Celsius (°C) is used worldwide for most temperature measurements. Fahrenheit (°F) is primarily used in the United States. Kelvin (K) is the SI unit for thermodynamic temperature. Rankine (°R) is the Fahrenheit equivalent of Kelvin. Each scale has different zero points and degree intervals.
Kelvin is an absolute scale because it starts at absolute zero (-273.15°C), the theoretical point where molecular motion stops. Unlike Celsius and Fahrenheit, Kelvin has no negative values, making it ideal for scientific calculations involving gas laws and thermodynamics.
For a quick mental approximation: Double the Celsius, subtract 10%, then add 32. For example, 20°C: double is 40, minus 10% (4) is 36, plus 32 is 68°F (actual: 68°F). For precise conversions, use our calculator with the exact formula: (°C × 9/5) + 32.
Rankine scale is primarily used in engineering fields in the United States, particularly in thermodynamics and mechanical engineering. It's the Fahrenheit equivalent of Kelvin - an absolute temperature scale where 0°R is absolute zero, but using Fahrenheit degree increments instead of Celsius.
