Jun 23, 2013 · All hydrometers are calibrated to be accurate at a given temperature. Most newer hydrometers are calibrated for 68 degrees (F). Because the density of fluids changes as their temperature changes if you don’t measure your specific gravity at your hydrometers calibration temperature you’re going to get an inaccurate reading. concentrations of these various compounds. The API gravity of a particular crude is merely a measure of its specific gravity, or density. The higher the API number, expressed as degrees API or degrees API, the less dense (lighter, thinner) is the crude. Conversely, the lower the degrees API, the more dense (heavier, thicker) is the crude.
