Temperature Converter

About This Tool

This Temperature Converter provides precise conversions between the most commonly used temperature scales: Celsius, Fahrenheit, Kelvin, and Rankine. Unlike conversions for length or mass which rely on simple multiplication, temperature scales have different zero points and interval sizes, requiring specific formulas for accurate conversion.

The base reference for our calculations is Celsius (°C), the standard for the metric system. Whether you are a student, a scientist working with absolute temperatures, or simply trying to convert a recipe's instructions, this tool handles the unique mathematical relationships between the scales for you.

Tips & Features

• Understanding the Scales: Celsius and Fahrenheit are common for everyday use, while Kelvin and Rankine are absolute scales (where 0 is absolute zero) and are standard in scientific and engineering contexts.
• It's Not Just Multiplication: Temperature conversion formulas involve addition and subtraction as well as multiplication (e.g., °F = °C × 9/5 + 32). This is because the zero points on different scales do not align.
• Kelvin and Celsius: The size of one degree is the same for both Kelvin and Celsius. This means a temperature change of 1 K is identical to a change of 1 °C. The only difference is their starting point (0 K = -273.15 °C).
