Again from Rowlett:

quad

a unit of energy equal to 10^15 (one quadrillion) Btu or about 1.055 petajoules or 293.07 terawatt hours (TWh).

>From Cardarelli:

        1 quad = 1.05505585262 x 10^15 J

I think a factor of 1000 got lost in Louis' numbers.  I get

        1 quad = 1055 petajoules,

and my edition of Cardarelli says

        1 quad = 1.05505585262 X 10^18 J

Correct. Thanks for having detected the error.
