If my understanding is correct there is curious difference in perceived scale with kinetic vs thermal energy. Based on a a rowing machine's advertised metrics, I calculated you could row across the English channel on half a packet of chocolate biscuits.
I'm not sure if this impacts your scenario, but the "calorie" commonly used in nutrition is actually a "kcal", or a thousand calories as used by physicists. Most confusing term for units ever.
Put another way: I’ll have to spend an hour on the treadmill to work off the calories in this burger.
This sounds interesting but I don't really understand, could you elaborate?
1 biscuit = 85 cal
1000m rowing = 60 cal [1]
English Channel = 35km (narrowest point)
35 * 60 / 85 = 24.7 biscuits!

Ah, got it. That's cool, thanks for sharing!
