How do I convert Celsius to Fahrenheit?
Multiply °C by 9/5 (or 1.8), then add 32. Formula: °F = (°C × 1.8) + 32. Example: 25°C = 77°F.
How do I convert Fahrenheit to Celsius?
Subtract 32, then multiply by 5/9. Formula: °C = (°F - 32) × 5/9. Example: 98.6°F = 37°C.
What is 0°C in Fahrenheit?
0°C = 32°F (freezing point of water). 100°C = 212°F (boiling point). Body temperature is 37°C = 98.6°F.
What is Kelvin and when is it used?
Kelvin is the SI unit for absolute temperature. 0K = -273.15°C (absolute zero). Used in science and engineering.
What temperature is the same in Celsius and Fahrenheit?
-40 degrees is the same in both scales. -40°C = -40°F. This is the only point where they intersect.
How do I convert Kelvin to Celsius?
Subtract 273.15. Example: 300K = 26.85°C. For Celsius to Kelvin, add 273.15.
What is room temperature in Celsius and Fahrenheit?
Room temperature is typically 20-22°C = 68-72°F.
What is the boiling point of water?
Water boils at 100°C = 212°F = 373.15K at sea level. Lower altitude = lower boiling point.
