671.67 - (delisle * 6 / 5)常见问题
What is the Delisle scale?
The Delisle scale (°De) is an obsolete temperature scale where water boils at 0 degrees and freezes at 150 degrees. It decreases as temperature increases.
What is the Rankine scale?
The Rankine scale (°R) is an absolute temperature scale used in engineering, with zero at absolute zero. The freezing point of water is 491.67 °R and the boiling point is 671.67 °R.
How do I convert Delisle to Rankine manually?
Use the formula: °R = 671.67 - (°De × 6/5). For example, 100 °De equals 551.67 °R.

公式
此计算器背后的数学公式，供您核对结果。
Delisle to Rankine
This formula converts a temperature from the Delisle scale to the Rankine scale by relating the two scales to the Celsius scale.
Example:
Input: °De = 100
Calculation: 671.67 - (100 × 6/5) = 671.67 - 120 = 551.67
Result: 551.67 °R
实际应用场景
此计算在日常生活中的应用。
Historical temperature records
Convert old temperature readings recorded in Delisle to modern Rankine for comparison.
Example: A historical record of 50 °De converts to 611.67 °R.
Engineering calculations
When working with legacy data or equipment that uses Delisle, convert to Rankine for thermodynamic calculations.
Example: Convert 200 °De to 431.67 °R for use in heat transfer equations.
Educational exercises
Practice temperature scale conversions to understand the relationships between different scales.
Example: Convert -100 °De to 791.67 °R.
提示与常见错误
Tips
- Remember that Delisle decreases as temperature increases, so higher Delisle values correspond to lower Rankine values.
- Absolute zero on the Delisle scale is approximately 559.725 °De, which converts to 0 °R.
- Use the formula °R = 671.67 - (°De × 6/5) for quick conversions.
- Double-check your arithmetic, especially when dealing with negative Delisle values.
Common Mistakes to Avoid
- Forgetting that the Delisle scale is inverted: higher Delisle means colder.
- Using the wrong factor: the correct multiplier is 6/5, not 5/6.
- Not accounting for the offset: the base is 671.67 °R, not 491.67 °R.
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.
