Yes, TempConvert uses standard mathematical formulas for temperature conversion and rounds results to 2 decimal places for precision. The formulas are based on the official conversion standards.

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

To convert Fahrenheit to Celsius, subtract 32 from the Fahrenheit temperature and multiply by 5/9. Formula: °C = (°F - 32) × 5/9. For example, 68°F = (68 - 32) × 5/9 = 20°C.

To convert Celsius to Kelvin, add 273.15. To convert Kelvin to Celsius, subtract 273.15. Kelvin is an absolute temperature scale used primarily in scientific contexts.

Celsius (°C) is a metric scale where water freezes at 0°C and boils at 100°C at standard atmospheric pressure. Fahrenheit (°F) is primarily used in the United States, where water freezes at 32°F and boils at 212°F. Celsius uses a 0-100 scale between freezing and boiling, while Fahrenheit uses 32-212.

Different temperature scales developed in different regions and for different purposes. Celsius is the metric standard used worldwide. Fahrenheit is still used in the US due to historical adoption. Kelvin is used in science because it starts at absolute zero, the coldest possible temperature.

TempConvert supports three temperature scales: Celsius (°C), Fahrenheit (°F), and Kelvin (K). You can convert between any combination of these scales instantly.

Yes! Press Escape to clear values, Enter to swap conversion direction (where available), Ctrl+C to copy the result, and Ctrl+P to print. The converter also auto-focuses on page load for instant typing.
