Multiply the Kelvin value by 9/5 (or 1.8). For example, 293.15 K × 9/5 = 527.67 °R.
A Rankine degree is 5/9 the size of a Kelvin degree (same as Fahrenheit vs Celsius). To convert from the larger unit (Kelvin) to the smaller unit (Rankine), multiply by 9/5.
Yes. Both Kelvin and Rankine are absolute scales, so their zero points are the same: absolute zero, the theoretical minimum temperature.
Water boils at 373.15 K and 671.67 °R at standard atmospheric pressure.
The triple point of water (273.16 K) equals 491.688 °R.
