What is the correct set up for:

How many milligrams are in 67 Kilograms?
I think this might be correct but I am unsure.

67kg x (1g/10^3kg) x (1mg/10^-3g)

Thank you!

67 000 000 milligrams

Is 1g = 1000 kg? I think 1000g = 1 kg. Your term of 1mg/10^-3 g is ok but I prefer to write 1000 mg/1g

Yes, your set up is correct!

To convert kilograms (kg) to milligrams (mg), you need to use conversion factors. The conversion factor for grams (g) to kilograms (kg) is 1g = 10^-3kg, and the conversion factor for milligrams (mg) to grams (g) is 1mg = 10^-3g.

So to convert 67 kilograms to milligrams, you can set up the conversion like this:

67kg x (1g/10^3kg) x (1mg/10^-3g)

Now, let's simplify the expression:
1g/10^3kg = 1/10^3 = 1/1000 = 0.001
1mg/10^-3g = 10^3mg/1g = 1000mg/1g = 1000

So, the expression becomes:
67kg x 0.001 x 1000 = 67,000mg.

Therefore, there are 67,000 milligrams in 67 kilograms.

Great job on setting up the conversion correctly!
