When working with temperature measurements, precision is essential. Whether you are a scientist, student, or engineer, converting between temperature scales accurately is critical. In this article, we will walk you through the step-by-step process to convert 345.871 Delisle (°De) into Nanokelvin (nK) using the accurate formula and explain the conversion process thoroughly.
Delisle (°De)
The Delisle scale, abbreviated as °De, is a lesser-known temperature scale created by the French astronomer Joseph-Nicolas Delisle in the 18th century. The unique feature of this scale is that it decreases as temperature increases. On this scale:
- 0 °De corresponds to the boiling point of water (100 °C).
- 150 °De corresponds to the freezing point of water (0 °C).
This inverse nature of the Delisle scale is an important factor in the conversion process.
Nanokelvin (nK)
A nanokelvin (nK) is one-billionth of a kelvin (K), making it an extremely precise unit used in scientific measurements, especially in physics experiments near absolute zero.
1 nK = 10⁻⁹ K
Converting to nanokelvin allows scientists to work on ultra-cold temperature experiments and quantum research.
Conversion Formula: Delisle to Kelvin
To convert Delisle (°De) to Kelvin (K), use the following formula: K=373.15−(°De×23)K = 373.15 – \left(\frac{°De \times 2}{3}\right)K=373.15−(3°De×2)
Where:
- 373.15 K is the boiling point of water in Kelvin.
- °De is the temperature in Delisle.
This formula helps convert any Delisle value into Kelvin, which can then be converted to nanokelvin.
Step-by-Step Conversion Process
Let’s convert 345.871 °De into nanokelvin.
Step 1: Convert Delisle to Kelvin
K=373.15−345.871×23K = 373.15 – \frac{345.871 \times 2}{3}K=373.15−3345.871×2
Calculate the multiplication first: 345.871×2=691.742345.871 \times 2 = 691.742345.871×2=691.742
Next, divide by 3: 691.742÷3=230.5806667691.742 ÷ 3 = 230.5806667691.742÷3=230.5806667
Finally, subtract from 373.15: 373.15−230.5806667≈142.5693 K373.15 – 230.5806667 ≈ 142.5693 \, K373.15−230.5806667≈142.5693K
So, 345.871 °De ≈ 142.5693 K
Step 2: Convert Kelvin to Nanokelvin
Since 1 K = 1 × 10⁹ nK, we multiply the Kelvin value by 10⁹: 142.5693 K×109=1.425693×1011 nK142.5693 \, K × 10^9 = 1.425693 × 10^{11} \, nK142.5693K×109=1.425693×1011nK
So, 345.871 Delisle ≈ 1.425693 × 10¹¹ Nanokelvin.
Quick Reference Formula
For convenience, here’s the direct formula from Delisle to Nanokelvin: nK=(373.15−°De×23)×109nK = \left(373.15 – \frac{°De \times 2}{3}\right) × 10^9nK=(373.15−3°De×2)×109
Using this formula, you can quickly convert any Delisle temperature to nanokelvin with precision.
Practical Applications
