Kilograms of TNT to Millijoules Converter

1 kilogram of TNT (kg TNT) equals 4,184,000,000 millijoules (mJ).

Quick answer

  • 1 kilogram of TNT = 4,184,000,000 millijoules
  • 1 millijoule = 2.3900574 × 10-10 kilograms of TNT
  • Formula: mJ = kg TNT × 4,184,000,000

1 kilogram of TNT = 4,184,000,000 millijoules

How to convert kilograms of TNT to millijoules

mJ = kg TNT × 4,184,000,000

To convert kilograms of TNT to millijoules, multiply the number of kilograms of TNT by 4,184,000,000.

Example: 1 kg TNT to mJ

  1. Start with the value in kilograms of TNT: 1 kg TNT.
  2. Multiply by 4,184,000,000: 1 × 4,184,000,000 = 4,184,000,000.
  3. Result: 1 kilogram of TNT = 4,184,000,000 millijoules.

Going the other way, 1 millijoule = 2.3900574 × 10-10 kilograms of TNT, so to convert millijoules back to kilograms of TNT you divide by the same number. See millijoules to kilograms of TNT.
