WebAug 13, 2011 · So, using a heating value of 115,000 Btu/gal, 7,500 gallons of gasoshine releases about 863 million Btu. Now the question is; how many megawatts is that. By definition, a Btu is about 1054.8 Joules, and a Watt is 1 Joule per second. So if we release 8.63 E8 Btu’s, we would release about 910 gigaoules. WebVedantu.
