The density of water in the si system is a. 1kg/m3
b. 1000 kg/m3

0.000001 kg/cm3. 1 kg/dm3 = 1 kg/L = 1000 g/1000 cm3 = 1 g/cm3 = 1 g/ml (water). Water as the reference with its highest density at 3.98 °C is ρ = 1 g/cm3.

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
