Temperature

To Obtain
  Celsius, °C Fahrenheit, °F Kelvin, K Rankine, R
Use formula
Celsius, °C - °F = (°C x 1.8) + 32 K = °C +273.16 R = (°C +273.16)x 1.8
Fahrenheit, °F °C = (°F - 32)/1.8 - K = ((°F-32)/1.8)+273.16 R = °F + 459.69
Kelvin, K °C = K - 273.16 °F = (( K - 273.16) x 1.8) +32 - R = K x 1.8
Rankine, R °C = (R/1.8) - 273.16 °F = R - 459.69 K = R/1.8 -
