city biking

Options
Hi everyone! I'm a bike commuter so I bike 3 miles each way to school, one way is mostly downhill and the other way is mostly uphill. It takes 20-25 minutes each way. I'm having trouble figuring out how many calories this actually burns since everything I've found seems to relate it to minutes done in a controlled environment (city biking allows you to take advantage of hills and you also stop at lights occasionally), so I don't think I can count the total time I biked nor can I count the total miles I biked NOR can I count the average mph (usually around 14-17 on the downhill route, <10 uphill) because of the previously stated reasons.

Has anyone else figured something out?
I've just been estimating but I'd rather have a more scientific approach...

    They only way to really know is to wear a heart rate monitor that calculates calories. I would just take the average of the different values the calorie predictors are saying.
