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 Mton TNT = 4.184001 × 10¹⁵ joule (J)
2. Target SI Bridge (ktarget):1 nJ = 1 × 10⁻⁹ joule (J)
Step-by-step substitution for Megaton → Nanojoule:V(nJ) = V(Mton TNT) × ( 4.184001 × 10¹⁵ / 1 × 10⁻⁹ ) = V(Mton TNT) × 4.184001 × 10²⁴
Mathematical FormulaValue in Nanojoule = Value in Megaton × 4.18400063 × 10²⁴Direct computational formula applied for standard conversion.
Worked Example

To convert 120 Megaton (Mton TNT) to Nanojoule (nJ): multiply 120 by 4.184001 × 10²⁴ to get 5.020801 × 10²⁶ nJ. At an industrial engineering scale, 10000 Mton TNT converts to 4.184001 × 10²⁸ nJ.

Inverse check: 1 nJ = 2.390057 × 10⁻²⁵ Mton TNT.
