Bike Calculator - Reliable?

[Aushiker]

Hi

Looking around for reasonably good calculator of calories burnt. Just want something that will produce numbers that are reasonably accurate for using CalorieKing.com.au.

I have played with Bike Calculator but the calorie numbers just seem to high. Has anyone got any thoughts on is accuracy levels?

Maybe other suggestions for formula or an online calculator?

Thanks
Andrew

Good luck if not using a power meter.

I would be interested to see if someone had compared their calories burnt on a power meter with what a Polar HRM says, and perhaps what some of these calculators say.
