What is it?
Temperature conversion translates between Celsius (worldwide standard), Fahrenheit (used in the US), and Kelvin (SI unit for physics where 0 K is absolute zero). The formulas are F = C x 9/5 + 32 and K = C + 273.15.
How to use
Enter a temperature in Celsius. The calculator instantly shows the equivalent in both Fahrenheit and Kelvin. Water freezes at 0 degrees C (32 F, 273.15 K) and boils at 100 degrees C (212 F, 373.15 K).
Example scenario
Traveling to Europe and the forecast says 22 degrees C? That converts to 71.6 degrees F, a pleasant spring day. In science, room temperature of 25 degrees C equals 298.15 K.
Pro tip
Quick mental conversion from C to F: double the Celsius value, subtract 10%, then add 32. Example: 30 C -> 60 -> 54 -> 86 F (actual: 86 F). For F to C: subtract 32, then divide by 1.8.
