59 Fahrenheit to Rankine – Easy Conversion Explained

59 degrees Fahrenheit is equal to 518.67 degrees Rankine.

The Rankine scale is an absolute temperature scale like Kelvin, but uses Fahrenheit degree increments. To convert Fahrenheit to Rankine, you add 459.67 to the Fahrenheit temperature because Rankine starts at absolute zero, which is -459.67°F. So, 59°F plus 459.67 equals 518.67°R.

Conversion Formula

To convert Fahrenheit (°F) to Rankine (°R), you use the formula: °R = °F + 459.67.

This works because the Rankine scale starts at absolute zero, which is -459.67°F. Unlike Celsius and Kelvin, Rankine uses Fahrenheit degree intervals, so you add 459.67 instead of multiplying.

Example with 59°F:

• Start with 59°F
• Add 459.67 to 59: 59 + 459.67 = 518.67
• The result is 518.67°R

Conversion Example

• Convert 32°F to Rankine:
  • Take 32°F
  • Add 459.67: 32 + 459.67 = 491.67°R
• Convert 75°F to Rankine:
  • Start with 75°F
  • Add 459.67: 75 + 459.67 = 534.67°R
• Convert 0°F to Rankine:
  • 0 + 459.67 = 459.67°R
• Convert 100°F to Rankine:
  • 100 + 459.67 = 559.67°R
• Convert -20°F to Rankine:
  • -20 + 459.67 = 439.67°R

Conversion Definitions

Fahrenheit: Fahrenheit is a temperature scale where water freezes at 32 degrees and boils at 212 degrees under standard atmospheric pressure. It is commonly used in the United States for weather forecasts, cooking, and industrial temperature measurements. The scale divides the interval between freezing and boiling water into 180 degrees.

Rankine: Rankine is an absolute temperature scale based on Fahrenheit degrees, starting at absolute zero (-459.67°F). It is used mostly in thermodynamics and engineering, especially in the US. Unlike Celsius or Kelvin, Rankine increments match Fahrenheit rather than Celsius, making it convenient for calculations involving heat and energy.

Conversion FAQs

Can Rankine values be negative?

No, Rankine values cannot be negative because the scale starts at absolute zero, which is 0°R. Absolute zero is the lowest possible temperature where particles have minimal thermal motion, so all temperatures in Rankine are positive or zero.

Why add 459.67 and not multiply when converting Fahrenheit to Rankine?

Because Rankine uses the same size degree as Fahrenheit, only shifted to start at absolute zero. The difference between the scales is an offset of 459.67 degrees, so conversion requires addition, not multiplication. Multiplying would change the degree size, which is not desired.

Is Rankine used outside the United States?

Rankine is rarely used outside the United States. Most countries prefer Kelvin for absolute temperature measurements. Rankine remains common in American engineering and thermodynamic calculations because it aligns with Fahrenheit degrees.

How precise is the conversion from Fahrenheit to Rankine?

The conversion is exact when using the formula °R = °F + 459.67. The precision depends on how many decimal places you keep. Most practical uses round to two or four decimals, but the formula itself is mathematically precise.

Can I convert Rankine back to Fahrenheit?

Yes, to convert Rankine to Fahrenheit, you subtract 459.67 from the Rankine value. For example, 518.67°R minus 459.67 gives 59°F. This inverse operation works because the scales are offset by 459.67 degrees.
