Temperature Facts & History
Absolute zero (0 K or −273.15°C) is the lowest possible temperature where atomic motion nearly stops.
The Celsius scale was originally reversed, with 0° as boiling and 100° as freezing.
The surface of the Sun has a temperature of about 5,505°C, while its core exceeds 15 million°C.
The Fahrenheit scale was based on a brine mixture of salt, ice, and water.
−40°C is the only temperature where Celsius and Fahrenheit are equal.
The highest temperature recorded on Earth was 56.7°C in Death Valley, USA.
Frequently Asked Temperature Conversion Questions
What is absolute zero?
Absolute zero is 0 Kelvin (−273.15°C), the lowest possible temperature where atomic motion nearly stops.
How do you convert Celsius to Fahrenheit?
To convert Celsius to Fahrenheit, multiply the Celsius value by 9/5 and then add 32.
Why do scientists use Kelvin?
Kelvin is an absolute temperature scale starting at absolute zero, making it ideal for scientific calculations.
Why is −40°C the same as −40°F?
At −40 degrees, the Celsius and Fahrenheit conversion formulas intersect, making the values equal.
What temperature scale is used in cooking ovens?
Cooking ovens commonly use Celsius, Fahrenheit, or Gas Mark depending on the region.
