Temperature Converter

Temperature conversion uses mathematical formulas to translate measurements between three primary scales: Celsius (°C), Fahrenheit (°F), and Kelvin (K). The Celsius scale sets water's freezing point at 0°C and boiling point at 100°C. Fahrenheit uses 32°F for freezing and 212°F for boiling, with 180 degrees between them. Kelvin is the absolute thermodynamic temperature scale starting at absolute zero (0 K = -273.15°C), used primarily in scientific contexts. To convert Celsius to Fahrenheit: °F = (°C × 9/5) + 32. To convert Fahrenheit to Celsius: °C = (°F - 32) × 5/9. To convert Celsius to Kelvin: K = °C + 273.15. Our converter performs these calculations instantly with high precision, handling all conversion combinations bidirectionally.

1. International Travel & Communication
Convert weather forecasts and temperature readings when traveling between countries using different temperature scales. Americans traveling to Europe need Fahrenheit to Celsius conversion, while international visitors to the US need the reverse.

2. Cooking & Baking
Convert oven temperatures between Celsius and Fahrenheit when following international recipes. British recipes use Celsius/Gas Mark, American recipes use Fahrenheit, and proper conversion ensures baking success and food safety.

3. Scientific Research & Education
Convert between Celsius, Fahrenheit, and Kelvin for physics, chemistry, and engineering applications. Scientific formulas often require Kelvin (absolute temperature), while experimental data may be recorded in Celsius or Fahrenheit.

4. HVAC & Climate Control
Set thermostats and configure climate control systems when dealing with equipment from different regions. Smart home devices may display different units than building management systems.

5. Health & Medical Applications
Convert body temperature readings between scales for medical records, international consultations, or when using thermometers with different unit displays. Normal body temperature is 37°C or 98.6°F.

• Remember key reference points: water freezes at 0°C/32°F, boils at 100°C/212°F

• Room temperature is approximately 20-22°C (68-72°F)

• Body temperature is 37°C (98.6°F) - use this to calibrate your sense of temperature scales

• Kelvin is never negative - absolute zero (0 K) is the coldest possible temperature

• When baking, round oven temperatures to the nearest 5-10 degrees for practical use

• A 1°C change equals a 1.8°F change - Fahrenheit is more granular

• For quick mental estimation: °C to °F ≈ double and add 30 (accurate within a few degrees)
