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.

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.
