Kilojoules to Tons of TNT Converter

1 kilojoule (kJ) equals 2.3900574 × 10-7 tons of TNT (t TNT).

Quick answer

  • 1 kilojoule = 2.3900574 × 10-7 tons of TNT
  • 1 ton of TNT = 4,184,000 kilojoules
  • Formula: t TNT = kJ ÷ 4,184,000

1 kilojoule = 2.3900574 × 10-7 tons of TNT

How to convert kilojoules to tons of TNT

t TNT = kJ ÷ 4,184,000

To convert kilojoules to tons of TNT, divide the number of kilojoules by 4,184,000.

Example: 10 kJ to t TNT

  1. Start with the value in kilojoules: 10 kJ.
  2. Divide by 4,184,000: 10 ÷ 4,184,000 = 0.000002390057.
  3. Result: 10 kilojoules = 0.000002390057 tons of TNT.

Going the other way, 1 ton of TNT = 4,184,000 kilojoules, so to convert tons of TNT back to kilojoules you multiply by the same number. See tons of TNT to kilojoules.
