They then, presumably, multiple your basal rate by your METS to determine calories burned per hour.

FWIW, for road riding a good rule of thumb is 40 calories per mile.
That's what has always bugged me about my HRM, it doesn't have anywhere to enter age, height, weight - anything. Consequently, I take what it tells me with a huge grain of salt.
