Non uniform pressure - Newbie question

[L17Aurora]

In the example of the fuel tank (in imperial units) for the non uniform pressure example in the cosmos online tutorial the constant of 0.029 for the weight of the liquid. Am I right in thinking for metric units (SI) I insert 0.0008 here (for the same liquid)
Thanks

dp/dh=[ρ]g

pressure change per unit height change = fluid density * gravity

I should have studied the units more
