the answer:
Celsius Temperature Scale
This is a temperature scale where 0 degrees corresponds to the freezing point of water, and 100 degrees to its boiling point at standard atmospheric pressure. It is used in most countries worldwide and widely in scientific and everyday contexts. The scale was proposed in 1742 by the Swedish scientist Anders Celsius
How to Convert Celsius to Fahrenheit? Formula
To convert degrees from Celsius to Fahrenheit, multiply the initial number by 9, divide by 5, and then add 32. For example, 100°C * 9/5 = 180, 180 + 32= 212 °F.
Absolute Minimum Temperature in Fahrenheit
Absolute zero is the theoretical minimum temperature at which particles of matter cease all motion and possess no thermal energy. In the International System of Units (SI), absolute zero is defined as 0 Kelvin (K), which corresponds to -273.15 degrees Celsius or -459.67 degrees Fahrenheit. Absolute zero serves as the basis for many thermodynamic calculations and studies.
