Gigajoule to megaton of TNT converter (gj to mttnt)

Conversion Formula

1 gj = 2.39e-7 mttnt

Step-by-Step Explanation

1. Understand the base relationship:
   1 Gigajoule = 1.00G joules
   1 Megaton of TNT = 4.18P joules
2. Establish the conversion factor:
   1 gj = (1.00G J) / (4.18P J/mttnt) = 2.39e-7 mttnt
3. Apply the conversion:
   Multiply the value in gj by 2.39e-7 to get the equivalent in mttnt

Example Conversion

Convert 5 gj to mttnt:

5 gj × 2.39e-7 = 1.20e-6 mttnt
