1 calorie = 4.18 joules, although humans are about 25% efficient so you can approximate 1000 calories = 1 Calorie = 1 kilojoule.
Thanks for this explanation. So if in theory the op averaged 100w for a total of 264,000 joules (in one direction), how is calorie consumption calculated? I'm trying to make sense of your last sentence. If 1 calorie = 1 kilojoule, does that mean the op is burning roughly 528 calories total for the round trip?
