How to Convert Gigawatt-hour to Megaton of TNT

1 gwh = 8.60e-4 mttnt

Understand the base relationship:
1 Gigawatt-hour = 3.60T joules
1 Megaton of TNT = 4.18P joules
Establish the conversion factor:
1 gwh = (3.60T J) / (4.18P J/mttnt) = 8.60e-4 mttnt
Apply the conversion:
Multiply the value in gwh by 8.60e-4 to get the equivalent in mttnt

Convert 5 gwh to mttnt:

5 gwh × 8.60e-4 = 0.004302 mttnt
