The total energy supply in the United states in 2011 was 107 x 1015 Btu. Express this value in joules and calories.

Answer 1

Hello, Honey,

I'll assume 107x1015 is 1.07x10¹⁵ Btu

Conversion factors:

1055.87 J/Btu

252 cal/Btu

Joules: (1.07x10¹⁵ Btu)*(1055.87 J/Btu) = 1.13x10²⁰ J

cal: (1.07x10¹⁵ Btu)*(252 cal/Btu) = 2.70x10¹⁹ Btu
