Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (kelvin (K)) without arbitrary rounding:

Vtarget=Vsource×(ksource→SIktarget→SI)V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)

1. Source SI Bridge (ksource):1 °De = 1 kelvin (K)
2. Target SI Bridge (ktarget):1 K = 1 kelvin (K)
Step-by-step substitution for Delisle → Kelvin:V(K) = V(°De) × ( 1 / 1 ) = V(°De) × 372.483333

Understanding Delisle and Kelvin

Delisle

°De
Standard Unit

A Delisle (°De) is a recognized unit for thermodynamic temperature.

Applications & Practical Context

In practical temperature terms, a water boiling point temperature in historical Delisle scale equals 0 °De, a water freezing point temperature in inverted Delisle scale equals 150 °De.

Physical Setup

A reading of 1 °De represents a thermal intensity calibrated relative to the thermodynamic reference scale.

Conversion to SI Unit: kelvin (K)
1 °De = 1 K

Kelvin

K
SI Base Unit

The kelvin (K) is the primary base unit of thermodynamic temperature in the International System of Units (SI).

Applications & Practical Context

In practical temperature terms, a absolute zero: theoretical temperature where thermal motion ceases equals 0 K, a cosmic microwave background radiation temperature of deep space equals 2.725 K, a triple point of water international thermodynamic temperature standard equals 273.16 K.

Physical Setup

0 K represents absolute zero, the theoretical thermodynamic minimum at which all classical thermal motion ceases; 1 kelvin equals 1/273.16 of the thermodynamic temperature of water's triple point.
