><p>The Coldest Inhabited Places on Earth; researchers of the Vostok Station recorded the coldest known temperature on Earth on July 21st 1983: −89.2 °C (−128.6 °F). <a href="https://www.expertsure.com/2008/12/14/the-coldest-inhabited-places-on-earth/" target="_blank">https://www.expertsure.com/2008/12/14/the-coldest-inhabited-places-on-earth/</a> <a href="#fnref:2" class="footnote-back-ref">↩</a></p></li> <li id="fn:3"><p>The Coldest Inhabited Places on Earth; researchers of the Vostok Station recorded the coldest known temperature on Earth on July 21st 1983: −89.2 °C (−128.6 °F). <a href="https://www.expertsure.com/2008/12/14/the-coldest-inhabited-places-on-earth/" target="_blank">https://www.expertsure.com/2008/12/14/the-coldest-inhabited-places-on-earth/</a> <a href="#fnref:3" class="footnote-back-ref">↩</a></p></li> <li id="fn:4"><p>"World: Highest Temperature".
