Fitness, exercise, and weight loss lead to constant self-tutoring. The tutor shares an interesting find about rest metabolic rate (RMR).
Reading physics.stackexchange.com (Martin and Martin Beckett), I read the observation that you burn 80 to 100 Watts (depending on height, weight, and so on) just existing. Curious to verify the claim, I looked for an independent opinion.
Do the two claims agree? In fact, they exactly do, and here’s how:
Typically, 1900 fitness calories means 1900×1000=1900000 physics calories. One physics calorie=4.184J, so
1900 calories per day = 1900000×4.184 = 7949600J per day.
1 Watt = 1J/s, so we divide Joules (J) per day by seconds in one day:
7949600÷(24x60x60) = 92J/s = 92 Watts
So the two claims – that you burn 80 to 100 Watts at rest, and that you burn 1900 calories per day at rest – equate.
I’ll be talking more about the general issue of energy usage:)
