A temperature unit converter is a tool for converting between different temperature units. Common temperature units include Celsius (°C), Fahrenheit (°F), Kelvin (K), and Rankine (°R). This tool is useful not only in daily life but also in scientific experiments, engineering, meteorology, and various other fields.

Temperature Unit Converter Terminology

Celsius Temperature (°C)

  • Definition: The Celsius temperature scale was proposed by Swedish astronomer Anders Celsius.
  • Reference Point: Sets the freezing point of water at 0°C and the boiling point at 100°C, divided into 100 equal parts.
  • Usage: Daily life, meteorology, and most scientific fields.

Fahrenheit Temperature (°F)

  • Definition: The Fahrenheit temperature scale was proposed by German physicist Gabriel Daniel Fahrenheit.
  • Reference Point: Sets the freezing point of water at 32°F and the boiling point at 212°F, divided into 180 equal parts.
  • Usage: Mainly used in the United States and some Commonwealth countries

Absolute Temperature (K)

  • Definition: Kelvin is the SI unit for measuring absolute temperature, based on absolute zero (0 K) where all thermal motion of matter stops.
  • Reference Point: Absolute zero is approximately -273.15°C.
  • Usage: Scientific and engineering fields, especially thermodynamics, physics, and astrophysics.

Rankine Temperature (°R)

  • Definition: The Rankine temperature scale was proposed by Scottish engineer and physicist William John Macquorn Rankine.
  • Reference Point: Like Fahrenheit, 0°R corresponds to absolute zero and has the same interval as Fahrenheit.
  • Usage: Mainly used in the United States, especially in thermodynamics and engineering.

Temperature Unit Conversion Formulas

Celsius (°C), Fahrenheit (°F), Kelvin (K), and Rankine (°R) each have their historical background and uses, and are appropriately used in specific fields. Understanding the conversion formulas between each unit allows for accurate temperature conversion.

  • Celsius to Fahrenheit: F = (9/5)C + 32
  • Celsius to Kelvin: K = C + 273.15
  • Celsius to Rankine: R = (9/5)(C + 273.15)

Example 1) Converting 25°C to Fahrenheit: F = (9/5) × 25 + 32 = 77°F
Example 2) Converting 25°C to Kelvin: K = 25 + 273.15 = 298.15K

  • Fahrenheit to Celsius: C = (5/9)(F – 32)
  • Fahrenheit to Kelvin: K = (5/9)(F – 32) + 273.15
  • Fahrenheit to Rankine: R = F + 459.67

Example 1) Converting 77°F to Celsius: C = (5/9) × (77 – 32) = 25°C
Example 2) Converting 77°F to Kelvin: K = (5/9) × (77 – 32) + 273.15 = 298.15K

  • Kelvin to Celsius: C = K – 273.15
  • Kelvin to Fahrenheit: F = (9/5)(K – 273.15) + 32
  • Kelvin to Rankine: R = (9/5)K

Example 1) Converting 298.15K to Celsius: C = 298.15 – 273.15 = 25°C
Example 2) Converting 298.15K to Fahrenheit: F = (9/5) × (298.15 – 273.15) + 32 = 77°F

  • Rankine to Celsius: C = (5/9)(R – 491.67)
  • Rankine to Fahrenheit: F = R – 459.67
  • Rankine to Kelvin: K = (5/9)R

Example 1) Converting 536.67R to Celsius: C = (5/9) × (536.67 – 491.67) = 25°C
Example 2) Converting 536.67R to Fahrenheit: F = 536.67 – 459.67 = 77°F
