Understanding Temperature Units

Celsius (°C)

The Celsius scale is based on water's freezing point (0°C) and boiling point (100°C) at standard atmospheric pressure. It's the most commonly used temperature scale in scientific and engineering applications worldwide.

Fahrenheit (°F)

The Fahrenheit scale sets water's freezing point at 32°F and boiling point at 212°F. It's primarily used in the United States and a few other countries for non-scientific applications.

Kelvin (K)

The Kelvin scale is the SI base unit of temperature. It starts at absolute zero (-273.15°C) and uses the same increment size as Celsius. It's commonly used in scientific calculations and thermal physics.

Common Temperature Conversions

Medical

  • Normal body temperature: 37°C = 98.6°F
  • Mild fever: 38°C = 100.4°F
  • High fever: 39°C = 102.2°F
  • Medical grade: 35-42°C = 95-107.6°F

Cooking

  • Air fryer: 200°C = 392°F
  • Oven preheat: 350°F = 175°C
  • Deep frying: 190°C = 374°F
  • Warming: 170°F = 77°C

Home & Office

  • Room temperature: 20-25°C = 68-77°F
  • AC setting: 72°F = 22.2°C
  • Winter heating: 68°F = 20°C
  • Hot water: 49°C = 120°F
