Question

how do u convert 7.68 cal/sec to kcal/min

Answer 1

First you have to convert 7.68 cal/sec to cal/min
to do that, just multiply by 60
So it will be 460.8 cal/min
now convert that to kcal/min

kcal = kilocalories = 1000 calories.

so just divide by 1000 and you'll have your answer in kcal/min :)
