Frequently Asked Questions
How do I convert between Celsius and Fahrenheit?
Celsius to Fahrenheit: multiply by 9/5 (or 1.8) and add 32. Fahrenheit to Celsius: subtract 32 and multiply by 5/9. Key points: 0C = 32F, 100C = 212F, 37C = 98.6F.
What is the Kelvin scale?
Kelvin is the SI unit for temperature. It starts at absolute zero (-273.15 Celsius). To convert: Kelvin = Celsius + 273.15. Water freezes at 273.15 K and boils at 373.15 K.
What is the Temperature Converter?
The temperature converter converts between Celsius, Fahrenheit and Kelvin.
How does the Temperature Converter work?
Enter the temperature and source unit. The calculator converts to the other two units. Formulas: F = C * 9/5 + 32. K = C + 273.15.
Key Data and Facts
Freezing point of water: 0 C = 32 F = 273.15 K. Boiling point: 100 C = 212 F = 373.15 K. Body temperature: 37 C = 98.6 F. Absolute zero: -273.15 C = 0 K.
Step-by-Step Guide
How to use den Temperatur-Umrechner step by step: 1. Ausgangseinheit choose -- Celsius (Grad C), Fahrenheit (Grad F) oder Kelvin (K). 2. Wert enter -- der Rechner konvertiert sofort in die beiden anderen Einheiten. 3. Formeln: Celsius zu Fahrenheit: Grad F = Grad C * 9/5 + 32. Fahrenheit zu Celsius: Grad C = (Grad F - 32) * 5/9. Celsius zu Kelvin: K = Grad C + 273,15. 4. Wichtige Referenzpunkte: Gefrierpunkt Wasser = 0 Grad C = 32 Grad F = 273,15 K. Siedepunkt Wasser = 100 Grad C = 212 Grad F. Koerpertemperatur = 37 Grad C = 98,6 Grad F. 5. Der Schnittpunkt: -40 Grad C = -40 Grad F (beide Skalen treffen sich). 6. Haeufige Anwendungen: Wetterberichte aus den USA umrechnen (z. B. 77 Grad F = 25 Grad C), Backrezepte anpassen (350 Grad F = 177 Grad C), Fiebermessung (ab 38 Grad C = 100,4 Grad F gilt als Fieber). Tipp: Schnelle Schaetzung Grad F zu Grad C: (Grad F - 30) / 2.
Calculation Example
72 Grad F in Celsius: (72 - 32) * 5/9 = 22,2 Grad C. 37 Grad C in Fahrenheit: 37 * 9/5 + 32 = 98,6 Grad F.
