What is the correct set up for:
How many milligrams are in 67 Kilograms?
Is this correct:
67kg x (1g/10^3kg) x (1mg/10^3g)
Thank you!

Online "*" is used to indicate multiplication, so "x" is not confused with standing for an unknown.
There are 1000 grams in a kilogram and 1000 milligrams in a gram.
67 * 1000 * 1000 = 67*10^6
