0 Fahrenheit to Rankine – Easy Conversion Explained

0 degrees Fahrenheit equals 459.67 degrees Rankine.

The Rankine scale starts at absolute zero like Kelvin but uses the Fahrenheit degree increment. So to convert Fahrenheit to Rankine, you add 459.67, which shifts the scale so absolute zero is zero Rankine.

Conversion Formula

To convert Fahrenheit (°F) to Rankine (°R), you add 459.67 to the Fahrenheit temperature. The formula is:

°R = °F + 459.67

This works because Rankine scale is absolute temperature scale used in engineering, where zero Rankine equals absolute zero. Fahrenheit degrees and Rankine degrees increments are equal, so adding 459.67 shifts the Fahrenheit value to Rankine scale.

Example:

• Convert 0°F to Rankine:
• °R = 0 + 459.67 = 459.67°R

Conversion Example

• Convert 32°F to Rankine:
  • Start with 32°F
  • Add 459.67: 32 + 459.67 = 491.67°R
  • Result is 491.67 Rankine
• Convert -40°F to Rankine:
  • Start with -40°F
  • Add 459.67: -40 + 459.67 = 419.67°R
  • Result is 419.67 Rankine
• Convert 100°F to Rankine:
  • Start with 100°F
  • Add 459.67: 100 + 459.67 = 559.67°R
  • Result is 559.67 Rankine
• Convert -10°F to Rankine:
  • Start with -10°F
  • Add 459.67: -10 + 459.67 = 449.67°R
  • Result is 449.67 Rankine

Conversion Definitions

Fahrenheit: Fahrenheit is a temperature scale where water freezes at 32 degrees and boils at 212 degrees under standard atmospheric pressure. It was created in the early 18th century and is mainly used in the United States for everyday temperature measurements. The scale divides the range between freezing and boiling into 180 equal parts called degrees.

Rankine: Rankine is an absolute temperature scale used in engineering that begins at absolute zero, equal to -459.67°F. It uses the same degree increments as the Fahrenheit scale but shifts zero to absolute zero temperature, making it useful when calculations require absolute temperature values in Fahrenheit units.

Conversion FAQs

Why is 0°F equal to 459.67°R and not zero?

Because Rankine scale starts at absolute zero, which corresponds to −459.67°F. Since Fahrenheit scale starts at a higher temperature, adding 459.67 shifts zero Fahrenheit to 459.67 Rankine. So zero Fahrenheit is far from absolute zero on the Rankine scale.

Can the conversion between Fahrenheit and Rankine involve multiplication or division?

No, the conversion only needs addition or subtraction of 459.67 because both scales use the same degree increments. The Rankine scale just shifts zero point to absolute zero, so no scaling factor is needed.

Is Rankine used outside of engineering fields?

Rankine is primarily used in thermodynamics and engineering fields that require absolute temperature measurements in Fahrenheit units. It’s rare outside those areas, with Kelvin preferred in scientific contexts involving Celsius units.

What happens if I input a negative Fahrenheit value in the conversion tool?

The tool adds 459.67 to the negative Fahrenheit value, resulting in a Rankine value that’s still positive, since absolute zero is zero Rankine. Negative Fahrenheit temperatures correspond to Rankine values above zero.

Does converting from Rankine to Fahrenheit just subtract 459.67?

Yes, to convert Rankine to Fahrenheit, you subtract 459.67. This reverses the shift done in the Fahrenheit to Rankine conversion, bringing absolute zero back to -459.67°F.
