Calories Burned:  531 calories per hour   (based on a body weight of 150 lbs.)
The above calorie count is based on a weight of 188 pounds (85.35kg) and a flight of stairs being 4.47m high.  The formula is E = mgh / 1000 where E = energy in calories, m is the mass (your weight) in kg, g is gravity (9.81 m/s²), h is the height of the flight of stairs in meters.  In this case, E = (85.35) x (9.81) x (4.47) / 1000 = 3.74 calories per flight of stairs going up and about 1.40 calories burned going down (about 37½% of going up calories). 
It takes an average of 18 seconds to ascend one flight of stairs and about 10 seconds to descend one flight.  In order to compute the time for one hour of exercise, we need the formula 10f + 18f = 3600, which translates to 28f = 3600, and f = 128.57 flights of stairs in one hour round trip.  If I do, 128.57 flights of stairs up and 128.57 flights down, with going downstairs taking about 37.5% of the needed calories, this would produce this equation:

E = (3.74 cal/flt x 128.57 flts) + (1.40 cal/flt x 128.57 flts), so E = 661.65 calories per hour.

I suppose this is where it would be beneficial to use a fitbit ... Christmas just may come early for me this year :-)

Actually, no. The simple thing about this math is that no matter how long it takes someone to do this exercise, they will burn the same amount of calories. The same holds true for running versus walking. Running a mile and walking a mile burns the same number of calories. The difference is how much power is being expended to reduce the amount of time it talkes to acheive the goal.

I believe that what it is saying is that you would need to walk up and down a regular flight of stairs for an hour to burn 710.69 calories
