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
