Hi Paul,
Unfortunately, calorie terminology is confusing. A food calorie (kilogram calorie), is a kcal, i.e. a thousand calories (gram calories). This should account for "goofing on a few decimal points". The conversion to kWh is fine - W/annum is the rate of consumption, which you convert to kWh by multiplying by the number of hours in a year (8,766) and dividing by 1,000.
Hope that helps.
