11.3 Apply any hydrometer correction to the observed
reading and record the corrected hydrometer scale reading to
the nearest 0.1 kg/m3 in density, 0.0001 g/mL, kg/L or relative
density, or 0.1° API.
11.4 If the hydrometer has been calibrated at a temperature
other than the reference temperature, use the equation below to
correct the hydrometer scale reading:
