Density & specific gravity measurements Hydrometers
Density hydrometerConcept : mass per unit of volume (ρ) SI Graduations in g/ml - kg/m3 USC Graduations in ppg Reference temperatures SI 20°C USC : 70°C ( 21.1°C)
Relative density (specific gravity) hydrometerConcept : ratio of ρ sample by ρ water at the same temperatureGraduation dimensionless Reference temperature 15.56°C /60°FRatio of sample density to water density at 60°F :
999,012 kg/m3 ≡ 0, 999 012 g/ml (8,337 ppg)

Reference & Reporting temperatureISO 387 Reference temperature
• Clause 4.1 - density hydrometer : − 20 °C (68°F) − In special circumstances : substitution to 15°C (59°F) or 27°C
(80.6°F)− 27°C i.e 80°F recommended − other reference temperatures ? USA : 70 °F ?
• Clause 4.2 : relative density hydrometer − 60°F ( 15,56°C) for liquid and water
Density reporting temperature For any measurement done at a temperature which is not the reference one, a
correction is required. General reporting : when density hydrometer is used why to report at a
different temperature than the reference ’s one ? Does it need to get a direct conversion between SI ref. temperature to
USC’s (20°C – 68°F) or between USC ref. temperature to SI’s (70°F – 21°C) ?
• Reporting temperature proposal : SI report : 20°C USC report : 70°F Left to users

Temperature Correction factor
Density hydrometer • Only a correction linked to hydrometer volumetric
change is required : − Standard glass thermal volume expansion 20 x 10-6 − Table linked to readings and temperature − Minor difference lower than uncertainty if the same
table is used for 20°C or 70°F as reference temperature
− Two tables ( SI and USC) possible

TG # 6
Temperature Correction factor
Relative density hydrometer• Reference temperature 60°F • Correction whatever the reporting temperature • Correction linked to
− Glass volumetric change − Water temperature density variation
Correction factor : − Complex equation − tables of coefficient − variations as per author/references
