Temperature Converter

Understanding Temperature Scales

Unlike length or weight, temperature scales do not always share an absolute zero point. This means you cannot simply multiply to convert between them; you often must add or subtract as well.

The Three Primary Scales

• Celsius (°C): Used by most of the world. It is based on the freezing point (0°C) and boiling point (100°C) of water at standard atmospheric pressure.
• Fahrenheit (°F): Used primarily in the United States. Water freezes at 32°F and boils at 212°F.
• Kelvin (K): The primary unit of temperature in the physical sciences. It is an absolute scale where 0 K (absolute zero) is the point at which all thermal motion ceases.

Key Conversion Formulas

• Fahrenheit to Celsius: °C = (°F - 32) × 5/9
• Celsius to Fahrenheit: °F = (°C × 9/5) + 32
• Celsius to Kelvin: K = °C + 273.15

How Our Tool Works

The Temperature Converter provides real-time, bi-directional conversion. As soon as you type a number in the "From" input, the result instantly appears in the "To" field. You can easily reverse the conversion direction by clicking the Swap icon in the center. We also automatically generate a quick reference table based on your selected units to help you memorize common conversions.
