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 (joule (J)) 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)
Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)
1. Source SI Bridge (ksource):1 Gton TNT = 4.184001 × 10¹⁸ joule (J)
2. Target SI Bridge (ktarget):1 nJ = 1 × 10⁻⁹ joule (J)
Step-by-step substitution for Gigaton → Nanojoule:V(nJ) = V(Gton TNT) × ( 4.184001 × 10¹⁸ / 1 × 10⁻⁹ ) = V(Gton TNT) × 4.184001 × 10²⁷
Mathematical FormulaValue in Nanojoule = Value in Gigaton × 4.18400063 × 10²⁷Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 36 Gton TNT, applying the conversion factor yields exactly 1.50624 × 10²⁹ nJ. At larger operational scale, 240 Gigaton corresponds to 1.00416 × 10³⁰ nJ.

Inverse check: 1 nJ = 2.390057 × 10⁻²⁸ Gton TNT.
