Question 1

How do I convert Celsius to Fahrenheit?

Accepted Answer

Multiply the Celsius temperature by 9/5 (or 1.8) and add 32. Formula: °F = (°C × 9/5) + 32. For example, 20°C = (20 × 1.8) + 32 = 68°F.

Question 2

What is absolute zero in different scales?

Accepted Answer

Absolute zero is -273.15°C, -459.67°F, and 0 K. It is the lowest possible temperature where all molecular motion stops.

Question 3

What is the normal human body temperature?

Accepted Answer

Normal human body temperature is approximately 37°C (98.6°F or 310.15 K). It can vary slightly from person to person and throughout the day.

Question 4

How do I convert Kelvin to Celsius?

Accepted Answer

Subtract 273.15 from the Kelvin temperature. Formula: °C = K - 273.15. For example, 300 K = 300 - 273.15 = 26.85°C.

Question 5

Why does the US use Fahrenheit?

Accepted Answer

The US uses Fahrenheit due to historical reasons — it was the standard when the US measurement system was established. The Fahrenheit scale was proposed by Daniel Fahrenheit in 1724. Most other countries adopted Celsius during metrication.

Question 6

What temperature does water boil at?

Accepted Answer

At standard atmospheric pressure (1 atm), water boils at 100°C (212°F or 373.15 K). At higher altitudes, the boiling point decreases due to lower atmospheric pressure.

Question 7

What is the Kelvin scale used for?

Accepted Answer

Kelvin is the SI base unit of temperature, used primarily in science and engineering. It starts at absolute zero (0 K) and has no negative values. It's essential in thermodynamics, physics, and astronomy.

Question 8

Is this converter accurate?

Accepted Answer

Yes, the converter uses precise formulas with full floating-point precision. Results are displayed with 4 decimal places for scientific accuracy while remaining practical for everyday use.
