温度转换器
在浏览器中处理或呈现温度转换。
使用步骤
如何使用
- Enter a temperature and choose its input unit.
- Select Convert temperature to calculate all three scales.
- Review the converted values and copy the result if needed.
Three common temperature scales
Celsius and Fahrenheit use offset scales, while Kelvin starts at absolute zero and uses the same degree size as Celsius. The converter displays all three values so you can compare them at a glance.
Absolute zero validation
Temperatures below absolute zero are rejected: −273.15 °C, −459.67 °F, and 0 K. This keeps results physically meaningful and catches accidental unit or sign errors.
Private browser conversion
Parsing, validation, and conversion happen locally in your browser. No temperature value is uploaded or stored by this page.
常见问题
你可能还想知道
What is the formula from Celsius to Fahrenheit?
Multiply Celsius by 9/5, then add 32: °F = (°C × 9/5) + 32.
Can Kelvin be negative?
No. Kelvin begins at absolute zero, so values below 0 K are invalid.
How many decimal places are shown?
The converter keeps the calculation in full JavaScript number precision and formats each result to up to 10 significant digits for readability.
Does the converter upload my value?
No. The conversion runs entirely in your browser.
