What does one kilojoule represent?

A kilojoule is an SI-derived energy unit equal to 1,000 joules, commonly used in science, engineering, and nutrition.

Why is the megaton unit used?

Megatons quantify extremely large energy amounts such as nuclear weapon yields, asteroid impacts, or massive explosions.

Is the megaton an SI unit?

No, the megaton is a non-SI unit based on the energy released by one million metric tons of TNT.

Browser-based tool accessible without installation

Examples

1,000 kJ converts to approximately 2.3900573613767e-10 megatons
10,000,000 kJ converts to approximately 2.3900573613767e-6 megatons

Common Use Cases

Analyzing energy from nuclear weapons and thermonuclear tests
Estimating energy released by large asteroid or comet impacts
Comparing energies of major explosions or volcanic events
Interpreting extremely large energy amounts in science and military studies

Tips & Best Practices

Use this tool for contextualizing very large energy values only
Remember that megaton is a non-SI unit mainly for approximate explosive energies
Interpret very small kilojoule inputs with caution due to minuscule megaton results
Consider the tool’s conversion rate as an approximation based on TNT equivalence

Limitations

Kilojoules and megatons differ by huge scales, making small inputs yield negligible megaton values
Megaton is not an SI unit and may not suit precise scientific calculations
Conversion assumes megaton equivalent to 4.184×10^15 joules based on TNT, which can vary
