About Temperature Units
Temperature is a physical quantity that expresses hot and cold. It is measured with a thermometer calibrated in one or more temperature scales. Different temperature scales are used around the world for various purposes.
Temperature Scales
- Celsius (°C): The most widely used temperature scale worldwide. In this scale, 0°C is the freezing point of water and 100°C is the boiling point of water at standard atmospheric pressure.
- Fahrenheit (°F): Commonly used in the United States. In this scale, 32°F is the freezing point of water and 212°F is the boiling point of water at standard atmospheric pressure.
- Kelvin (K): The SI base unit of temperature. It uses the same increment as Celsius but starts at absolute zero, which is -273.15°C. There is no degree symbol used with Kelvin.
- Rankine (°R): An absolute temperature scale that uses the Fahrenheit degree. 0°R is absolute zero, and a temperature difference of 1°R equals a temperature difference of 1°F.
Conversion Formulas
- Celsius to Fahrenheit: °F = (°C × 9/5) + 32
- Fahrenheit to Celsius: °C = (°F - 32) × 5/9
- Celsius to Kelvin: K = °C + 273.15
- Kelvin to Celsius: °C = K - 273.15
- Fahrenheit to Kelvin: K = (°F - 32) × 5/9 + 273.15
- Kelvin to Fahrenheit: °F = (K - 273.15) × 9/5 + 32
- Fahrenheit to Rankine: °R = °F + 459.67
- Rankine to Fahrenheit: °F = °R - 459.67
- Kelvin to Rankine: °R = K × 9/5
- Rankine to Kelvin: K = °R × 5/9
Important Temperature Points
- Absolute Zero: -273.15°C, 0K, -459.67°F, 0°R
- Freezing Point of Water: 0°C, 273.15K, 32°F, 491.67°R
- Room Temperature: ~20°C, ~293.15K, ~68°F, ~527.67°R
- Body Temperature: ~37°C, ~310.15K, ~98.6°F, ~558.27°R
- Boiling Point of Water: 100°C, 373.15K, 212°F, 671.67°R
- Equal Point: -40°C = -40°F
