Dus is die SG van water by 60 °F in Amerikaanse/Britse eenhede:
:<math>SG_{water,60^\circ F,Amerikaans} = \frac{\rho_{w,60^\circ F}}{\rho_{w,60^\circ F}} = \frac{998.8666 \ kg/m^3}{998.8666 \ kg/m^3} = 1</math>
Die SG van water by 60 °F (15.556 °C) in standaardeenhede is egter in terme van water by 4 °C en is dus:
:<math>SG_{water,60^\circ F,Standaard} = \frac{\rho_{w,15.\dot{5}^\circ C}}{\rho_{w,4^\circ C}} = \frac{998.8666 \ kg/m^3}{1000 \ kg/m^3} = 0.9988666</math>
