What is Temperature Conversion? Understanding Different Temperature Scales
Temperature conversion is the process of converting a temperature value from one scale to another. Different countries and scientific disciplines use different temperature measurement scales. This temperature converter tool allows you to quickly and accurately convert between seven different temperature scales: Celsius (metric standard), Fahrenheit (commonly used in USA), Kelvin (absolute temperature scale used in science), Rankine (engineering scale), Delisle (historical scale), Newton (early temperature scale), and Réaumur (historical European scale). Whether you need to convert Celsius to Fahrenheit for cooking, Kelvin for scientific calculations, or understand historical temperature scales, our temperature unit converter has you covered.
Temperature Scales & Their Applications
- •Celsius (°C)
The metric standard temperature scale. Water freezes at 0°C and boils at 100°C. Used worldwide for everyday temperature measurements, weather forecasts, and most scientific applications.
- •Fahrenheit (°F)
Primarily used in the United States and some Caribbean nations. Water freezes at 32°F and boils at 212°F. Commonly used in weather forecasting, cooking, and household temperature measurements.
- •Kelvin (K)
The absolute temperature scale used in physics and chemistry. 0 K is absolute zero (lowest possible temperature). Water freezes at 273.15 K and boils at 373.15 K. Essential for scientific and engineering calculations.
- •Rankine (°R)
An absolute temperature scale based on Fahrenheit intervals. Absolute zero is 0°R. Used in engineering, thermodynamics, and some technical fields, particularly in aerospace applications.
- •Delisle (°De)
A historical temperature scale created in 1732. Reversed scale where higher temperatures have lower values. Used historically in some European countries.
- •Newton (°N)
One of the earliest temperature scales, created by Isaac Newton. Water freezes at 0°N and boils at 33°N. Historically used but now largely obsolete in favor of modern scales.
- •Réaumur (°Ré)
A historical European temperature scale. Water freezes at 0°Ré and boils at 80°Ré. Mainly of historical interest now, occasionally used in specialized fields.
