Frequently Asked Questions

How do I convert Celsius to Fahrenheit?
Multiply the Celsius value by 9/5 (or 1.8) and add 32. For example, 100°C × 1.8 + 32 = 212°F.
What is absolute zero?
Absolute zero is the lowest possible temperature: 0 Kelvin, −273.15°C, or −459.67°F. At this point, molecular motion theoretically stops.
When should I use Kelvin?
Kelvin is the SI unit for temperature used in scientific contexts. It starts at absolute zero and uses the same increment size as Celsius.
What is normal human body temperature in Fahrenheit?
Normal body temperature is approximately 98.6°F (37°C or 310.15 K), though it can vary slightly from person to person.
