°F = °C × 9/5 + 32 · K = °C + 273.15
What is a temperature converter? A temperature converter changes a temperature reading from one scale into another. This one converts between Celsius, Fahrenheit, and Kelvin — the three most common scales.
Multiply the Celsius value by 9/5 and add 32: °F = °C × 9/5 + 32. For example, 100°C = 100 × 9/5 + 32 = 212°F.
Add 273.15 to the Celsius value: K = °C + 273.15. For example, 100°C = 100 + 273.15 = 373.15 K.
Subtract 32 from the Fahrenheit value, then multiply by 5/9: °C = (°F − 32) × 5/9. For example, 212°F = (212 − 32) × 5/9 = 100°C.
