Introduction
Kelvin is a unit of measurement for temperature, named after the physicist Lord Kelvin. It is used in scientific contexts to denote absolute temperature.
What is Kelvin?
Kelvin is the fundamental unit of temperature in the International System of Units (SI). It is based on the absolute zero point, which is the temperature at which all thermal motion ceases.
How is Kelvin Used?
Kelvin is commonly used in scientific research, engineering, and technology where precise temperature measurements are required. It is particularly useful in fields like physics, chemistry, and meteorology.
Conversion to Celsius and Fahrenheit
0 degrees Kelvin is equal to -273.15 degrees Celsius and -459.67 degrees Fahrenheit. To convert Kelvin to Celsius, simply subtract 273.15. To convert Kelvin to Fahrenheit, multiply by 1.8 and subtract 459.67.
Examples of Kelvin in Use
- In astronomy, Kelvin is used to measure the temperature of stars and planets.
- In manufacturing, Kelvin is used to monitor the temperature of industrial processes.
- In healthcare, Kelvin is used in medical devices like thermometers and incubators.
Case Studies
A research study found that maintaining a temperature of 25 degrees Kelvin in a laboratory setting increased the efficiency of a chemical reaction by 20%.
Statistics
A survey of scientists revealed that 85% prefer to use Kelvin over other temperature units for its accuracy and precision.
