Tons of TNT to moment magnitude
Type a value in t TNT to get it in Mw instantly.
3.733Mw
That's 13× as much energy as a quake you can feel, while a minor quake is 79× more. That energy could run a home for about 0.6457 years.
Convert the other way: Mw to t TNT
What it means
How much energy is that?
Uses the standard relation log₁₀E = 1.5M + 4.8. Reported magnitudes vary slightly between agencies and methods.
The math
How to convert t TNT to Mw
Magnitude is logarithmic energy: log₁₀E = 1.5M + 4.8, so one whole magnitude is about 32 times the energy.
Example: 6 t TNT = 3.73316 Mw.
