I'm just going to ignore fancy apps, gps, and physics all together: Figure out how many calories you consume on a typical/non-exercise day and multiply that by the days in your bike tour. Subtract that from the amount of calories you consumed during the tour, and that will be a pretty good estimate of how many calories the actual biking required.
If you're able to upload the ride to Garmin Connect, or Strava, you can get an estimate of calorie burn on the basis of speed, elevation, and so forth. If you were wearing a heart rate monitor, the estimate from Garmin will be much more accurate, but unfortunately at this time Strava does not factor heart rate into their calorie estimate.
To be honest, you're really asking this question too late. If you had asked before your tour, I believe the easiest way you could have measured it would be to find a cycling app which takes your weight and your other physical information. Then you simply weigh your fully loaded bike and add that weight to your own, then the app would measure your total ...
You can't. Calories burnt depends on your speed, elevation change, and your body composition. e.g. riding at 30mph burns more than double the calories per hour than 20mph. The calorie calculators just make a rough approximation, and their margin of error is significantly greater than the difference between their assumed bike weight and yours. Just take ...
If you look at former cyclocrossers who have moved into the pro peloton (Lars Boom, Zdenek Stybar come to mind), many of them end up specializing in the Spring Classics (Paris-Roubaix, etc). In the multi-day tours, they are all-rounders, capable of winning stages, though not usually near the top of the GC.
