How to convert gigatons of TNT to megatons of TNT
Mt = Gt × 1,000
To convert gigatons of TNT to megatons of TNT, multiply the number of gigatons of TNT by 1,000.
Example: 1 Gt to Mt
Start with the value in gigatons of TNT: 1 Gt.
Multiply by 1,000: 1 × 1,000 = 1,000.
Result: 1 gigaton of TNT = 1,000 megatons of TNT .
Going the other way, 1 megaton of TNT = 0.001 gigatons of TNT, so to convert megatons of TNT back to gigatons of TNT you divide by the same number. See megatons of TNT to gigatons of TNT .
