Quick Reference

Water freezing point: 0°C = 32°F = 273.15K
Water boiling point: 100°C = 212°F = 373.15K
Human body temperature: 37°C = 98.6°F = 310.15K
Absolute zero: -273.15°C = -459.67°F = 0K
Room temperature: 20°C = 68°F = 293.15K
Celsius = Fahrenheit: -40°C = -40°F

📐 Formula

°F = °C × 9/5 + 32, K = °C + 273.15

💡 How It Works

  • •Celsius (°C) sets water's freezing point at 0° and boiling point at 100°. It's used in most countries for everyday purposes.
  • •Fahrenheit (°F) is primarily used in the United States. Water freezes at 32°F and boils at 212°F.
  • •Kelvin (K) is the SI unit for temperature in science. It starts at absolute zero (0K = -273.15°C).
  • •Celsius and Fahrenheit are equal at -40: -40°C = -40°F
  • •Celsius to Fahrenheit: °F = °C × 1.8 + 32 (or °C × 9/5 + 32)
  • •Fahrenheit to Celsius: °C = (°F - 32) × 5/9

❓ FAQ

Q. What's the difference between Celsius and Fahrenheit?

A. Celsius uses water's freezing (0°C) and boiling points (100°C), while Fahrenheit uses 32°F and 212°F. Most countries use Celsius; the US primarily uses Fahrenheit.

Q. When is Kelvin used?

A. Kelvin is used in science, especially physics and chemistry. It's convenient for thermodynamic calculations as it has no negative values.

Q. What is absolute zero?

A. The lowest theoretically possible temperature: 0K = -273.15°C = -459.67°F. At this temperature, molecular motion would completely stop.

Q. What is 37°C in Fahrenheit?

A. 37°C = 98.6°F. This is normal human body temperature. In the US, body temperature is typically measured in Fahrenheit.

Q. What is 350°F in Celsius?

A. 350°F ≈ 177°C. This is a very common baking temperature in American recipes.
