  3. 3

    Add 273.15 to the Celsius result to get Kelvin.

  4. 4

    The result is displayed in Kelvin.

reaumur * 1.25 + 273.15

常见问题

What is the Réaumur scale?

The Réaumur scale sets the freezing point of water at 0°Ré and the boiling point at 80°Ré. It was used in Europe in the 18th and 19th centuries.

How do I convert Kelvin to Réaumur?

Use the inverse formula: °Ré = (K - 273.15) / 1.25.

Why is the conversion factor 1.25?

Because 80°Ré equals 100°C, so 1°Ré = 100/80 = 1.25°C.

公式

此计算器背后的数学公式，供您核对结果。

Réaumur to Kelvin

K = °Ré × 1.25 + 273.15

First convert Réaumur to Celsius by multiplying by 1.25, then add 273.15 to get Kelvin.

Example:

Input: °Ré = 20

Calculation: 20 × 1.25 + 273.15 = 25 + 273.15

Result: 298.15 K

实际应用场景

此计算在日常生活中的应用。

Historical temperature records

Convert old scientific data recorded in Réaumur to modern Kelvin units.

Example: A 19th-century lab notebook lists 30°Ré.

Education and science

Help students understand temperature scales and conversions.

Example: Teaching the relationship between Celsius and Réaumur.

Culinary heritage

Some traditional European recipes use Réaumur for oven temperatures.

Example: A recipe calls for 40°Ré.

Tips

  • Remember that 0°Ré is the freezing point of water, so 0°Ré = 273.15 K.
  • For quick mental estimates, multiply °Ré by 1.25 and add 273.
  • Use the calculator for negative values too; absolute zero is -218.52°Ré.

Common Mistakes to Avoid

  • Forgetting to add 273.15 after converting to Celsius.
  • Using 1.8 instead of 1.25 as the conversion factor (that's for Fahrenheit).
  • Confusing Réaumur with Rankine or other scales.

假设与限制

  • Use the stated inputs and units.
  • Results are estimates for planning and education.
  • Check measurements and source data before making an important decision.
