💡 Quick Tips
Celsius (°C): Used in most countries worldwide. Water freezes at 0°C and boils at 100°C.
Fahrenheit (°F): Used in the USA. Water freezes at 32°F and boils at 212°F.
Kelvin (K): Scientific scale starting at absolute zero. No degree symbol. Water freezes at 273.15K.
❓ Frequently Asked Questions
Q: What's the difference between Celsius and Fahrenheit?
A: Celsius and Fahrenheit are two different temperature scales. Celsius is used by most countries and is based on water freezing at 0° and boiling at 100°. Fahrenheit, used mainly in the USA, has water freezing at 32° and boiling at 212°.
Q: What is Kelvin and when is it used?
A: Kelvin is the SI unit of temperature used in science. It starts at absolute zero (the coldest possible temperature) and uses the same degree size as Celsius. It's used in physics, chemistry, and astronomy. Note: Kelvin doesn't use the degree symbol (°).
Q: How do I convert Fahrenheit to Celsius quickly?
A: Use this formula: Subtract 32, then multiply by 5/9. For example: 68°F = (68-32) × 5/9 = 20°C. Or use our calculator for instant results!
Q: Why is 0 Kelvin called absolute zero?
A: Absolute zero (0 Kelvin or -273.15°C) is the lowest possible temperature where all molecular motion stops. Nothing can be colder than absolute zero - it's a fundamental limit in physics.
Q: Is this converter accurate enough for scientific work?
A: Yes! Our converter uses the standard conversion formulas and displays results to 2 decimal places, which is sufficient for most scientific and engineering applications. For extremely precise work requiring more decimals, the formulas are provided for manual calculation.
Q: Can I use negative temperatures?
A: Absolutely! You can enter any temperature value, positive or negative. Note that Kelvin doesn't go below 0 (absolute zero), so if you enter a very low Celsius or Fahrenheit value, the Kelvin result will show 0 as the minimum.
