80 Fahrenheit to Rankine – Easy Conversion Explained

80 degrees Fahrenheit is equal to 480 degrees Rankine. Since Rankine is an absolute temperature scale based on Fahrenheit degrees, converting involves adding 459.67 to the Fahrenheit temperature.

Fahrenheit and Rankine are temperature scales where Fahrenheit measures temperature with its own units, while Rankine is an absolute scale similar to Kelvin but based on Fahrenheit increments. To convert Fahrenheit to Rankine, you simply add 459.67 because Rankine starts at absolute zero, which is -459.67°F, and each degree Rankine equals one Fahrenheit degree.

Conversion Tool

Conversion Formula

The conversion from fahrenheit to rankine involves adding 459.67 to the Fahrenheit temperature. This is because Rankine starts at absolute zero, which is -459.67°F. The formula is: Rankine = Fahrenheit + 459.67. For example, converting 80°F: 80 + 459.67 = 539.67°R.

This works because the Rankine scale is directly proportional to Fahrenheit, with the zero point at absolute zero. The addition aligns the Fahrenheit temperature with the absolute scale used in Rankine, ensuring an accurate conversion from a relative to an absolute measure.
