Temperature Unit Conversion
A precise tool.
What is the Temperature Unit Conversion & How does it work?
Temperature is a measure of the average kinetic energy of particles in a substance. The Celsius (°C) scale sets the freezing point of water at 0 and the boiling point at 100, while the Fahrenheit (°F) scale places these milestones at 32 and 212 respectively. The Kelvin (K) scale is an absolute thermodynamic scale that starts at absolute zero, the theoretical point where molecular motion ceases. One kelvin increment is exactly the same size as one degree Celsius, making conversion between K and °C a simple offset. The Rankine (°R) scale mirrors Fahrenheit but begins at absolute zero; each degree Rankine equals one degree Fahrenheit. Conversions among these four units rely on linear relationships that can be expressed with a single intermediate step through Celsius or Kelvin.
F = C times frac{9}{5} + 32
F = Fahrenheit temperature, C = Celsius temperature

Frequently Asked Questions
How do I convert 25°C to Fahrenheit?
To convert 25°C to Fahrenheit, use the formula: (°C × 9/5) + 32. So, 25°C is equal to 77°F.
What is the boiling point of water in Kelvin?
The boiling point of water is 100°C or 212°F, which converts to 373.15 Kelvin.
How do I convert Fahrenheit to Celsius?
To convert Fahrenheit to Celsius, use the formula: (°F – 32) × 5/9. For example, 68°F is equal to 20°C.
What is absolute zero in Celsius and Fahrenheit?
Absolute zero is -273.15°C or -459.67°F.
How do I convert Kelvin to Celsius?
To convert Kelvin to Celsius, subtract 273.15 from the Kelvin temperature. For example, 300K is equal to 26.85°C.
What is the relationship between Celsius and Kelvin?
Celsius and Kelvin have the same size increment, with 0°C being equivalent to 273.15K.
How do I convert 30°F to Kelvin?
First, convert 30°F to Celsius using (°F – 32) × 5/9, which gives you -1.11°C. Then, add 273.15 to get the Kelvin equivalent: 272.04K.
