How to convert British thermal units to tons of TNT

t TNT = BTU × 2.521644 × 10-7

To convert British thermal units to tons of TNT, multiply the number of British thermal units by 2.521644 × 10-7.

Example: 10 BTU to t TNT

  1. Start with the value in British thermal units: 10 BTU.
  2. Multiply by 2.521644 × 10-7: 10 × 2.521644 × 10-7 = 0.000002521644.
  3. Result: 10 British thermal units = 0.000002521644 tons of TNT.

Going the other way, 1 ton of TNT = 3,965,666.83139 British thermal units, so to convert tons of TNT back to British thermal units you divide by the same number. See tons of TNT to British thermal units.
