About Celsius and Rankine

Detailed information about both units of measurement.

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
SCIENTIFIC UNIT

Rankine

°R
Definition
The absolute Fahrenheit scale. Zero Rankine is absolute zero. Used primarily in US engineering fields.
SI / Standard Information
Named after William John Macquorn Rankine. One Rankine degree equals one Fahrenheit degree. 0°R = -459.67°F = 0 K.
Approximate Comparison
A change of 1°R is exactly the same as a change of 1°F.
Practical Applications
  • US aerospace engineering
  • Thermodynamic calculations
  • Some HVAC engineering
  • US academic engineering curricula
Real-World Examples
  • Room temperature is about 527°R
  • Water freezes at 491.67°R
  • Water boils at 671.67°R
