0 Fahrenheit to Rankine – Full Calculation Guide

0 degrees Fahrenheit equals 459.67 degrees Rankine.

The Rankine scale starts at absolute zero, just like Kelvin, but uses the Fahrenheit degree size. To convert Fahrenheit to Rankine, you add 459.67 because absolute zero is -459.67°F, so 0°F plus 459.67 gives the Rankine value.

Conversion Formula

To convert Fahrenheit to Rankine, the formula is:

Rankine (°R) = Fahrenheit (°F) + 459.67

Because Rankine starts at absolute zero, which is -459.67°F, you add 459.67 to any Fahrenheit temperature to find its Rankine equivalent.

Example:

• Start temperature: 0°F
• Add 459.67 to it: 0 + 459.67 = 459.67°R
• So, 0°F equals 459.67 Rankine exactly.

Conversion Example

• Convert 32°F to Rankine:
  • Take 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
  • Answer is 419.67 Rankine
• Convert 100°F to Rankine:
  • Take 100°F
  • Add 459.67 → 100 + 459.67 = 559.67°R
  • So, 100°F equals 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
• Convert 212°F to Rankine:
  • Start at 212°F
  • Add 459.67 → 212 + 459.67 = 671.67°R
  • Answer: 671.67 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 uses degrees Fahrenheit (°F) as units and is primarily used in the United States for weather forecasts, cooking, and industry.

Rankine: Rankine is an absolute temperature scale used in engineering fields, especially thermodynamics, where zero Rankine represents absolute zero. It uses increments equal to Fahrenheit degrees but starts at -459.67°F, making it useful for temperature calculations involving gas laws.

Conversion FAQs

Why is 459.67 added to Fahrenheit to get Rankine?

Because Rankine scale starts at absolute zero, which is -459.67°F, all Fahrenheit temperatures must be shifted by adding 459.67 to align them with the Rankine scale. The size of one degree Rankine equals one degree Fahrenheit, so only the offset changes.

Can Rankine temperatures be negative?

No, Rankine temperatures can’t be negative since the scale starts at absolute zero (0 °R). Absolute zero is the lowest limit, so all Rankine values are positive or zero, unlike Fahrenheit which has negative values.

Is Rankine used outside of engineering?

Rankine scale is mostly found in engineering and thermodynamics in the US, particularly in heat and energy calculations. It’s rarely used in general weather or daily life, where Fahrenheit or Celsius are preferred.

How precise is the conversion from Fahrenheit to Rankine?

The conversion is exact because both scales use the same degree size, only offset differs. Adding 459.67 gives a direct and precise conversion every time without rounding errors in theory.

What happens if I forget to add 459.67 in conversion?

Without adding 459.67, the temperature will be off by a large margin (absolute zero offset). For example, 0°F would appear as 0°R, which is physically incorrect. This mistake leads to wrong temperature values in thermodynamic calculations.
