Temperature Converter

Our Temperature Converter is a versatile tool that allows you to convert temperatures between the three most commonly used temperature scales: Celsius (°C), Fahrenheit (°F), and Kelvin (K). Whether you’re working on scientific calculations, following international recipes, or just trying to understand weather forecasts from different countries, this converter makes temperature conversion quick and accurate.

Understanding Temperature Scales

Celsius (°C)

The Celsius scale, also known as centigrade, is used in most countries worldwide. It’s based on water’s freezing point (0°C) and boiling point (100°C) at standard atmospheric pressure. This scale is widely used in everyday life, scientific work, and meteorology.

Fahrenheit (°F)

The Fahrenheit scale is primarily used in the United States. On this scale, water freezes at 32°F and boils at 212°F at standard atmospheric pressure. While less common globally, it’s still important for international communication and understanding.

Kelvin (K)

The Kelvin scale is the SI unit of temperature and is used primarily in scientific contexts. It starts at absolute zero (0K = -273.15°C), the theoretical lowest possible temperature. Unlike Celsius and Fahrenheit, Kelvin doesn’t use the degree symbol (°).

Conversion Formulas

Here are the formulas used for converting between different temperature scales:

Celsius to Fahrenheit

$°F = (°C × \frac{9}{5}) + 32$

Fahrenheit to Celsius

$°C = (°F - 32) × \frac{5}{9}$

Celsius to Kelvin

$K = °C + 273.15$

Kelvin to Celsius

$°C = K - 273.15$

Fahrenheit to Kelvin

$K = (°F - 32) × \frac{5}{9} + 273.15$

Kelvin to Fahrenheit

$°F = (K - 273.15) × \frac{9}{5} + 32$

Common Temperature References

Here are some common temperature references to help you understand the scales:

• Water freezing point: 0°C = 32°F = 273.15K
• Room temperature: ~20°C = ~68°F = ~293.15K
• Body temperature: 37°C = 98.6°F = 310.15K
• Water boiling point: 100°C = 212°F = 373.15K

How to Use the Calculator

1. Enter a temperature value in any of the three input fields (Celsius, Fahrenheit, or Kelvin)
2. The calculator will automatically convert and display the equivalent temperatures in the other two scales
3. Use the Reset button to clear all fields and start a new conversion
4. Hover over the input fields for helpful tooltips

Applications

Temperature conversion is useful in many fields:

• Cooking: Converting recipe temperatures between °F and °C
• Science: Laboratory work often requires converting between K and °C
• Weather: Understanding international weather forecasts
• Industry: Manufacturing processes often specify temperatures in different scales
• Healthcare: Converting between body temperature measurements

Tips for Accurate Conversion

• Always use decimal points for precise measurements
• Remember that Kelvin doesn’t use the degree symbol (°)
• For scientific calculations, use Kelvin when specified
• Double-check your conversions for critical applications

Technical Notes

This calculator provides conversions accurate to two decimal places, which is sufficient for most practical purposes. For extremely precise scientific work, please consult specialized scientific instruments or conversion tools.
