Converting temperatures from Kelvin to Rankine is straightforward: simply multiply the Kelvin temperature by 1.8. This is because both scales start at absolute zero, but while the Kelvin scale uses the Celsius degree increment, the Rankine scale uses the Fahrenheit degree increment. For example, to convert 300 Kelvin to Rankine, calculate 300 × 1.8, resulting in 540°R. This conversion is particularly useful in thermodynamic calculations where absolute temperature measurements are required.
