Temperature is the measure of heat within a system, indicating how hot or cold something is. This is a fundamental concept in science and daily life, influencing everything from weather to cooking. Temperature is typically measured in Celsius or Fahrenheit and helps us understand and control the environment around us, ensuring comfort, safety, and effective processes.
- Celsius: Widely used internationally, where 0°C is the freezing point of water and 100°C is its boiling point.
- Fahrenheit: Primarily used in the US, with 32°F as the freezing point and 212°F as the boiling point of water.
- Kelvin: Used mainly in scientific settings, where 0 K represents absolute zero, equivalent to -273.15°C.
- Rankine: Mainly used in engineering, particularly in the US, with 0°R representing absolute zero. Rankine degrees are similar to Kelvin but are based on the Fahrenheit scale.
