About Temperature Converter
Unlike most physical units of measurement that share a common proportional scale, temperature scales use distinct origin points (offsets) and degree step sizes.
• Celsius (°C): 0°C represents the freezing point of water, and 100°C represents its boiling point at sea level. • Fahrenheit (°F): 32°F is freezing point of water, and 212°F is boiling point. • Kelvin (K): The base unit of thermodynamic temperature where 0 K is Absolute Zero (−273.15°C). • Rankine (°R): The absolute temperature scale using Fahrenheit degree increments.
How to use Temperature Converter
- Type the value you want to convert.
- Choose the unit you are converting from and the unit you want, such as Celsius, Fahrenheit, Kelvin or Rankine.
- Read the converted value instantly. Swap the units to convert the other way.
- Copy the result, or check other units listed in the results grid.
Worked examples
Input: 25 °C to °F
Result: 77 °F.
Input: 98.6 °F to °C
Result: 37 °C.
Input: 0 K to °C
Result: -273.15 °C, absolute zero.
Background
Temperature scales differ in both the zero point and the size of a degree, so conversion needs an offset as well as a ratio. F = C x 9/5 + 32. K = C + 273.15. Rankine is Fahrenheit shifted to absolute zero: R = F + 459.67.
Because of the offset, you cannot convert a temperature difference the same way as a temperature. A 10-degree rise in Celsius is an 18-degree rise in Fahrenheit.
Common mistakes
- Doubling Celsius and adding 30 as a mental shortcut. It drifts at extremes.
- Applying the offset to a temperature difference.
- Entering values below absolute zero, which have no physical meaning.
