About Fahrenheit and Celsius

Detailed information about both units of measurement.

IMPERIAL UNIT

Fahrenheit

°F
Definition
The imperial temperature scale where water freezes at 32° and boils at 212° at standard atmospheric pressure.
SI / Standard Information
Developed by Daniel Gabriel Fahrenheit in 1724. Uses a scale where 0°F was the freezing point of brine and 96°F was body temperature.
Approximate Comparison
1°F is about 0.56°C. A comfortable room is around 70°F.
Practical Applications
  • US weather forecasting
  • US cooking and oven temperatures
  • HVAC thermostat settings
  • US medical temperature measurement
Real-World Examples
  • A comfortable room temperature is 68-72°F
  • Human body temperature is 98.6°F
  • Water freezes at 32°F and boils at 212°F
METRIC UNIT

Celsius

°C
Definition
The metric temperature scale where water freezes at 0° and boils at 100° at standard atmospheric pressure.
SI / Standard Information
SI-derived unit (°C). Named after Anders Celsius. The kelvin scale uses the same interval but starts at absolute zero.
Approximate Comparison
1°C is about 1.8°F. A comfortable room is around 21°C.
Practical Applications
  • Worldwide weather reporting
  • Medical thermometers
  • Cooking and baking
  • Scientific laboratory measurements
Real-World Examples
  • Room temperature is typically 20-22°C
  • Human body temperature is 37°C
  • Water freezes at 0°C and boils at 100°C
