FAQ
Frequently asked questions
Why isn't temperature converted like length or weight?
Temperature scales don't share a common zero point, so each conversion needs its own formula rather than a simple multiplier.
What is absolute zero in each scale?
0 K, which equals -273.15°C and -459.67°F.
Can I enter negative temperatures?
Yes, except Kelvin cannot go below 0 (absolute zero).
Which scale is used in science?
Kelvin is the standard SI unit for scientific temperature measurement.
