How to convert grams of TNT to kilojoules

kJ = g TNT × 4.184

To convert grams of TNT to kilojoules, multiply the number of grams of TNT by 4.184.

Example: 1 g TNT to kJ

  1. Start with the value in grams of TNT: 1 g TNT.
  2. Multiply by 4.184: 1 × 4.184 = 4.184.
  3. Result: 1 gram of TNT = 4.184 kilojoules.

Going the other way, 1 kilojoule = 0.239005736138 grams of TNT, so to convert kilojoules back to grams of TNT you divide by the same number. See kilojoules to grams of TNT.
