I think you want to convert kg/m3 right?

Well 1 kg is how many slugs?

How many m3 are in a gal?

1 kg=0.068521 slug
1 gal =0.003785 m^3

(6.21*10^3) kg /m^3= (6.21*10^3) *(0.068521)*0.003785 slug/gal

1 kg=0.068521 slug

(6.21*10^3) kg /m^3= (6.21*10^3) *(0.068521)*0.003785 slug/gal

right so 1 kg=0.068521 slug and 1m3 = 264.172052358. You are converting 1 kg/ 1 m3. So you are correct in what you are doing, but you need to divide, not multiply.
