Quick Calculation Tip
Celsius and Fahrenheit are equal at exactly -40°. Kelvin is the absolute temperature scale used in physics where 0K is absolute zero.
Understanding Temperature Scales
Temperature is a physical quantity that expresses hot and cold. It is the manifestation of thermal energy, present in all matter, which is the source of the occurrence of heat, a flow of energy, when a body is in contact with another that is colder.
In the modern world, different regions and scientific fields use different scales to measure this phenomenon. From the standard **Celsius** used globally to the **Fahrenheit** system in the US, and the absolute **Kelvin** scale used in physics, understanding the relationship between these measurements is essential for science, cooking, and global travel.
The Global Standard
Celsius (°C) is the most widely used scale. It is based on the freezing (0°) and boiling (100°) points of water at standard atmospheric pressure.
Scientific Precision
Kelvin (K) is the primary unit of temperature in the Physical Sciences. 0 Kelvin is **Absolute Zero**, where all molecular motion stops.
