for an assignment I'm writing, I'm trying to find the % efficiency of ethanol.

We were given a chart that says ethanol's energy input (MJ/L) is 16.16 and its energy output is 23.58

% efficiency = energy output/energy input x100, so
23.57/16.16 x 100
I get 146%.
So does that mean "the percent efficiency of ethanol is 146%"?
