Jobisdone [24]

6.6 × 10^{10} J = 6.2 × 10^{7} British thermal units

First of all, we should know that 1 British thermal unit = 1055 Joules.

From question, heat = 6.6 × 10^{10} J

1 BTU = 1055 J

6.6 × 10^{10} J = \frac{1}{1055} ×  6.6 × 10^{10} British thermal units

                   = 6.2 × 10^{7} British thermal units

1000 Joules = 1 kilojoule
