Temperature Converter

About Temperature Conversion

Temperature conversion is essential for scientific calculations, cooking, weather forecasting, and international communication. Our temperature converter supports the three most commonly used temperature scales: Celsius, Fahrenheit, and Kelvin.

Temperature Scales

Celsius (°C)

Based on water's freezing point (0°C) and boiling point (100°C) at standard atmospheric pressure. Widely used worldwide for everyday temperature measurements.

Fahrenheit (°F)

Commonly used in the United States. Water freezes at 32°F and boils at 212°F. Named after physicist Daniel Gabriel Fahrenheit.

Kelvin (K)

The SI base unit of temperature. Absolute zero is 0K (-273.15°C). Used primarily in scientific and engineering applications.

Conversion Formulas

Celsius ↔ Fahrenheit

°F = (°C × 9/5) + 32

°C = (°F - 32) × 5/9

Celsius ↔ Kelvin

K = °C + 273.15

°C = K - 273.15

Fahrenheit ↔ Kelvin

K = (°F - 32) × 5/9 + 273.15

°F = (K - 273.15) × 9/5 + 32

Common Temperature References

Reference Point	Celsius	Fahrenheit	Kelvin
Absolute Zero	-273.15°C	-459.67°F	0K
Water Freezes	0°C	32°F	273.15K
Room Temperature	20°C	68°F	293.15K
Body Temperature	37°C	98.6°F	310.15K
Water Boils	100°C	212°F	373.15K

Common Applications

• Weather & Climate: Converting between local and international weather reports
• Cooking & Baking: Converting oven temperatures for international recipes
• Science & Engineering: Laboratory calculations and industrial processes
• Medical: Body temperature monitoring and medical equipment calibration
• HVAC: Heating, ventilation, and air conditioning system settings

Tips for Accurate Conversion

• Remember that Kelvin never uses the degree symbol (°)
• Absolute zero (-273.15°C) is the lowest possible temperature
• For quick Celsius to Fahrenheit: multiply by 2 and add 30 (approximate)
• For scientific calculations, always use the exact conversion formulas
• Consider significant figures when reporting converted temperatures
