Frequently Asked Questions
What is the formula to convert Celsius to Fahrenheit?
°F = (°C × 9/5) + 32. For example, 100°C = (100 × 9/5) + 32 = 212°F. A quick estimate: double the Celsius and add 30.
What is absolute zero?
Absolute zero is 0 Kelvin = -273.15°C = -459.67°F. It is the theoretical lowest temperature where all molecular motion stops. It has never been fully achieved in practice.
What is normal body temperature?
Normal body temperature is approximately 37°C (98.6°F). However, it can vary between 36.1°C (97°F) and 37.2°C (99°F) and is usually lower in the morning and higher in the evening.
What temperature is water's boiling point?
Water boils at 100°C (212°F) at standard atmospheric pressure (sea level). At higher altitudes, water boils at lower temperatures due to reduced air pressure.
Why do some countries use Fahrenheit?
The US, Bahamas, Palau, and some other territories use Fahrenheit. Most other countries switched to Celsius (part of the metric system) in the 20th century.
