Formula Behind Temperature Conversion Calculator
Temperature conversion uses clear mathematical formulas: Celsius to Fahrenheit is (°C × 9/5) + 32, Celsius to Kelvin is (°C + 273.15), and Fahrenheit to Celsius is (°F − 32) × 5/9. From Fahrenheit to Kelvin: ((°F − 32) × 5/9) + 273.15, and Kelvin to Fahrenheit: ((K − 273.15) × 9/5) + 32. Each formula accurately adjusts for the scales' different reference points.

FAQs on Temperature Conversion Calculator – Convert Between Celsius, Fahrenheit & Kelvin
1. How do you convert a temperature from Celsius to Fahrenheit using the formula?
To convert from Celsius (°C) to Fahrenheit (°F), use the formula: °F = (°C × 9/5) + 32. First, multiply the Celsius temperature by 9/5 (or 1.8). Then, add 32 to the result to find the equivalent temperature in Fahrenheit.
2. What is the formula to convert a temperature from Fahrenheit to Celsius?
To convert a temperature from Fahrenheit (°F) to Celsius (°C), the correct formula is: °C = (°F - 32) × 5/9. You must first subtract 32 from the Fahrenheit temperature, and then multiply that result by 5/9.
3. How do you convert Celsius to Kelvin?
Converting from Celsius to Kelvin is a straightforward addition. The formula is K = °C + 273.15. Simply add 273.15 to the Celsius temperature to get the value in Kelvin. Note that the Kelvin scale does not use the degree (°) symbol.
4. Why is the Kelvin scale preferred for scientific calculations?
The Kelvin scale is preferred in science because it is an absolute thermodynamic scale. Its starting point, 0 K, represents absolute zero—the theoretical temperature at which all particle motion stops. This avoids negative numbers and allows for direct proportionality in many physics and chemistry laws, such as the Ideal Gas Law.
5. How do you convert directly from Fahrenheit to Kelvin?
To convert directly from Fahrenheit to Kelvin without first finding Celsius, you can use a combined formula: K = (°F - 32) × 5/9 + 273.15. This two-step process first converts the Fahrenheit value to its Celsius equivalent and then adds 273.15 to find the Kelvin temperature.
6. Is a 10-degree increase in Celsius the same as a 10-degree increase in Fahrenheit?
No, they are not the same. The size of one degree is different between the two scales. A temperature change of 1°C is equivalent to a change of 1.8°F. Therefore, a 10-degree increase in Celsius is equal to an 18-degree increase in Fahrenheit. However, a 1°C change is equal to a 1 K change.
7. At what temperature do the Celsius and Fahrenheit scales show the same reading?
The Celsius and Fahrenheit scales show the exact same reading at -40 degrees. At this unique point, -40°C is equal to -40°F. This is the only temperature at which the two scales intersect.
