Frequently Asked Questions (FAQ)
What is Celsius?
Celsius (or Centigrade) is the metric unit for temperature. Water freezes at 0°C and boils at 100°C.
What is Fahrenheit?
Fahrenheit is the temperature scale used in the United States. Water freezes at 32°F and boils at 212°F.
What is Kelvin?
Kelvin is the SI unit for temperature used in science. 0K is absolute zero, the theoretical point where all molecular motion stops.
How do I convert C to F?
Multiply by 9/5 (or 1.8) and add 32. Formula: (C × 1.8) + 32 = F.
