Gigatons of TNT to Thermochemical BTUs Converter

1 gigaton of TNT (Gt) equals 3.9683207 × 1015 thermochemical BTUs (BTU_th).

Quick answer

  • 1 gigaton of TNT = 3.9683207 × 1015 thermochemical BTUs
  • 1 thermochemical BTU = 2.5199576 × 10-16 gigatons of TNT
  • Formula: BTU_th = Gt × 3.9683207 × 1015

1 gigaton of TNT = 3.9683207 × 1015 thermochemical BTUs

How to convert gigatons of TNT to thermochemical BTUs

BTU_th = Gt × 3.9683207 × 1015

To convert gigatons of TNT to thermochemical BTUs, multiply the number of gigatons of TNT by 3.9683207 × 1015.

Example: 1 Gt to BTU_th

  1. Start with the value in gigatons of TNT: 1 Gt.
  2. Multiply by 3.9683207 × 1015: 1 × 3.9683207 × 1015 = 3.9683207 × 1015.
  3. Result: 1 gigaton of TNT = 3.9683207 × 1015 thermochemical BTUs.

Going the other way, 1 thermochemical BTU = 2.5199576 × 10-16 gigatons of TNT, so to convert thermochemical BTUs back to gigatons of TNT you divide by the same number. See thermochemical BTUs to gigatons of TNT.
