Frequently Asked Questions
How do I convert Celsius to Fahrenheit?
To convert Celsius to Fahrenheit, use Fahrenheit = Celsius × 1.8 + 32. For example, 1 Celsius = 33.8 Fahrenheit. Type any value above and the answer updates as you type.
What is the formula to convert Celsius to Fahrenheit?
°F = °C × 9/5 + 32 (multiply by 1.8, then add 32). For example: 0 Celsius = 32 Fahrenheit, 37 Celsius = 98.6 Fahrenheit, 100 Celsius = 212 Fahrenheit.
What is the formula to convert Fahrenheit to Celsius?
°C = (°F − 32) × 5/9 (subtract 32, then divide by 1.8). For example: 0 Fahrenheit = -17.7778 Celsius, 37 Fahrenheit = 2.77778 Celsius, 100 Fahrenheit = 37.7778 Celsius.
What is the formula to convert Celsius to kelvin?
K = °C + 273.15. For example: 0 Celsius = 273.15 kelvin, 37 Celsius = 310.15 kelvin, 100 Celsius = 373.15 kelvin.
What is the formula to convert kelvin to Celsius?
°C = K − 273.15. For example: 0 kelvin = -273.15 Celsius, 37 kelvin = -236.15 Celsius, 100 kelvin = -173.15 Celsius.
What is the formula to convert Fahrenheit to kelvin?
K = (°F − 32) × 5/9 + 273.15. For example: 0 Fahrenheit = 255.372 kelvin, 37 Fahrenheit = 275.928 kelvin, 100 Fahrenheit = 310.928 kelvin.
What is the formula to convert Rankine to Fahrenheit?
°F = °R − 459.67. For example: 0 Rankine = -459.67 Fahrenheit, 37 Rankine = -422.67 Fahrenheit, 100 Rankine = -359.67 Fahrenheit.
What is the formula to convert kelvin to Fahrenheit?
°F = (K − 273.15) × 9/5 + 32. For example: 0 kelvin = -459.67 Fahrenheit, 37 kelvin = -393.07 Fahrenheit, 100 kelvin = -279.67 Fahrenheit.
What is the base unit for temperature conversions?
