🔢 Key Temperature Conversion Formulas

1. Celsius to Fahrenheit

°F=(°C×95)+32°F=(°C×59​)+32

Example: Convert 25°C to Fahrenheit25°C×95=45→45+32=77°F25°C×59​=45→45+32=77°F

2. Fahrenheit to Celsius

°C=(°F−32)×59°C=(°F−32)×95​

Example: Convert 98.6°F to Celsius(98.6−32)×59≈37°C(98.6−32)×95​≈37°C

3. Celsius to Kelvin

K=°C+273.15K=°C+273.15

Example: Convert 0°C to Kelvin0+273.15=273.15K0+273.15=273.15K

4. Kelvin to Celsius

°C=K−273.15°C=K−273.15

Example: Convert 300K to Celsius300−273.15≈26.85°C300−273.15≈26.85°C

5. Fahrenheit to Kelvin

K=(°F−32)×59+273.15K=(°F−32)×95​+273.15

Example: Convert 212°F to Kelvin(212−32)×59+273.15≈373.15K(212−32)×95​+273.15≈373.15K

6. Rankine to Celsius

°C=(°R−491.67)×59°C=(°R−491.67)×95​

Example: Convert 500°R to Celsius(500−491.67)×59≈4.63°C(500−491.67)×95​≈4.63°C
