I'm looking at comparing energy expenditures in two studies.
The first study published the energy expenditure of fat to be ~15 KJ/min.
The second study is listing data (and here is where I'm confused) as mg/kg*min
or KJ/kg*min.
What is the proper way to convert mg/kg*min to KJ/min. Is a KJ also equal to mass unit/mass unit? Help is appreciated.
