- What temperature units can I convert between?
- You can convert between Celsius (°C), Fahrenheit (��F), and Kelvin (K). These cover all commonly used temperature scales in scientific and everyday use.
- How do the temperature scales differ?
- Celsius: Water freezes at 0°C and boils at 100°C. Fahrenheit: Water freezes at 32°F and boils at 212°F. Kelvin: Absolute zero is 0K (-273.15°C). Kelvin is used in scientific calculations.
- Which countries use which scales?
- Most countries use Celsius. The United States primarily uses Fahrenheit. Scientists worldwide use Kelvin for calculations and Celsius for measurements.
- What's special about the Kelvin scale?
- Kelvin is an absolute temperature scale, starting at absolute zero (0K = -273.15°C), the lowest possible temperature. It's crucial in scientific calculations and doesn't use degrees (just K).
- How accurate are the conversions?
- Our conversions use precise formulas: °F = (°C × 9/5) + 32 and K = °C + 273.15. Results are rounded to 2 decimal places for practical use.
- Why do some temperatures have negative values?
- Celsius and Fahrenheit can be negative (below freezing point of water). Kelvin never has negative values as it starts at absolute zero. Common example: -40°C equals -40°F.
- What are some common reference temperatures?
- Water freezes: 0°C = 32°F = 273.15K. Room temperature: ~20°C = ~68°F = ~293.15K. Body temperature: 37°C = 98.6°F = 310.15K. Water boils: 100°C = 212°F = 373.15K.
