What is a Temperature Interval Converter?
A temperature interval converter is a tool that converts temperature differences (not absolute temperatures) between Celsius, Fahrenheit, Kelvin, Rankine, and Réaumur scales. It is used in engineering, HVAC, and thermodynamics where temperature changes matter more than absolute values.
How to Convert Temperature Interval Units
Select the temperature interval unit you want to convert from and the target unit using the dropdown menus. Enter the temperature difference value and the converter instantly shows the equivalent interval. Remember: this converts differences, not absolute temperatures.
Temperature Interval Conversion Formulas
History of Temperature Interval Measurement
Temperature interval conversion differs from absolute temperature conversion because offsets do not apply. A 1°C interval equals 1 K but 1.8°F. This relationship was established when Fahrenheit and Celsius developed their scales in the 18th century. The Rankine scale uses Fahrenheit-sized degrees starting at absolute zero.
About This Temperature Interval Converter
This temperature interval converter supports 5 units: degree Celsius, degree Fahrenheit, kelvin, degree Rankine, and degree Réaumur. It converts temperature differences, not absolute temperatures, so no offset is applied.
Frequently Asked Questions
What is the difference between temperature and temperature interval?
Temperature is an absolute value (e.g., 20°C). Temperature interval is a difference between two temperatures (e.g., a 10°C rise). Interval conversion uses only the scale ratio, not the offset between scales.
How do I convert a Celsius interval to Fahrenheit?
Multiply the Celsius interval by 1.8 to get the Fahrenheit interval. For example, a 10°C temperature rise equals a 18°F temperature rise.
Is a 1°C interval the same as 1 kelvin?
Yes, a 1°C interval equals exactly 1 kelvin interval. The Celsius and Kelvin scales have the same degree size; they only differ in their zero points.
Why is temperature interval conversion different from temperature conversion?
Absolute temperature conversion requires adding/subtracting offsets (like +32 for °C to °F). Interval conversion only uses the ratio between degree sizes because the offset cancels out when subtracting two temperatures.
What is the Rankine scale?
The Rankine scale uses Fahrenheit-sized degrees but starts at absolute zero (0°R = -459.67°F). A 1°R interval equals a 1°F interval. It is used in some US engineering thermodynamics calculations.
